-## @mainpage RPKI Engine Reference Manual
-#
-# This collection of Python modules implements a prototype of the
-# RPKI Engine. This is a work in progress.
-#
-# See http://viewvc.hactrn.net/subvert-rpki.hactrn.net/ for code,
-# design documents, a text mirror of portions of APNIC's Wiki, etc.
-#
-# The RPKI Engine is an implementation of the production-side tools
-# for generating certificates, CRLs, and ROAs. The
-# <a href="http://viewvc.hactrn.net/subvert-rpki.hactrn.net/rcynic/">relying party tools</a>
-# are a separate (and much simpler) package.
-#
-# The Subversion repository for the entire project is available for
-# (read-only) anonymous access at http://subvert-rpki.hactrn.net/.
-#
-# The documentation you're reading is generated automatically by
-# Doxygen from comments and documentation in
-# <a href="http://viewvc.hactrn.net/subvert-rpki.hactrn.net/rpkid/rpki/">the code</a>.
-#
-# Besides the automatically-generated code documentation, this manual
-# also includes documentation of the overall package:
-#
-# @li The @subpage Installation "installation instructions"
-# @li The @subpage Operation "operation instructions"
-# @li A description of the @subpage Left-right "left-right protocol"
-# @li A description of the @subpage Publication "publication protocol"

-## @page Installation Installation Guide
-#
-# Preliminary installation instructions for rpkid et al. These are the
-# production-side RPKI tools, for Internet Registries (RIRs, LIRs, etc).
-# See the "rcynic" program for relying party tools.
-#
-# rpkid is a set of Python modules supporting generation and maintenance
-# of resource certificates. Most of the code is in the rpkid/rpki/
-# directory. rpkid itself is a relatively small program that calls the
-# library modules. There are several other programs that make use of
-# the same libraries, as well as a collection of test programs.
-#
-# At present the package is intended to be run out of its build
-# directory. Setting up proper installation in a system area using the
-# Python distutils package would likely not be very hard but has not yet
-# been done.
-#
-# Note that initial development of this code has been on FreeBSD, so
-# installation will probably be easiest on FreeBSD.
-#
-# Before attempting to build the package, you need to install any
-# missing prerequisites. Note that the Python code requires Python
-# version 2.5. rpkid et al are mostly self-contained, but do require
-# a small number of external packages to run.
-#
-# <ul>
-# <li>
-# If your Python installation does not already include the sources
-# files needed to compile new Python extension modules, you will
-# need to install whatever package does include those source
-# files. The need for and name of this package varies from system
-# to system. On FreeBSD, the base Python interpreter package
-# includes the development sources; on at least some Linux
-# distributions, you have to install a separate "python-devel"
-# package or something similar. If you get compilation errors
-# trying to build the POW code (below) and the error message says
-# something about the file "Python.h" being missing, this is
-# almost certainly your problem.
-# </li>
-#
-# <li>
-# <a href="http://codespeak.net/lxml/">http://codespeak.net/lxml/</a>.
-# lxml in turn requires the Gnome LibXML2 C libraries.
-# <ul>
-# <li>FreeBSD: /usr/ports/devel/py-lxml</li>
-# <li>Fedora: python-lxml.i386</li>
-# <li>Ubuntu: python-lxml</li>
-# </ul>
-# </li>
-#
-# <li>
-# <a href="http://sourceforge.net/projects/mysql-python/">http://sourceforge.net/projects/mysql-python/</a>.
-# MySQLdb in turn requires MySQL client and server. rpkid et al have
-# been tested with MySQL 5.0 and 5.1.
-# <ul>
-# <li>FreeBSD: /usr/ports/databases/py-MySQLdb</li>
-# <li>Fedora: MySQL-python.i386</li>
-# <li>Ubuntu: python-mysqldb</li>
-# </ul>
-# </li>
-# </ul>
-#
-# rpkid et al also make heavy use of a modified copy of the Python
-# OpenSSL Wrappers (POW) package, but this copy has enough modifications
-# and additions that it's included in the subversion tree.
-#
-# The next step is to build the OpenSSL and POW binaries. At present
-# the OpenSSL code is just a snapshot of the OpenSSL development
-# sources, compiled with special options to enable RFC 3779 support
-# that ISC wrote under previous contract to ARIN. The POW (Python
-# OpenSSL Wrapper) library is an extended copy of the stock POW
-# release.
-#
-# To build these, cd to the top-level directory in the distribution and
-# type "make".
-#
-# @verbatim
-# $ cd $top
-# $ make
-# @endverbatim
-#
-# This should automatically build everything, in the right order,
-# including staticly linking the POW extension module with the OpenSSL
-# library to provide RFC 3779 support. If you get errors building
-# POW, see the above discussion of Python development sources.
-#
-# You will also need a MySQL installation. This code was developed
-# using MySQL 5.1 and has been tested with MySQL 5.0 and 5.1.
-#
-# The architecture is intended to support hardware signing modules
-# (HSMs), but the code to support them has not been written.
-#
-# At this point, you should have all the necessary software installed.
-# You will probably want to test it. All tests should be run from the
-# rpkid/ directory. The test suite requires a few more external
-# packages, only one of which is Python code.
-#
-# <ul>
-# <li>
-# <a href="http://pyyaml.org/">http://pyyaml.org/</a>.
-# testpoke.py (an up-down protocol command line test client) and
-# testbed.py (a test harness) use PyYAML.
-# <ul>
-# <li>FreeBSD: /usr/ports/devel/py-yaml</li>
-# <li>Ubuntu: python-yaml</li>
-# </ul>
-# </li>
-#
-# <li>
-# <a href="http://xmlsoft.org/XSLT/">http://xmlsoft.org/XSLT/</a>.
-# Some of the test code uses xsltproc, from the Gnome LibXSLT
-# package.
-# <ul>
-# <li>FreeBSD: /usr/ports/textproc/libxslt</li>
-# <li>Ubuntu: xsltproc</li>
-# </ul>
-# </li>
-#
-# <li>
-# <a href="http://w3m.sourceforge.net/">http://w3m.sourceforge.net/</a>.
-# testbed.py uses w3m to display the summary output from rcynic.
-# Nothing terrible will happen if w3m isn't available, testbed.py
-# will just complain about it being missing and won't display
-# rcynic's output.
-# <ul>
-# <li>FreeBSD: /usr/ports/www/w3m</li>
-# <li>Ubuntu: w3m</li>
-# </ul>
-# </li>
-# </ul>
-#
-# Some of the tests require MySQL databases to store their data. To set
-# up all the databases that the tests will need, run the SQL commands in
-# rpkid/testbed.setup.sql. The MySQL command line client is usually the
-# easiest way to do this, eg:
-#
-# @verbatim
-# $ cd $top/rpkid
-# $ mysql -u root -p <testbed.setup.sql
-# @endverbatim
-#
-# To run the tests, run "make all-tests":
-#
-# @verbatim
-# $ cd $top/rpkid
-# $ make all-tests
-# @endverbatim
-#
-# If nothing explodes, your installation is probably ok. Any Python
-# backtraces in the output indicate a problem.
-#
-# There's a last set of tools that only developers should need, as
-# they're only used when modifying schemas or regenerating the
-# documentation. These tools are listed here for completeness.
-#
-# <ul>
-# <li>
-# <a href="http://www.doxygen.org/">http://www.doxygen.org/</a>.
-# Doxygen in turn pulls in several other tools, notably Graphviz,
-# pdfLaTeX, and Ghostscript.
-# <ul>
-# <li>FreeBSD: /usr/ports/devel/doxygen</li>
-# <li>Ubuntu: doxygen</li>
-# </ul>
-# </li>
-#
-# <li>
-# <a href="http://lynx.isc.org/current/">http://lynx.isc.org/current/</a>.
-# The documentation build process uses xsltproc and Lynx to dump
-# flat text versions of a few critical documentation pages.
-# <ul>
-# <li>FreeBSD: /usr/ports/www/lynx</li>
-# <li>Ubuntu: lynx</li>
-# </ul>
-# </li>
-#
-# <li>
-# <a href="http://www.thaiopensource.com/relaxng/trang.html">http://www.thaiopensource.com/relaxng/trang.html</a>.
-# Trang is used to convert RelaxNG schemas from the human-readable
-# "compact" form to the XML form that LibXML2 understands. Trang in
-# turn requires Java.
-# <ul>
-# <li>FreeBSD: /usr/ports/textproc/trang</li>
-# </ul>
-# </li>
-#
-# <li>
-# <a href="http://search.cpan.org/dist/SQL-Translator/">http://search.cpan.org/dist/SQL-Translator/</a>.
-# SQL-Translator, also known as "SQL Fairy", includes code to parse
-# an SQL schema and dump a description of it as Graphviz input.
-# SQL Fairy in turn requires Perl.
-# <ul>
-# <li>FreeBSD: /usr/ports/databases/p5-SQL-Translator</li>

