Libgcrypt is a libary of cryptgraphic building blocks.  You can't use
it instantly to encrypt files.  You first need to come up with a
protocol on how the encryption should work and then implement this
protocol. The crypto stuff is only a small part.  If you want to look
at such a protocol, see rfc2440.
