comment openssl verify signature
Right, so you agree with what I said in previous comment: it's not "sign message digest" as you used in your answer, it's just "sign message" as "sign message digest" would imply "encrypt digest of message digest" :) anyway, the above commands do not output PKCS7 objects, just plain signature. I was hoping command line openssl tool would be able to the PKCS7_sign that the (openssl) library provides openssl.org/docs/crypto/PKCS7_sign.html but it seems it can't...

One other question, on pure terminology, you say "sign a message digest", but it is "encrypt message digest" or "sign message" right? As signing is basically encrypting an hash, as far I as understand.

comment openssl verify signature
Thanks Zedman, but I meant signing into a PKCS#7 object just like smime option does (and verifying from a PKCS#7 public key certificate as well). I'll add this to the question to become more explicit.