-## @page Operation Operation Guide
-#
-# Preliminary operation instructions for rpkid et al. These are the
-# production-side RPKI tools, for Internet Registries (RIRs, LIRs, etc).
-# See rcynic/README for relying party tools.
-#
-# @warning
-# rpkid is still in development, and the code changes more often than
-# the hand-maintained portions of this documentation. The following
-# text was reasonably accurate at the time it was written but may be
-# obsolete by the time you read it.
-#
-# At present the package is intended to be run out of the @c rpkid/
-# directory.
-#
-# In addition to the library routines in the @c rpkid/rpki/ directory,
-# the package includes the following programs:
-#
-# @li @c rpkid.py:
-# The main RPKI engine daemon.
-#
-# @li @c pubd.py:
-# The publication engine daemon.
-#
-# @li @c rootd.py:
-# A separate daemon for handling the root of an RPKI
-# certificate tree. This is essentially a stripped down
-# version of rpkid with no SQL database, no left-right
-# protocol implementation, and only the parent side of
-# the up-down protocol. It's separate because the root
-# is a special case in several ways and it was simpler
-# to keep the special cases out of the main daemon.
-#
-# @li @c irdbd.py:
-# A sample implementation of an IR database daemon.
-# rpkid calls into this to perform lookups via the
-# left-right protocol.
-#
-# @li @c irbe_cli.py:
-# A command-line client for the left-right control
-# protocol.
-#
-# @li @c cross_certify.py:
-# A BPKI cross-certification tool.
-#
-# @li @c cronjob.py:
-# A trivial HTTP client used to drive rpkid cron events.
-#
-# @li @c testbed.py:
-# A test tool for running a collection of rpkid and irdb
-# instances under common control, driven by a unified
-# test script.
-#
-# @li @c testpoke.py:
-# A simple client for the up-down protocol, mostly
-# compatable with APNIC's rpki_poke.pl tool.
-#
-# Most of these programs take configuration files in a common format
-# similar to that used by the OpenSSL command line tool. The test
-# programs also take input in YAML format to drive the tests. Runs of
-# the testbed.py test tool will generate a fairly complete set
-# configuration files which may be useful as examples.
-#
-# Basic operation consists of creating the appropriate MySQL databases,
-# starting rpkid, pubd, rootd, and irdbd, using the left-right control
-# protocol to set up rpkid's internal state, and setting up a cron job
-# to invoke rpkid's cron action at regular intervals. All other
-# operations should occur either as a result of cron events or as a
-# result of incoming left-right and up-down protocol requests.
-#
-# Note that the full event-driven model for rpkid hasn't yet been
-# implemented. The design is intended to allow an arbitrary number of
-# hosted RPKI engines to run in a single rpkid instance, but without the
-# event-driven tasking model one must set up a separate rpkid instance
-# for each hosted RPKI engine.
-#
-# At present the daemon programs all run in foreground, that is, if one
-# wants them to run in background one must do so manually, eg, using
-# Bourne shell syntax:
-#
-# @verbatim
-# $ python whatever.py &
-# $ echo >whatever.pid "$!"
-# @endverbatim
-#
-# All of the daemons use syslog by default. To make them log to
-# stderr instead, use the "-d" option.
-#
-# @section CommonOptions Common Options
-#
-# Some of the options that the several daemons take are common to all
-# daemons. Which daemon they affect depends only on which sections of
-# which config files they are in.
-#
-# The first group of options are debugging flags, which can be set to
-# "true" or "false". If not specified, default values will be chosen
-# (generally false).
-#
-# @li @c debug_http
-# Enable verbose http debug logging.
-# @li @c debug_tls_certs
-# Enable verbose logging about tls certs.
-#
-# @li @c want_persistent_client
-# Enable http 1.1 persistence, client side.
-#
-# @li @c want_persistent_server
-# Enable http 1.1 persistence, server side.
-#
-# @li @c debug_cms_certs
-# Enable verbose logging about cms certs.
-#
-# @li @c sql_debug
-# Enable verbose logging about sql operations.
-#
-# @li @c gc_debug
-# Enable scary garbage collector debugging.
-#
-# @li @c timer_debug
-# Enable verbose logging of timer system.
-#
-# There are also a few options that allow you to save CMS messages for
-# audit or debugging. The save format is a simple MIME encoding in a
-# Maildir-format mailbox. The current options are very crude, at some
-# point we may provide finer grain controls.
-#
-# @li @c dump_outbound_cms
-# Dump messages we send to this mailbox.
-#
-# @li @c dump_inbound_cms
-# Dump messages we receive to this mailbox.
-#
-#
-# @section rpkid rpkid.py
-#
-# rpkid is the main RPKI engine daemon. Configuration of rpkid is a
-# two step process: a %config file to bootstrap rpkid to the point
-# where it can speak using the @link Left-right left-right protocol,
-# @endlink followed by dynamic configuration via the left-right
-# protocol. In production use the latter stage would be handled by
-# the IRBE stub; for test and develoment purposes it's handled by the
-# irbe_cli.py command line interface or by the testbed.py test
-# framework.
-#
-# rpkid stores dynamic data in an SQL database, which must have been
-# created for it, as explained in the @link Installation installation
-# guide. @endlink
-#
-# The default %config file is rpkid.conf, start rpkid with "-c filename"
-# to choose a different %config file. All options are in the section
