Constructor & Destructor Documentation

◆ LSH384()

LSH384::LSH384 ( )

inline

Construct a LSH-384.

LSH_TYPE_384 is the magic value 0x0010030 defined in lsh.cpp.

Definition at line 197 of file lsh.h.

Member Function Documentation

◆ 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.

Definition at line 199 of file lsh.h.

◆ CRYPTOPP_CONSTANT() [1/2]

LSH384::CRYPTOPP_CONSTANT ( BLOCKSIZE = LSH512_Base::BLOCKSIZE )

Block size, in bytes.

LSH_512 uses LSH512_MSG_BLK_BYTE_LEN for block size, which is 256

◆ CRYPTOPP_CONSTANT() [2/2]

LSH384::CRYPTOPP_CONSTANT ( DIGESTSIZE = 48 )

Digest size, in bytes.

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

◆ 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.
