Member Function Documentation

StaticAlgorithmName()

static std::string LSH384::StaticAlgorithmName ( )

inlinestatic

The algorithm's name.

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

StaticAlgorithmName is not universally implemented yet.

Definition at line 193 of file lsh.h.

AlgorithmName()

std::string LSH384::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.

Member Data Documentation

DIGESTSIZE

const int LSH384::DIGESTSIZE = 48

static

Digest size, in bytes.

LSH_512 uses LSH_GET_HASHBYTE(algType) for digest size, which is 48

Definition at line 182 of file lsh.h.

BLOCKSIZE

const int LSH384::BLOCKSIZE = LSH512_Base::BLOCKSIZE

static

Block size, in bytes.

LSH_512 uses LSH512_MSG_BLK_BYTE_LEN for block size, which is 256
