Abstract Syntax Notation 1 (ASN1) is probably one of the worst encodings the Internet community has seen. Unfortunately this encoding is a key component in Internet security. Peter Gutmann, professor at the University of Auckland, NZ has not just written “How Not to Design a Crypto Protocol/Standard“, but also an ASN1-dump C-program. I added a Java-script port written by Lapo Luchini to my homepage under http://www.zlabinger.at/asn1dump.
This version uses the top certificate of the TKK as an example.