-# "[rpkid]". Certificates, keys, and trust anchors may be in either DER
-# or PEM format.
-#
-# %Config file options:
-#
-# @li @c startup-message:
-# String to %log on startup, useful when
-# debugging a collection of rpkid instances at
-# once.
-#
-# @li @c sql-username:
-# Username to hand to MySQL when connecting to
-# rpkid's database.
-#
-# @li @c sql-database:
-# MySQL's database name for rpkid's database.
-#
-# @li @c sql-password:
-# Password to hand to MySQL when connecting to
-# rpkid's database.
-#
-# @li @c bpki-ta:
-# Name of file containing BPKI trust anchor.
-# All BPKI certificate verification within rpkid
-# traces back to this trust anchor.
-#
-# @li @c rpkid-cert:
-# Name of file containing rpkid's own BPKI EE
-# certificate.
-#
-# @li @c rpkid-key:
-# Name of file containing RSA key corresponding
-# to rpkid-cert.
-#
-# @li @c irbe-cert:
-# Name of file containing BPKI certificate used
-# by IRBE when talking to rpkid.
-#
-# @li @c irdb-cert:
-# Name of file containing BPKI certificate used
-# by irdbd.
-#
-# @li @c irdb-url:
-# Service URL for irdbd. Must be a %https:// URL.
-#
-# @li @c server-host:
-# Hostname or IP address on which to listen for
-# HTTPS connections. Current default is
-# INADDR_ANY (IPv4 0.0.0.0); this will need to
-# be hacked to support IPv6 for production.
-#
-# @li @c server-port:
-# TCP port on which to listen for HTTPS
-# connections.
-#
-#
-# @section pubd pubd.py
-#
-# pubd is the publication daemon. It implements the server side of
-# the publication protocol, and is used by rpkid to publish the
-# certificates and other objects that rpkid generates.
-#
-# pubd is separate from rpkid for two reasons:
-#
-# @li The hosting model allows entities which choose to run their own
-# copies of rpkid to publish their output under a common
-# publication point. In general, encouraging shared publication
-# services where practical is a good thing for relying parties,
-# as it will speed up rcynic synchronization time.
-#
-# @li The publication server has to run on (or at least close to) the
-# publication point itself, which in turn must be on a publically
-# reachable server to be useful. rpkid, on the other hand, need
-# only be reachable by the IRBE and its children in the RPKI tree.
-# rpkid is a much more complex piece of software than pubd, so in
-# some situations it might make sense to wrap tighter firewall
-# constraints around rpkid than would be practical if rpkid and
-# pubd were a single program.
-#
-# pubd stores dynamic data in an SQL database, which must have been
-# created for it, as explained in the installation guide. pubd also
-# stores the published objects themselves as disk files in a
-# configurable location which should correspond to an appropriate
-# module definition in rsync.conf.
-#
-# The default %config file is pubd.conf, start pubd with "-c
-# filename" to choose a different %config file. ALl options are in
-# the section "[pubd]". Certifiates, keys, and trust anchors may be
-# either DER or PEM format.
-#
-# %Config file options:
-#
-# @li @c sql-username:
-# Username to hand to MySQL when connecting to
-# pubd's database.
-#
-# @li @c sql-database:
-# MySQL's database name for pubd's database.
-#
-# @li @c sql-password:
-# Password to hand to MySQL when connecting to
-# pubd's database.
-#
-# @li @c bpki-ta:
-# Name of file containing master BPKI trust
-# anchor for pubd. All BPKI validation in pubd
-# traces back to this trust anchor.
-#
-# @li @c irbe-cert:
-# Name of file containing BPKI certificate used
-# by IRBE when talking to pubd.
-#
-# @li @c pubd-cert:
-# Name of file containing BPKI certificate used
-# by pubd.
-#
-# @li @c pubd-key:
-# Name of file containing RSA key corresponding
-# to @c pubd-cert.
-#
-# @li @c server-host:
-# Hostname or IP address on which to listen for
-# HTTPS connections. Current default is
-# INADDR_ANY (IPv4 0.0.0.0); this will need to
-# be hacked to support IPv6 for production.
-#
-# @li @c server-port:
-# TCP port on which to listen for HTTPS
-# connections.
-#
-# @li @c publication-base:
-# Path to base of filesystem tree where pubd
-# should store publishable objects. Default is
-# "publication/".
-#
-#
-# @section rootd rootd.py
-#
-# rootd is a stripped down implmenetation of (only) the server side of
-# the up-down protocol. It's a separate program because the root
-# certificate of an RPKI certificate tree requires special handling and
-# may also require a special handling policy. rootd is a simple
-# implementation intended for test use, it's not suitable for use in a
-# production system. All configuration comes via the %config file.
-#
-# The default %config file is rootd.conf, start rootd with "-c filename"
-# to choose a different %config file. All options are in the section
-# "[rootd]". Certificates, keys, and trust anchors may be in either DER
-# or PEM format.
-#
-# %Config file options:
-#
-# @li @c bpki-ta:
-# Name of file containing BPKI trust anchor. All
-# BPKI certificate validation in rootd traces
-# back to this trust anchor.
-#
-# @li @c rootd-bpki-cert:
-# Name of file containing rootd's own BPKI
-# certificate.
-#
-# @li @c rootd-bpki-key:
-# Name of file containing RSA key corresponding to
-# rootd-bpki-cert.
-#
-# @li @c rootd-bpki-crl:
-# Name of file containing BPKI CRL that would
-# cover rootd-bpki-cert had it been revoked.
-#
-# @li @c child-bpki-cert:
-# Name of file containing BPKI certificate for
-# rootd's one and only child (RPKI engine to

