Member Function Documentation

◆ BlockSize()

template<class T_HashWordType , class T_Endianness , unsigned int T_BlockSize, class T_Base = HashTransformation>
unsigned int IteratedHash< T_HashWordType, T_Endianness, T_BlockSize, T_Base >::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.
