Depends on what you mean by "PKCS7 handling" if you just mean being able to
parse PKCS#7 structures then even SSLeay would handle it. If you mean S/MIME
then it first appeared in 0.9.5 but there have been *many* security and
bugfixing changes since then.

You might be able to use CryptoAPI if the necessary PKCS#7 support was
present: not sure if it was.