-# to extend or rewrite irdbd.
-#
-# irdbd requires a pre-populated database to represent the IR's
-# customers. irdbd expects this database to use the SQL schema defined
-# in rpkid/irdbd.sql. Once this database has been populated, the
-# IRBE stub needs to create the appropriate objects in rpkid's database
-# via the control subset of the left-right protocol, and store the
-# linkage IDs (foreign keys into rpkid's database, basicly) in the
-# IRDB.
-#
-# irdbd's default %config file is irdbd.conf, start irdbd with "-c

-#
-# Basic configuration of irbe_cli is handled via a %config file. The

-#
-# At present the user is assumed to be able to read the (XML)
-# left-right and publication protocol messages, and with one
-# exception, irdbd-cli makes no attempt to interpret the responses
-# other than to check for signature and syntax errors. The one
-# exception is that, if the @c --pem_out option is specified on the
-# command line, any PKCS \#10 requests received from rpkid will be
-# written in PEM format to that file; this makes it easier to hand
-# these requests off to the business PKI (BPKI in order to issue signing
-# certs corresponding to newly generated business keys.
-#
-# @verbinclude irbe_cli.usage

-# @section testbed testbed.py:
-#
-# testbed is a test harness to set up and run a collection of rpkid and
-# irdbd instances under scripted control. testbed is a very recent
-# addition to the toolset and is still evolving rapidly.
-#
-# Unlike the programs described above, testbed takes two configuration
-# files in different languages. The first configuration file uses the
-# same syntax as the above configuration files but is completely
-# optional. The second configuration file is the test script, which is
-# encoded using the YAML serialization language (see
-# http://www.yaml.org/ for more information on YAML). The YAML script
-# is not optional, as it describes the test layout. testbed is designed
-# to support running a fairly wide set of test configurations as canned
-# scripts without writing any new control code. The intent is to make
-# it possible to write meaningful regression tests.
-#
-# All of the options in in the first (optional) configuration file are
-# just overrides for wired-in default values. In most cases the
-# defaults will suffice, and the set of options is still in flux, so
-# only a few of the options are described here. The default name for
-# this configuration file is testbed.conf, run testbed with "-c
-# filename" to change it.
-#
-# testbed.conf options:
-#
-# @li @c testbed_dir:
-# Working directory into which testbed should write the
-# (many) files it generates. Default is "testbed.dir".
-#
-# @li @c irdb_db_pass:
-# MySQL password for the "irdb" user. Default is
-# "fnord". You may want to override this.
-#
-# @li @c rpki_db_pass:
-# MySQL password for the "rpki" user. Default is
-# "fnord". You may want to override this.
-#
-# @li @c rootd_sia:
-# rsync URI naming a (perhaps fictious) directory to use
-# as the id-ad-caRepository SIA value in the generated
-# root resource certificate. Default is
-# "rsync://wombat.invalid/". You may want to override
-# this if you intend to run an rsync server and test
-# against the generated results using rcynic. This
-# default will likely change if and when testbed learns
-# how to run rcynic itself as part of the test suite.
-#
-# The second configuration file is named testbed.yaml by default, run
-# testbed with "-y filename" to change it. The YAML file contains
-# multiple YAML "documents". The first document describes the initial
-# test layout and resource allocations, subsequent documents describe
-# modifications to the initial allocations and other parameters.
-# Resources listed in the initial layout are aggregated automatically,
-# so that a node in the resource hierarchy automatically receives the
-# resources it needs to issue whatever its children are listed as
-# holding. Actions in the subsequent documents are modifications to the
-# current resource set, modifications to validity dates or other
-# non-resource parameters, or special commands like "sleep". The
-# details are still evolving, but here's an example of current usage:
-#
-# @verbatim
-# name: RIR
-# valid_for: 2d
-# sia_base: "rsync://wombat.invalid/"
-# kids:
-# - name: LIR0
-# kids:
-# - name: Alice
-# ipv4: 192.0.2.1-192.0.2.33
-# asn: 64533
-# ---
-# - name: Alice
-# valid_add: 10
-# ---
-# - name: Alice
-# add_as: 33
-# valid_add: 2d
-# ---
-# - name: Alice
-# valid_sub: 2d
-# ---
-# - name: Alice
-# valid_for: 10d
-# @endverbatim
-#
-# This specifies an initial layout consisting of an RPKI engine named
-# "RIR", with one child "LIR0", which in turn has one child "Alice".
-# Alice has a set of assigned resources, and all resources in the system
-# are initially set to be valid for two days from the time at which the
-# test is started. The first subsequent document adds ten seconds to
-# the validity interval for Alice's resources and makes no other
-# modifications. The second subsequent document grants Alice additional
-# resources and adds another two days to the validity interval for
-# Alice's resources. The next document subtracts two days from the
-# validity interval for Alice's resources. The final document sets the
-# validity interval for Alice's resources to ten days.
-#
-# Operators in subsequent (update) documents:
-#
-# @li @c add_as, @c add_v4, @c add_v6:
-# These add ASN, IPv4, or IPv6 resources, respectively.
-#
-# @li @c sub_as, @c sub_v4, @c sub_v6:
-# These subtract resources.
-#
-# @li @c valid_until:
-# Set an absolute expiration date.
-#
-# @li @c valid_for:
-# Set a relative expiration date.
-#
-# @li @c valid_add, @c valid_sub:
-# Add to or subtract from validity interval.
-#
-# @li @c sleep [interval]:
-# Sleep for specified interval, or until testbed receives a SIGALRM signal.
-#
-# Absolute timestamps should be in the form shown (UTC timestamp format
-# as used in XML).
-#
-# Intervals (@c valid_add, @c valid_sub, @c valid_for, @c sleep) are either
-# integers, in which case they're interpreted as seconds, or are a
-# string of the form "wD xH yM zS" where w, x, y, and z are integers and
-# D, H, M, and S indicate days, hours, minutes, and seconds. In the
-# latter case all of the fields are optional, but at least one must be
-# specified. For example, "3D4H" means "three days plus four hours".
-#
-#
-# @section testpoke testpoke.py
-#
-# This is a command-line client for the up-down protocol. Unlike all of
-# the above programs, testpoke does not accept a %config file in
-# OpenSSL-compatable format at all. Instead, it is configured
-# exclusively by a YAML script. testpoke's design was constrained by a
-# desire to have it be compatable with APNIC's rpki_poke.pl tool, so
-# that the two tools could use a common configuration language to
-# simplify scripted testing. There are minor variations due to slightly
-# different feature sets, but YAML files intended for one program will
-# usually work with the other.

-## @page Left-right Left-right protocol
-#
-# The left-right protocol is really two separate client/server
-# protocols over separate channels between the RPKI engine and the IR
-# back end (IRBE). The IRBE is the client for one of the
-# subprotocols, the RPKI engine is the client for the other.
-#

-#
-# @section Operations initiated by the IRBE
-#
-# This part of the protcol uses a kind of message-passing. Each %object
-# that the RPKI engine knows about takes five messages: "create", "set",
-# "get", "list", and "destroy". Actions which are not just data
-# operations on %objects are handled via an SNMP-like mechanism, as if
-# they were fields to be set. For example, to generate a keypair one
-# "sets" the "generate-keypair" field of a BSC %object, even though there
-# is no such field in the %object itself as stored in SQL. This is a bit
-# of a kludge, but the reason for doing it as if these were variables
-# being set is to allow composite operations such as creating a BSC,
-# populating all of its data fields, and generating a keypair, all as a
-# single operation. With this model, that's trivial, otherwise it's at
-# least two round trips.
-#
-# Fields can be set in either "create" or "set" operations, the
-# difference just being whether the %object already exists. A "get"
-# operation returns all visible fields of the %object. A "list"
-# operation returns a %list containing what "get" would have returned on
-# each of those %objects.
-#
-# Left-right protocol %objects are encoded as signed CMS messages
-# containing XML as eContent and using an eContentType OID of @c id-ct-xml
-# (1.2.840.113549.1.9.16.1.28). These CMS messages are in turn passed
-# as the data for HTTPS POST operations, with an HTTP content type of
-# "application/x-rpki" for both the POST data and the response data.
-#
-# All operations allow an optional "tag" attribute which can be any
-# alphanumeric token. The main purpose of the tag attribute is to allow
-# batching of multiple requests into a single PDU.
-#
-# @subsection self_obj <self/> object
-#
-# A @c &lt;self/&gt; %object represents one virtual RPKI engine. In simple cases
-# where the RPKI engine operator operates the engine only on their own
-# behalf, there will only be one @c &lt;self/&gt; %object, representing the engine
-# operator's organization, but in environments where the engine operator
-# hosts other entities, there will be one @c @c &lt;self/&gt; %object per hosted
-# entity (probably including the engine operator's own organization,
-# considered as a hosted customer of itself).
-#
-# Some of the RPKI engine's configured parameters and data are shared by
-# all hosted entities, but most are tied to a specific @c &lt;self/&gt; %object.
-# Data which are shared by all hosted entities are referred to as
-# "per-engine" data, data which are specific to a particular @c &lt;self/&gt;
-# %object are "per-self" data.
-#
-# Since all other RPKI engine %objects refer to a @c &lt;self/&gt; %object via a
-# "self_handle" value, one must create a @c &lt;self/&gt; %object before one can
-# usefully configure any other left-right protocol %objects.
-#
-# Every @c &lt;self/&gt; %object has a self_handle attribute, which must be specified
-# for the "create", "set", "get", and "destroy" actions.
-#
-# Payload data which can be configured in a @c &lt;self/&gt; %object:
-#
-# @li @c use_hsm (attribute):
-# Whether to use a Hardware Signing Module. At present this option
-# has no effect, as the implementation does not yet support HSMs.
-#
-# @li @c crl_interval (attribute):
-# Positive integer representing the planned lifetime of an RPKI CRL
-# for this @c &lt;self/&gt;, measured in seconds.
-#
-# @li @c regen_margin (attribute):
-# Positive integer representing how long before expiration of an
-# RPKI certificiate a new one should be generated, measured in
-# seconds. At present this only affects the one-off EE certificates
-# associated with ROAs.
-#
-# @li @c bpki_cert (element):
-# BPKI CA certificate for this @c &lt;self/&gt;. This is used as part of the
-# certificate chain when validating incoming TLS and CMS messages,
-# and should be the issuer of cross-certification BPKI certificates
-# used in @c &lt;repository/&gt;, @c &lt;parent/&gt;, and @c &lt;child/&gt; %objects. If the
-# bpki_glue certificate is in use (below), the bpki_cert certificate
-# should be issued by the bpki_glue certificate; otherwise, the
-# bpki_cert certificate should be issued by the per-engine bpki_ta
-# certificate.
-#
-# @li @c bpki_glue (element):
-# Another BPKI CA certificate for this @c &lt;self/&gt;, usually not needed.
-# Certain pathological cross-certification cases require a
-# two-certificate chain due to issuer name conflicts. If used, the
-# bpki_glue certificate should be the issuer of the bpki_cert
-# certificate and should be issued by the per-engine bpki_ta
-# certificate; if not needed, the bpki_glue certificate should be
-# left unset.
-#
-# Control attributes that can be set to "yes" to force actions:
-#
-# @li @c rekey:
-# Start a key rollover for every RPKI CA associated with every
-# @c &lt;parent/&gt; %object associated with this @c &lt;self/&gt; %object. This is the
-# first phase of a key rollover operation.
-#
-# @li @c revoke:
-# Revoke any remaining certificates for any expired key associated
-# with any RPKI CA for any @c &lt;parent/&gt; %object associated with this
-# @c &lt;self/&gt; %object. This is the second (cleanup) phase for a key
-# rollover operation; it's separate from the first phase to leave
-# time for new RPKI certificates to propegate and be installed.
-#
-# @li @c reissue:
-# Not implemented, may be removed from protocol. Original theory
-# was that this operation would force reissuance of any %object with
-# a changed key, but as that happens automatically as part of the
-# key rollover mechanism this operation seems unnecessary.
-#
-# @li @c run_now:
-# Force immediate processing for all tasks associated with this
-# @c &lt;self/&gt; %object that would ordinarily be performed under cron. Not
-# currently implemented.
-#
-# @li @c publish_world_now:
-# Force (re)publication of every publishable %object for this @c &lt;self/&gt;
-# %object. Not currently implemented. Intended to aid in recovery
-# if RPKI engine and publication engine somehow get out of sync.
-#
-#
-# @subsection bsc_obj <bsc/> object
-#
-# The @c &lt;bsc/&gt; ("business signing context") %object represents all the BPKI
-# data needed to sign outgoing CMS or HTTPS messages. Various other
-# %objects include pointers to a @c &lt;bsc/&gt; %object. Whether a particular
-# @c &lt;self/&gt; uses only one @c &lt;bsc/&gt; or multiple is a configuration decision
-# based on external requirements: the RPKI engine code doesn't care, it
-# just cares that, for any %object representing a relationship for which
-# it must sign messages, there be a @c &lt;bsc/&gt; %object that it can use to
-# produce that signature.
-#
-# Every @c &lt;bsc/&gt; %object has a bsc_handle, which must be specified for the
-# "create", "get", "set", and "destroy" actions. Every @c &lt;bsc/&gt; also has a self_handle
-# attribute which indicates the @c &lt;self/&gt; %object with which this @c &lt;bsc/&gt;
-# %object is associated.
-#
-# Payload data which can be configured in a @c &lt;isc/&gt; %object:
-#
-# @li @c signing_cert (element):
-# BPKI certificate to use when generating a signature.
-#
-# @li @c signing_cert_crl (element):
-# CRL which would %list signing_cert if it had been revoked.
-#
-# Control attributes that can be set to "yes" to force actions:
-#
-# @li @c generate_keypair:
-# Generate a new BPKI keypair and return a PKCS #10 certificate
-# request. The resulting certificate, once issued, should be
-# configured as this @c &lt;bsc/&gt; %object's signing_cert.
-#
-# Additional attributes which may be specified when specifying
-# "generate_keypair":
-#
-# @li @c key_type:

-#
-# The @c &lt;parent/&gt; %object represents the RPKI engine's view of a particular

-#
-# Every @c &lt;parent/&gt; %object has a parent_handle, which must be specified for
-# the "create", "get", "set", and "destroy" actions. Every @c &lt;parent/&gt; also has a

-#
-# @subsection route_origin_obj <route_origin/> object
-#
-# This section is out-of-date. The @c &lt;route_origin/&gt; %object
-# has been replaced by the @c &lt;list_roa_requests/&gt; IRDB query,
-# but the documentation for that hasn't been written yet.
-#
-# The @c &lt;route_origin/&gt; %object is a kind of prototype for a ROA. It
-# contains all the information needed to generate a ROA once the RPKI
-# engine obtains the appropriate RPKI certificates from its parent(s).
-#
-# Note that a @c &lt;route_origin/&gt; %object represents a ROA to be generated on
-# behalf of @c &lt;self/&gt;, not on behalf of a @c &lt;child/&gt;. Thus, a hosted entity
-# that has no children but which does need to generate ROAs would be
-# represented by a hosted @c &lt;self/&gt; with no @c &lt;child/&gt; %objects but one or
-# more @c &lt;route_origin/&gt; %objects. While lumping ROA generation in with
-# the other RPKI engine activities may seem a little odd at first, it's
-# a natural consequence of the design requirement that the RPKI daemon
-# never transmit private keys across the network in any form; given this
-# requirement, the RPKI engine that holds the private keys for an RPKI
-# certificate must also be the engine which generates any ROAs that
-# derive from that RPKI certificate.
-#
-# The precise content of the @c &lt;route_origin/&gt; has changed over time as
-# the underlying ROA specification has changed. The current
-# implementation as of this writing matches what we expect to see in
-# draft-ietf-sidr-roa-format-03, once it is issued. In particular, note
-# that the exactMatch boolean from the -02 draft has been replaced by
-# the prefix and maxLength encoding used in the -03 draft.
-#
-# Payload data which can be configured in a @c &lt;route_origin/&gt; %object:
-#
-# @li @c asn (attribute):
-# Autonomous System Number (ASN) to place in the generated ROA. A
-# single ROA can only grant authorization to a single ASN; multiple
-# ASNs require multiple ROAs, thus multiple @c &lt;route_origin/&gt; %objects.
-#
-# @li @c ipv4 (attribute):
-# %List of IPv4 prefix and maxLength values, see below for format.
-#
-# @li @c ipv6 (attribute):
-# %List of IPv6 prefix and maxLength values, see below for format.
-#
-# Control attributes that can be set to "yes" to force actions:
-#
-# @li @c suppress_publication:
-# Not implemented, may be removed from protocol.
-#
-# The lists of IPv4 and IPv6 prefix and maxLength values are represented
-# as comma-separated text strings, with no whitespace permitted. Each
-# entry in such a string represents a single prefix/maxLength pair.
-#
-# ABNF for these address lists:
-#
-# @verbatim
-#
-# <ROAIPAddress> ::= <address> "/" <prefixlen> [ "-" <max_prefixlen> ]
-# ; Where <max_prefixlen> defaults to the same
-# ; value as <prefixlen>.
-#
-# <ROAIPAddressList> ::= <ROAIPAddress> *( "," <ROAIPAddress> )
-#
-# @endverbatim
-#
-# For example, @c "10.0.1.0/24-32,10.0.2.0/24", which is a shorthand
-# form of @c "10.0.1.0/24-32,10.0.2.0/24-24".
-#
-# @section irdb_queries Operations initiated by the RPKI engine
-#
-# The left-right protocol also includes queries from the RPKI engine
-# back to the IRDB. These queries do not follow the message-passing
-# pattern used in the IRBE-initiated part of the protocol. Instead,
-# there's a single query back to the IRDB, with a corresponding
-# response. The CMS and HTTPS encoding are the same as in the rest of
-# the protocol, but the BPKI certificates will be different as the
-# back-queries and responses form a separate communication channel.
-#
-# @subsection list_resources_msg <list_resources/> messages
-#
-# The @c &lt;list_resources/&gt; query and response allow the RPKI engine to ask
-# the IRDB for information about resources assigned to a particular
-# child. The query must include both a @c "self_handle" attribute naming
-# the @c &lt;self/&gt; that is making the request and also a @c "child_handle"
-# attribute naming the child that is the subject of the query. The
-# query and response also allow an optional @c "tag" attribute of the
-# same form used elsewhere in this protocol, to allow batching.
-#
-# A @c &lt;list_resources/&gt; response includes the following attributes, along
-# with the @c tag (if specified), @c self_handle, and @c child_handle copied
-# from the request:
-#
-# @li @c valid_until:
-# A timestamp indicating the date and time at which certificates
-# generated by the RPKI engine for these data should expire. The
-# timestamp is expressed as an XML @c xsd:dateTime, must be
-# expressed in UTC, and must carry the "Z" suffix indicating UTC.
-#
-# @li @c asn:
-# A %list of autonomous sequence numbers, expressed as a
-# comma-separated sequence of decimal integers with no whitespace.
-#
-# @li @c ipv4:
-# A %list of IPv4 address prefixes and ranges, expressed as a
-# comma-separated %list of prefixes and ranges with no whitespace.
-# See below for format details.
-#
-# @li @c ipv6:
-# A %list of IPv6 address prefixes and ranges, expressed as a
-# comma-separated %list of prefixes and ranges with no whitespace.
-# See below for format details.
-#
-# Entries in a %list of address prefixes and ranges can be either
-# prefixes, which are written in the usual address/prefixlen notation,
-# or ranges, which are expressed as a pair of addresses denoting the
-# beginning and end of the range, written in ascending order separated
-# by a single "-" character. This format is superficially similar to
-# the format used for prefix and maxLength values in the @c &lt;route_origin/&gt;
-# %object, but the semantics differ: note in particular that
-# @c &lt;route_origin/&gt; %objects don't allow ranges, while @c &lt;list_resources/&gt;
-# messages don't allow a maxLength specification.
-#
-# @section left_right_error_handling Error handling
-#
-# Error in this protocol are handled at two levels.
-#
-# Since all messages in this protocol are conveyed over HTTPS
-# connections, basic errors are indicated via the HTTP response code.
-# 4xx and 5xx responses indicate that something bad happened. Errors
-# that make it impossible to decode a query or encode a response are
-# handled in this way.
-#
-# Where possible, errors will result in a @c &lt;report_error/&gt; message which
-# takes the place of the expected protocol response message.
-# @c &lt;report_error/&gt; messages are CMS-signed XML messages like the rest of
-# this protocol, and thus can be archived to provide an audit trail.
-#
-# @c &lt;report_error/&gt; messages only appear in replies, never in queries.
-# The @c &lt;report_error/&gt; message can appear on either the "forward" (IRBE
-# as client of RPKI engine) or "back" (RPKI engine as client of IRDB)
-# communication channel.
-#
-# The @c &lt;report_error/&gt; message includes an optional @c "tag" attribute to
-# assist in matching the error with a particular query when using
-# batching, and also includes a @c "self_handle" attribute indicating the
-# @c &lt;self/&gt; that issued the error.
-#
-# The error itself is conveyed in the @c error_code (attribute). The
-# value of this attribute is a token indicating the specific error that
-# occurred. At present this will be the name of a Python exception; the
-# production version of this protocol will nail down the allowed error
-# tokens here, probably in the RelaxNG schema.
-#
-# The body of the @c &lt;report_error/&gt; element itself is an optional text
-# string; if present, this is debugging information. At present this
-# capabilty is not used, debugging information goes to syslog.

