Constructor & Destructor Documentation

◆ LSH224()

LSH224::LSH224 ( )
inline

Construct a LSH-224.

LSH_TYPE_224 is the magic value 0x000001C defined in lsh.cpp.

Definition at line 97 of file lsh.h.

Member Function Documentation

◆ AlgorithmName()

std::string LSH224::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 99 of file lsh.h.

◆ CRYPTOPP_CONSTANT() [1/2]

LSH224::CRYPTOPP_CONSTANT ( BLOCKSIZE  = LSH256_Base::BLOCKSIZE)

Block size, in bytes.

LSH_256 uses LSH256_MSG_BLK_BYTE_LEN for block size, which is 128

◆ CRYPTOPP_CONSTANT() [2/2]

LSH224::CRYPTOPP_CONSTANT ( DIGESTSIZE  = 28)

Digest size, in bytes.

LSH_256 uses LSH_GET_HASHBYTE(algType) for digest size, which is 28

◆ StaticAlgorithmName()

static std::string LSH224::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.
