For those who are interested, I¹ve pushed an ASN.1 codec API sufficient for Kerberos parsing to nrmk/include/codec/asn.1. The unit-test is in nrmk/lib/codec/asn.1/test if you want to see how it can be used. I¹ll be working on the Kerberos 5 codec next leveraging the BER/DER APIs, so be patient with me. :) Jeff
