◆ InitState()
ANONYMOUS_NAMESPACE_END void SM3::InitState |
( |
HashWordType * |
state | ) |
|
|
static |
Initialize state array.
- Parameters
-
state | the state of the hash |
InitState sets a state array to SM3 initial values
Hashes which derive from IteratedHashWithStaticTransform provide static member functions InitState() and Transform(). External classes, like SEAL and MDC, can initialize state with a user provided key and operate the hash on the data with the user supplied state.

◆ StaticAlgorithmName()
CRYPTOPP_STATIC_CONSTEXPR const char * SM3::StaticAlgorithmName |

The algorithm name.
- Returns
- C-style string "SM3"

◆ Transform()
void SM3::Transform |

const HashWordType * |
data |
|
) |
| |
|
static |
Operate the hash.
- Parameters
-
digest | the state of the hash |
data | the data to be digested |
Transform() operates the hash on data
. When the call is invoked digest
holds initial or current state. Upon return digest
holds the hash or updated state.
