protected void engineSetMode(java.lang.String mode)
                      throws java.security.NoSuchAlgorithmException

Specified by:

engineSetMode in class javax.crypto.CipherSpi

Throws:

java.security.NoSuchAlgorithmException

engineSetPadding

protected void engineSetPadding(java.lang.String padding)
                         throws javax.crypto.NoSuchPaddingException

Specified by:

engineSetPadding in class javax.crypto.CipherSpi

javax.crypto.NoSuchPaddingException

engineInit

protected void engineInit(int opMode,
                          java.security.Key key,
                          java.security.SecureRandom random)
                   throws java.security.InvalidKeyException

Initializes the engine with given operating mode, key, and source of randomness. Generates an initial vector randomly using the given source (if the feedback mode is CBC). If key is of "RAW" format, then it is assumed to employ a plain binary encoding. Any other format causes an InvalidKeyException to be thrown.

Specified by:

engineInit in class javax.crypto.CipherSpi

Throws:

java.security.InvalidKeyException

engineInit

protected void engineInit(int opMode,
                          java.security.Key key,

                   throws java.security.InvalidKeyException,
                          java.security.InvalidAlgorithmParameterException

Initializes the engine with given mode, key, and source of randomness. The IV is taken from the parameter spec, which must be an IvParameterSpec. If key is of "RAW" format, then it is assumed to employ a plain binary encoding. Any other format causes an InvalidKeyException to be thrown.