-## @page Publication Publication protocol
-#
-# The %publication protocol is really two separate client/server
-# protocols, between different parties. The first is a configuration
-# protocol for an IRBE to use to configure a %publication engine,
-# the second is the interface by which authorized clients request
-# %publication of specific objects.
-#
-# Much of the architecture of the %publication protocol is borrowed
-# from the @link Left-right left-right protocol: @endlink like the
-# left-right protocol, the %publication protocol uses CMS-wrapped XML
-# over HTTPS with the same eContentType OID and the same HTTPS
-# content-type, and the overall style of the XML messages is very
-# similar to the left-right protocol. All operations allow an
-# optional "tag" attribute to allow batching.
-#
-# The %publication engine operates a single HTTPS server which serves
-# both of these subprotocols. The two subprotocols share a single
-# server port, but use distinct URLs to allow demultiplexing.

-# @section Publication-control Publication control subprotocol
-#
-# The control subprotocol reuses the message-passing design of the
-# left-right protocol. Configured objects support the "create", "set",
-# "get", "list", and "destroy" actions, or a subset thereof when the
-# full set of actions doesn't make sense.
-#
-# @subsection config_obj <config/> object
-#
-# The &lt;config/&gt; %object allows configuration of data that apply to the
-# entire %publication server rather than a particular client.
-#
-# There is exactly one &lt;config/&gt; %object in the %publication server, and
-# it only supports the "set" and "get" actions -- it cannot be created
-# or destroyed.
-#
-# Payload data which can be configured in a &lt;config/&gt; %object:
-#
-# @li @c bpki_crl (element):
-# This is the BPKI CRL used by the %publication server when
-# signing the CMS wrapper on responses in the %publication
-# subprotocol. As the CRL must be updated at regular intervals,
-# it's not practical to restart the %publication server when the
-# BPKI CRL needs to be updated. The BPKI model doesn't require
-# use of a BPKI CRL between the IRBE and the %publication server,
-# so we can use the %publication control subprotocol to update the
-# BPKI CRL.
-#
-# @subsection client_obj <client/> object
-#
-# The &lt;client/&gt; %object represents one client authorized to use the
-# %publication server.
-#
-# The &lt;client/&gt; %object supports the full set of "create", "set", "get",
-# "list", and "destroy" actions. Each client has a "client_handle"
-# attribute, which is used in responses and must be specified in "create", "set",
-# "get", or "destroy" actions.
-#
-# Payload data which can be configured in a &lt;client/&gt; %object:
-#
-# @li @c base_uri (attribute):
-# This is the base URI below which this client is allowed to publish
-# data. The %publication server may impose additional constraints in
-# the case of a child publishing beneath its parent.
-#
-# @li @c bpki_cert (element):
-# BPKI CA certificate for this &lt;client/&gt;. This is used as part of
-# the certificate chain when validating incoming TLS and CMS
-# messages. If the bpki_glue certificate is in use (below), the
-# bpki_cert certificate should be issued by the bpki_glue
-# certificate; otherwise, the bpki_cert certificate should be issued
-# by the %publication engine's bpki_ta certificate.
-#
-# @li @c bpki_glue (element):
-# Another BPKI CA certificate for this &lt;client/&gt;, usually not
-# needed. Certain pathological cross-certification cases require a
-# two-certificate chain due to issuer name conflicts. If used, the
-# bpki_glue certificate should be the issuer of the bpki_cert
-# certificate and should be issued by the %publication engine's
-# bpki_ta certificate; if not needed, the bpki_glue certificate
-# should be left unset.
-#
-# @section Publication-publication Publication subprotocol
-#
-# The %publication subprotocol is structured somewhat differently from
-# the %publication control protocol. Objects in the %publication
-# subprotocol represent objects to be published or objects to be
-# withdrawn from %publication. Each kind of %object supports two actions:
-# "publish" and "withdraw". In each case the XML element representing
-# hte %object to be published or withdrawn has a "uri" attribute which
-# contains the %publication URI. For "publish" actions, the XML element
-# body contains the DER %object to be published, encoded in Base64; for
-# "withdraw" actions, the XML element body is empty.
-#
-# In theory, the detailed access control for each kind of %object might
-# be different. In practice, as of this writing, access control for all
-# objects is a simple check that the client's @c "base_uri" is a leading
-# substring of the %publication URI. Details of why access control might
-# need to become more complicated are discussed in a later section.
-#
-# @subsection certificate_obj <certificate/> object

-# @subsection manifest_obj <manifest/> object
-#
-# The &lt;manifest/&gt; %object represents an RPKI %publication %manifest to be
-# published or withdrawn.
-#
-# Note that part of the reason for the batching support in the
-# %publication protocol is because @em every %publication or withdrawal
-# action requires a new %manifest, thus every %publication or withdrawal
-# action will involve at least two objects.

