IA5 String...

There was a lot of energy around S/MIME. People are implementing it. Internally, it's pretty kludgely, but it does provide pretty good cryptographic services. (as an aside, my favorite kludge anecdote is the fact that X.509 certificates use an IA5 character set rather than ASCII, so that the @ in email addresses has to be represented as (a) instead).

Wow, is this true? I dont think so. The CCITT document I have (CCITT T.50) mentions that an @ sign (Commercial at) is a member of the IRV.

From what I understand IA5 basically means US ASCII.
