OpenSSL currently supports PKCS#7 which is used in S/MIME v2. There are some PKCS#7 forms (encrypted data content type) that just use symmetric keys, typically derived from passwords. OpenSSL supports those but primarily for use in PKCS#12. CMS and S/MIME v3 support is planned for some future version of OpenSSL. Steve. -- Dr Stephen N.
