Package io.helidon.common.crypto

Class AsymmetricCipher

java.lang.Object

io.helidon.common.crypto.AsymmetricCipher

All Implemented Interfaces:

CommonCipher

public class AsymmetricCipher
extends Object
implements CommonCipher

This class provides simple and stateless way to encrypt and decrypt messages using selected asymmetric cipher.
It requires to have a PrivateKey provided for decryption purposes and a PublicKey for encryption purposes.