-# @subsection roa_obj <roa/> object

-# string; if present, this is debugging information. At present this
-# capabilty is not used, debugging information goes to syslog.
-#
-# @section publication_access_control Additional access control considerations.
-#
-# As detailed above, the %publication protocol is trivially simple. This
-# glosses over two bits of potential complexity:
-#
-# @li In the case where parent and child are sharing a repository, we'd
-# like to nest child under parent, because testing has demonstrated
-# that even on relatively slow hardware the delays involved in
-# setting up separate rsync connections tend to dominate
-# synchronization time for relying parties.
-#
-# @li The repository operator might also want to do some checks to
-# assure itself that what it's about to allow the RPKI engine to
-# publish is not dangerous toxic waste.
-#
-# The up-down protocol includes a mechanism by which a parent can
-# suggest a %publication URI to each of its children. The children are
-# not required to accept this hint, and the children must make separate
-# arrangements with the repository operator (who might or might not be
-# the same as the entity that hosts the children's RPKI engine
-# operations) to use the suggested %publication point, but if everything
-# works out, this allows children to nest cleanly under their parents
-# %publication points, which helps reduce synchronization time for
-# relying parties.
-#
-# In this case, one could argue that the %publication server is
-# responsible for preventing one of its clients (the child in the above
-# description) from stomping on data published by another of its clients
-# (the parent in the above description). This goes beyond the basic
-# access check and requires the %publication server to determine whether
-# the parent has given its consent for the child to publish under the
-# parent. Since the RPKI certificate profile requires the child's
-# %publication point to be indicated in an SIA extension in a certificate
-# issued by the parent to the child, the %publication engine can infer
-# this permission from the parent's issuance of a certificate to the
-# child. Since, by definition, the parent also uses this %publication
-# server, this is an easy check, as the %publication server should
-# already have the parent's certificate available by the time it needs
-# to check the child's certificate.
-#
-# The previous paragraph only covers a "publish" action for a
-# &lt;certificate/&gt; %object. For "publish" actions on other
-# objects, the %publication server would need to trace permission back
-# to the certificate issued by the parent; for "withdraw" actions,
-# the %publication server would have to perform the same checks it
-# would perform for a "publish" action, using the current published

-## @page bpki-model BPKI model
-#
-# The "business PKI" (BPKI) is the PKI used to authenticate
-# communication on the up-down, left-right, and %publication protocols.
-# BPKI certificates are @em not resource PKI (RPKI) certificates. The
-# BPKI is a separate PKI that represents relationships between the
-# various entities involved in the production side of the RPKI system.
-# In most cases the BPKI tree will follow existing business
-# relationships, hence the name "BPKI".
-#
-# Setup of the BPKI is handled by the back end; for the most part,
-# rpkid and pubd just use the result. The one place where the engines
-# are directly involved in creation of new BPKI certificates is in the
-# production of end-entity certificates for use by the engines.
-#
-# There are a few design principals that underly the chosen BPKI model:
-# @li Each engine should rely on a single BPKI trust anchor which is
-# controlled by the back end entity that runs the engine; all
-# other trust material should be cross-certified into the engine's
-# BPKI tree.
-# @li Private keys must never transit the network.
-# @li Except for end entity certificates, the engine should only have
-# access to the BPKI certificates; in particular, the private key
-# for the BPKI trust anchor should not be accessible to the engine.
-# @li The number of BPKI keys and certificates that the engine has to
-# manage should be no larger than is necessary.
-#
-# rpkid's hosting model adds an additional constraint: rpkid's BPKI
-# trust anchor belongs to the entity operating rpkid, but the entities
-# hosted by rpkid should have control of their own BPKI private keys.
-# This implies the need for an additional layer of BPKI certificate
-# hierarchy within rpkid.
-#
-# Here is a simplified picture of what the BPKI might look like for an
-# rpkid operator that hosts two entities, "Alice" and "Ellen":

-# There's one nasty bit where the model had to bend to fit the current
-# state of the underlying protocols: it's not possible to use exactly
-# the same BPKI keys and certificates for HTTPS and CMS. The reason
-# for this is simple: each hosted entity has its own BPKI, as does the
-# hosting entity, but the HTTPS listener is shared. The only ways to
-# avoid sharing the HTTPS server certificate would be to use separate
-# listeners for each hosted entity, which scales poorly, or to rely on
-# the TLS "Server Name Indication" extension (RFC 4366 3.1) which is
-# not yet widely implemented.
-#
-# The certificate tree looks complicated, but the set of certificates
-# needed to build any particular validation chain is obvious, again
-# excepting the HTTPS server case, where the client certificate is the
-# first hint that the engine has of the client's identity, so the
-# server must be prepared to accept any current client certificate.
-#
-# Detailed instructions on how to build a BPKI are beyond the scope of
-# this document, but one can handle simple cases using the OpenSSL
-# command line tool and cross_certify.py; the latter is a tool
-# designed specifically for the purpose of generating the
-# cross-certification certificates needed to splice foreign trust
-# material into a BPKI tree.
-#
-# The BPKI tree for a pubd instance is similar to to the BPKI tree for
-# an rpkid instance, but is a bit simpler, as pubd does not provide
-# hosting in the same sense that rpkid does: pubd is a relatively
-# simple server that publishes objects as instructed by its clients.

-# While it is likely that RIRs (at least) will operate both rpkid and
-# pubd instances, the two functions are conceptually separate. As far
-# as pubd is concerned, it doesn't matter who operates the rpkid
-# instance: pubd just has clients, each of which has trust material
-# that has been cross-certified into pubd's BPKI. Similarly, rpkid
-# doesn't really care who operates a pubd instance that it's been
-# configured to use, it just treats that pubd as a foreign BPKI whose
-# trust material has to be cross-certified into its own BPKI. Cross
-# certification itself is done by the back end operator, using
-# cross_certify or some equivalent tool; the resulting BPKI
-# certificates are configured into rpkid and pubd via the left-right
-# protocol and the control subprotocol of the publication protocol,
-# respectively.
-#
-# Because the BPKI tree is almost entirely controlled by the operating
-# entity, CRLs are not necessary for most of the BPKI. The one
-# exception to this is the EE certificates issued under the
-# cross-certification points. These EE certificates are generated by
-# the peer, not the local operator, and thus require CRLs. Because of
-# this, both rpkid and pubd require regular updates of certain BPKI
-# CRLs, again via the left-right and publication control protocols.
-#
-# Because the left-right protocol and the publication control
-# subprotocol are used to configure BPKI certificates and CRLs, they
-# cannot themselves use certificates and CRLs configured in this way.
-# This is why the configuration files for rpkid and pubd require
-# static configuration of the left-right and publication control
-# certificates.
