No.  Libgcrypt provides basic building blocks but has no support for
any specific protocol.

It all depends on the protocol used.  Getting the protocol right is
not easy and thus the best advise I can give is to use an established
protocol like OpenPGP or CMS (pkcs#7)

For your application I would simply use a different file suffix or a
special MIME type and pipe the data through gpg while reading.
