Detailed Description

WAKE stream cipher operation.

Template Parameters

B	Endianness of the stream cipher

Definition at line 40 of file wake.h.

Member Function Documentation

template<class B = BigEndian>

bool WAKE_Policy< B >::CipherIsRandomAccess ( ) const

inlineprotectedvirtual

Flag indicating random access.

Definition at line 46 of file wake.h.

template<class B >

void WAKE_Policy< B >::CipherSetKey	(	const NameValuePairs &	params,
		const byte *	key,
		size_t	length
	)

protectedvirtual

Key the cipher.

Parameters

params	set of NameValuePairs use to initialize this object
key	a byte array used to key the cipher
length	the size of the key array

Definition at line 65 of file wake.cpp.

Here is the call graph for this function:

template<class B >

void WAKE_Policy< B >::OperateKeystream	(	KeystreamOperation	operation,
		byte *	output,
		const byte *	input,
		size_t	iterationCount
	)

protectedvirtual

Operates the keystream.

Parameters

operation	the operation with additional flags
output	the output buffer
input	the input buffer
iterationCount	the number of iterations to perform on the input

OperateKeystream() will attempt to operate upon GetOptimalBlockSize() buffer, which will be derived from GetBytesPerIteration().
