Member Function Documentation

◆ BlockSize()

template<unsigned int T_DigestSize>
unsigned int SHA3_Final< T_DigestSize >::BlockSize ( ) const
inlinevirtual

Provides the block size of the compression function.

Returns
block size of the compression function, in bytes

BlockSize() will return 0 if the hash is not block based or does not have an equivalent block size. For example, Keccak and SHA-3 do not have a block size, but they do have an equivalent block size called rate expressed as r.

Reimplemented from HashTransformation.

Definition at line 77 of file sha3.h.

◆ AlgorithmName()

template<unsigned int T_DigestSize>
std::string SHA3_Final< T_DigestSize >::AlgorithmName ( ) const
inlinevirtual

Provides the name of this algorithm.

Returns
the standard algorithm name

The standard algorithm name can be a name like AES or AES/GCM. Some algorithms do not have standard names yet. For example, there is no standard algorithm name for Shoup's ECIES.

Note
AlgorithmName is not universally implemented yet.

Reimplemented from Algorithm.
