This +# has gotten silly, but we haven't yet refactored the current packaged +# builds from two packages into three (adding a -libs package). +# +# So, by rights, this program should be a C monstrosity written using +# the OpenSSL C API. I started coding it that way, but it was just +# too painful for something we're probably going to rewrite as a few +# lines of Python once we refactor, but by the same token I didn't +# want to delay router certificate support until the refactoring. +# +# So this program anticipates the new scheme of things, but makes one +# concession to current reality: if it has a problem importing the +# RPKI-specific libraries, it just quietly exits as if everything were +# fine and there simply are no router certificates to report. This +# isn't the right answer in the long run, but will suffice to avoid +# further bald yaks. + +import os +import sys +import base64 + +try: + import rpki.POW + import rpki.oids +except ImportError: + sys.exit(0) + +rcynic_dir = sys.argv[1] + +for root, dirs, files in os.walk(rcynic_dir): + for fn in files: + if not fn.endswith(".cer"): + continue + x = rpki.POW.X509.derReadFile(os.path.join(root, fn)) + + if rpki.oids.id_kp_bgpsec_router not in (x.getEKU() or ()): + continue + + sys.stdout.write(base64.urlsafe_b64encode(x.getSKI()).rstrip("=")) + for min_asn, max_asn in x.getRFC3779()[0]: + for asn in xrange(min_asn, max_asn + 1): + sys.stdout.write(" %s" % asn) + sys.stdout.write(" %s\n" % base64.b64encode(x.getPublicKey().derWritePublic())) |
