Detailed Description

template<class B = BigEndian>
class WAKE_Policy< B >

WAKE stream cipher operation.

Template Parameters

B	Endianness of the stream cipher

Since

Crypto++ 1.0

Definition at line 38 of file wake.h.

Member Function Documentation

CipherIsRandomAccess()

template<class B = BigEndian>

bool WAKE_Policy< B >::CipherIsRandomAccess ( ) const

inlineprotectedvirtual

Flag indicating random access.

Returns

true if the cipher is seekable, false otherwise

See also

SeekToIteration()

Implements AdditiveCipherAbstractPolicy.

Definition at line 44 of file wake.h.

CipherSetKey()

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

Implements AdditiveCipherAbstractPolicy.

Definition at line 64 of file wake.cpp.

OperateKeystream()

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().
