Hi Folks,
Please forgive me if this question is a little thick.
I understand that S/MIME v1 can't support DSA keys because it requires
the messageDigest, which DSA does not provide. And if authenticated
attributes are present, the messageDigest attribute (among others) MUST
be present.
Would some kind soul please tell me if S/MIME v2 gets away from this
somehow and therefore allows DSA keys, or do we have to wait for S/MIME
v3?
I can't really tell much difference between S/MIME v1 and v2 in terms of
ASN.1 except for the application/mime types. Do I have this right
[broad strokes]:
v1 - RSA developed this
v2 - continuation of v1, only under IETF
v3 - DSA, signed receipts, security clearance, MLA's
Mainly what I'm jonesin' for is DSA; the other stuff can wait for my
purposes, for the moment.
Thanks in advance,
