Please take a look at RFCs 3369, 3370, 2632, 2633, and 2634. You will see
that ASN.1 is used for certificates and PKCS#7 (which we call CMS).
Signatures generally cover the MEME-encoded content as well as signed
attributes. Each of the these attributes is specified in ASN.1.

My company is evaluating a number of options for deployment of AS2 in our
product. In one of our evaluation meetings, it was said that care must be
taken when choosing the correct S/MIME toolkit because of the dependence
that S/MIME has on ASN.1 and the complications that introduces.
I can accept that certificates and related cryptographic materials are DER
or BER encoded but I would expect that to be done by a cryptographic
toolkit from RSA, Baltimore Technologies, Certicom, etc. I would not
expect this to be value added by an S/MIME toolkit.
Beyond the PKCS standards, where does S/MIME utilize ASN.1?
Specific to AS2, are there other parts of that spec that call for ASN.1?
Thank you; Phil Smiley
