Actually smime.c is the utility you want for PKCS#7. Alternatively cms.c if
you want CMS (the successor to PKCS#7).

Those though are general purpose utilities which do all sorts of things which
most appications don't care about. There are some demos in demos/smime and
demos/cms which are much simpler.
