anch::crypto::PCBC< Cipher, Padding >::PCBC	(	const std::array< uint8_t, Cipher::getBlockSize()> &	initVect,
		unsigned int	nbThread = `1`
	)

inline

PCBC constructor

Parameters

initVect	the initialization vector
nbThread	the maximum number of thread to run in parallel (default to 1). If is set to 0, it will be set to the number of CPU if found (1 otherwise).

inlineoverrideprotectedvirtual

Cipher a block.
This method will handle initialization vector management.

Parameters

input	the input block to cipher
nbRead	the size of block which has been read
output	the output block
cipher	the cipher instance

Returns: the number of bytes to write

Implements anch::crypto::BlockCipherModeOfOperation< PCBC< Cipher, Padding >, Cipher >.

inlineoverrideprotectedvirtual

Decipher a block.
This method will handle initialization vector management.

Parameters

input	the input block to decipher
nbRead	the size of block which has been read
lastBlock	is last block to decipher
output	the output block
cipher	the cipher instance

Returns: the number of bytes to write

Implements anch::crypto::BlockCipherModeOfOperation< PCBC< Cipher, Padding >, Cipher >.
