High level classes for dealing with OpenPGP objects.

Note: These are based on the org.spongycastle.bcpg classes and use a streaming model, so for some objects which have an input stream associated it is necessary to read to the end of the input stream on the object before trying to read another object from the orginal input stream.

A word on key ring files. For the purpose of this package a PGP key ring is a master key and a collection of sub-keys associated with it. These public and secret key rings are handled by the PGPPublicKey ring class and the PGPSecretKeyRing class respectively. In the case where you are trying to read an key file which has multiple key rings in it, use PGPSecretKeyRingCollection for the secret key file and PGPPublicKeyRingCollection for the public key file.
