This is in reference to flex code I posted in my last mail.

I have written an ASN 1 Parser for DER encoded certificates in C.
Currently, the parser reads in DER encoded file from standard input and
outputs a human readable text heirarchy on standard output.

The source and executable are at:

The limitations:
a) Object Identifiers are not well supported (As I dont understand how they
are parsed)

To be done:
a) add better support for Object Identifiers
b) convert executable to library
c) add support to parse ASN1 to XML
d) build X509 API over this API to support higher level calls.

With Warm Regards
