Some developers would like the IETF to use the latest version of ASN.1 in its standards. Most of the RFCs that relate to security protocols still use ASN.1 from the 1988 standard, which has been deprecated. This is particularly true for the standards that relate to PKIX, Cryptographic Message Syntax (CMS), and S/MIME.

  New ASN.1 Modules for the Public Key Infrastructure Using X.509 (PKIX)


   The Public Key Infrastructure using X.509 (PKIX) certificate format,    and many associated formats, are expressed using ASN.1.  The current    ASN.1 modules conform to the 1988 version of ASN.1.  This document    updates those ASN.1 modules to conform to the 2002 version of ASN.1.    There are no bits-on-the-wire changes to any of the formats; this is    simply a change to the syntax.
