;  will automatically search the registry-based certificate stores
;  for matching certificates and private keys required for
;  decryption.  However, on Linux, MAX OS X, and other
;  operating systems, no such thing exists.  Therefore, you'll 
;  need to specify one or more PFX (.p12 / .pfx) files as
;  sources for locating the certs required for decyrption.

;  S/MIME security envelopes are automatically "unwrapped"

;  retrieved from the Email object (methods: GetSignedByCert, GetEncryptedByCert; 
;  properties: SignedBy, EncryptedBy, SignaturesValid, Decrypted, ReceivedSigned,
