The Bouncy Castle Java APIs for the OpenPGP Protocol. The APIs are designed primarily to be used in conjunction with the BC FIPS provider. The APIs may also be used with other providers although if being used in a FIPS context it is the responsibility of the user to ensure that any other providers used are FIPS certified and used appropriately.

There is a newer version: 2.0.9

/**
 * General class to handle JCA key pairs and convert them into OpenPGP ones.
 * 
 * A word for the unwary, the KeyID for a OpenPGP public key is calculated from
 * a hash that includes the time of creation, if you pass a different date to the 
 * constructor below with the same public private key pair the KeyID will not be the
 * same as for previous generations of the key, so ideally you only want to do 
 * this once.
