Constructor Detail

DataEncryptionKey

public DataEncryptionKey(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

getCipher

public Cipher getCipher(String algorithm,
                        AlgorithmParameterSpec parameterSpec)

Returns an initialized cipher object for the given algorithm and parameters.

Parameters:

algorithm - the cipher algorithm.

parameterSpec - the parameters to initialise the cipher with.

Returns:

the initialized cipher object.

getCipher

public Cipher getCipher(String algorithm,
                        AlgorithmParameters parameters)

Returns an initialized cipher object for the given algorithm and parameters.

Parameters:

algorithm - the cipher algorithm.

parameters - the parameters to initialise the cipher with.

Returns:

the initialized cipher object.

getCipher

public Cipher getCipher(String algorithm)

Returns an initialized cipher object with default parameters.

Parameters:

algorithm - the cipher algorithm.

Returns:

the initialized cipher object.

getCipher

public Cipher getCipher()

Returns an initialized cipher object for an appropriate default algorithm and parameters. A best-effort attempt will be made to pick a strong cipher algorithm based on the type of key.

Returns:

the initialized cipher object.
