PR - type of getPrivateKey()

PU - type of getPublicKey().

public interface AsymmetricKeyPair<PR extends PrivateKey,PU extends PublicKey>
extends KeySet

Interface for a key pair consisting of a private key with its corresponding public key for asymmetric encryption. The big advantage of asymmetric encryption is that no secret has to be shared between the parties. The public key can be made public and shared. Anybody knowing your public key can encrypt data for you that only you as the owner of the corresponding private key can decrypt. On the other hand only you as the owner of the private key can sign arbitrary data in a way so that everybody can verify this signature using your public key.
