As for the reverse, the 'smime' utility doesn't do that but you can use the S/MIME API, for example SMIME_write_PKCS7(). The latest snapshot version of the smime utility is also a bit more flexible in that it can handle PKCS#7 structures in PEM format and external content rather than only handling S/MIME messages.
