T_DigestSize | the size of the digest, in bytes |
|
inlinevirtual |
Provides the block size of the compression function.
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.
|
inlinevirtual |
Provides the name of this algorithm.
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.
Reimplemented from Algorithm.
