Method Details

engineInit

protected void engineInit(int opmode,
                          Key key,
                          AlgorithmParameters params,
                          SecureRandom random)
            throws InvalidKeyException,
                   InvalidAlgorithmParameterException
Initializes this cipher with an operation mode, key, parameters, and source of randomness. If this cipher requires any other initializing data, for example an initialization vector, then it should generate it from the provided source of randomness.
Overrides:
engineInit in interface gnu.javax.crypto.jce.cipher.CipherAdapter
Parameters:
opmode - The operation mode, one of Cipher.DECRYPT_MODE, Cipher.ENCRYPT_MODE, Cipher.UNWRAP_MODE, or Cipher.WRAP_MODE.
key - The key to initialize this cipher with.
params - The algorithm parameters to initialize with.
random - The source of random bytes to use.
Throws:
InvalidAlgorithmParameterException - If the given parameters are not appropriate for this implementation.
InvalidKeyException - If the given key is not acceptable for this implementation.

engineInit

protected void engineInit(int opmode,
                          Key key,

            throws InvalidKeyException
Initializes this cipher with an operation mode, key, and source of randomness. If this cipher requires any other initializing data, for example an initialization vector, then it should generate it from the provided source of randomness.
Overrides:
engineInit in interface gnu.javax.crypto.jce.cipher.CipherAdapter
Parameters:
opmode - The operation mode, one of Cipher.DECRYPT_MODE, Cipher.ENCRYPT_MODE, Cipher.UNWRAP_MODE, or Cipher.WRAP_MODE.
key - The key to initialize this cipher with.
random - The source of random bytes to use.
Throws:
