The latest snapshots of 0.9.8 support CMS as does the HEAD. There is
documentation for the "cms" utility in the head too and online.

http://www.openssl.org/docs/apps/cms.html

For 0.9.8 snapshots you hve to enable CMS support at compile time with
"enable-cms".

If you don't need the CMS specific features you can use the smime utility
instead which is included in all OpenSSL diestributions.
