Constructor & Destructor Documentation

◆ LSH256()

LSH256::LSH256 ( )
inline

Construct a LSH-256.

LSH_TYPE_256 is the magic value 0x0000020 defined in lsh.cpp.

Definition at line 126 of file lsh.h.

Member Function Documentation

◆ StaticAlgorithmName()

static std::string LSH256::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 122 of file lsh.h.

◆ AlgorithmName()

std::string LSH256::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 128 of file lsh.h.

Member Data Documentation

◆ DIGESTSIZE

const int LSH256::DIGESTSIZE = 32
static

Digest size, in bytes.

LSH_256 uses LSH_GET_HASHBYTE(algType) for digest size, which is 32

Definition at line 111 of file lsh.h.

◆ BLOCKSIZE

const int LSH256::BLOCKSIZE = LSH256_Base::BLOCKSIZE
static

Block size, in bytes.

LSH_256 uses LSH256_MSG_BLK_BYTE_LEN for block size, which is 128

Definition at line 114 of file lsh.h.
