Renato,

RFC 2459 contains two complete ASN.1 definitions:

one in 1988 syntax (beginning on page 69), and
one in 1993 syntax (beginning on page 90)

X.509 uses the 1993 syntax.

I BELIEVE that the IETF and X5 are committed to aligning both documents.

RFC 2459 has one obvious advantage over X.509. RFC 2459 is free.

Frank
