Constructor Detail

KeyAgreementKey

public KeyAgreementKey(SecretBuilder builder)
                throws NoSuchSecretException

Initialises the key with the given secret data.

Parameters:

builder - the builder object.

Throws:

NoSuchSecretException - if the secret could not be constructed from the builder.

Method Detail

getKeyAgreement

public KeyAgreement getKeyAgreement(String algorithm,
                                    AlgorithmParameterSpec parameterSpec)

Obtains a key agreement protocol object initialized with this key.

Parameters:

algorithm - the key agreement algorithm, for instance "ECDH" for Elliptic Curve Diffie-Hellman.

parameterSpec - the algorithm parameters.

Returns:

the initialized key agreement object.

Throws:

IllegalStateException - if this key object doesn't contain private key material.

getKeyAgreement

public KeyAgreement getKeyAgreement(String algorithm)

Obtains a key agreement protocol object initialized with this key.

Parameters:

algorithm - the key agreement algorithm, for instance "ECDH" for Elliptic Curve Diffie-Hellman.

Returns:

the initialized key agreement object.

getKeyAgreement

public KeyAgreement getKeyAgreement()

Obtains a key agreement protocol object for this key.

Returns:

the initialized key agreement object.

asCryptoKey
