Detailed Description

template<unsigned int T_DigestSize>
class Keccak_Final< T_DigestSize >

Definition at line 74 of file keccak.h.

Constructor & Destructor Documentation

template<unsigned int T_DigestSize>

Keccak_Final< T_DigestSize >::Keccak_Final ( )

inline

Construct a Keccak-X message digest.

Definition at line 81 of file keccak.h.

Member Function Documentation

template<unsigned int T_DigestSize>

unsigned int Keccak_Final< T_DigestSize >::BlockSize ( ) const

inlinevirtual

Provides the block size of the compression function.

Returns

the block size of the compression function, in bytes

BlockSize() will return 0 if the hash is not block based. For example, SHA3 is a recursive hash (not an iterative hash), and it does not have a block size.

Reimplemented from HashTransformation.
