# The RPKI Out-Of-Band Setup Protocol

This protocol configures the initial URLs and BPKI certificates needed to
operate the up-down and publication protocols. This is not an IETF standard of
any kind. The rpki.net code is, as far as we know, the only complete
implementation of this protocol, but other RPKI CA packages implement portions
of it for interoperability.

In the long run we intend to clean this up and submit the cleaned-up version
as a candidate for IETF standardization, since it seems to be in everyone's
best interests, but we're not there yet.
