Crypt::OpenSSL::SMIME is a brain dead minimalistic not yet secure for use by 
paranoid people wrapper around OpenSSL library which was extremely useful

mailboxes and requires NO additional support from the mail reader software
to decrypt messages unlike PGP.

version 0.04 should compile with OpenSSL 1.x
