public PGPPrivateKey getPGPPrivateKey(PGPPublicKey pub, PrivateKey privKey) throws PGPException

Convert a PrivateKey into a PGPPrivateKey.

Parameters
pub:PGPPublicKey

the corresponding PGPPublicKey to privKey.

privKey:PrivateKey

the private key for the key in pub.

Returns:PGPPrivateKey

a PGPPrivateKey

getPGPPublicKeyback to summary
public PGPPublicKey getPGPPublicKey(int algorithm, PGPAlgorithmParameters algorithmParameters, PublicKey pubKey, Date time) throws PGPException

Create a PGPPublicKey from the passed in JCA one.

Note

the time passed in affects the value of the key's keyID, so you probably only want to do this once for a JCA key, or make sure you keep track of the time you used.

Parameters
algorithm:int

asymmetric algorithm type representing the public key.

algorithmParameters:PGPAlgorithmParameters

additional parameters to be stored against the public key.

pubKey:PublicKey

actual public key to associate.

time:Date

date of creation.

Exceptions
PGPException:
on key creation problem.

Parameters
algorithm:int

asymmetric algorithm type representing the public key.

pubKey:PublicKey

actual public key to associate.

time:Date

date of creation.

Exceptions
PGPException:
