Detailed Description
template<unsigned int T_DigestSize>
class Keccak_Final< T_DigestSize >
Keccak message digest template.
- Template Parameters
-
T_DigestSize the size of the digest, in bytes
- Since
- Crypto++ 6.0
Member Function Documentation
◆ BlockSize()
template<unsigned int T_DigestSize>
|
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.
◆ AlgorithmName()
template<unsigned int T_DigestSize>
|
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.
