Constructor Detail

### KeyPair

    public KeyPair(PublicKey publicKey,
                   PrivateKey privateKey)

  Constructs a key pair from the given public key and private key.

  Note that this constructor only stores references to the public and private key components in the generated key pair. This is safe, because `Key` objects are immutable.

  Parameters:
    `publicKey` - the public key.
    `privateKey` - the private key.

Method Detail

### getPublic

    public PublicKey getPublic()

  Returns a reference to the public key component of this key pair.

  Returns:
    a reference to the public key.

### getPrivate

    public PrivateKey getPrivate()

  Returns a reference to the private key component of this key pair.

  Returns:
    a reference to the private key.
