Andreas, Regarding Java S/MIME, check out http://www.bouncycastle.org/, which claims, Generators for S/MIME and CMS (PKCS7). I have used Bouncy Castle's crypto APIs, but not their S/MIME APIs, so I am not sure about the details of their S/MIME APIs and whether they will satisfy your needs.

Have you used the following functions to register OpenSSL thread-safety callbacks: CRYPTO_set_locking_callback(locking_function); CRYPTO_set_id_callback(id_function); You need to supply your own locking_function() and id_function(), samples of which can be found in OpenSSL's
