Method Detail

engineSetMode

protected final void engineSetMode(java.lang.String mode)
                            throws java.security.NoSuchAlgorithmException
Description copied from class: javax.crypto.CipherSpi
Set the mode in which this cipher is to run.

engineSetPadding

protected final void engineSetPadding(java.lang.String padding)
                               throws javax.crypto.NoSuchPaddingException
Description copied from class: javax.crypto.CipherSpi
Set the method with which the input is to be padded.

engineGetBlockSize

protected final int engineGetBlockSize()
Description copied from class: javax.crypto.CipherSpi
Returns the block size of the underlying cipher.

engineGetOutputSize

protected final int engineGetOutputSize(int inputLen)
Description copied from class: javax.crypto.CipherSpi

Returns the size, in bytes, an output buffer must be for a call to CipherSpi.engineUpdate(byte[],int,int,byte[],int)>CipherSpi.engineUpdate(byte[],int,int,byte[],int) 55 or CipherSpi.engineDoFinal(byte[],int,int,byte[],int)>CipherSpi.engineDoFinal(byte[],int,int,byte[],int) 55 to succeed.

The actual output length may be smaller than the value returned by this method, as it considers the padding length as well. The length considered is the argument plus the length of any buffered, unprocessed bytes.

engineGetIV

protected final byte[] engineGetIV()
Description copied from class: javax.crypto.CipherSpi
Returns the initializaiton vector this cipher was initialized with, if any.

engineGetParameters

protected final java.security.AlgorithmParameters engineGetParameters()
Description copied from class: javax.crypto.CipherSpi
Returns the parameters that this cipher is using. This may be the parameters used to initialize this cipher, or it may be parameters that have been initialized with random values.
