Member Function Documentation

InitState()

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.

Definition at line 230 of file sm3.cpp.

Transform()

void SM3::Transform ( HashWordType * digest, 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.

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()

static const char * SM3::StaticAlgorithmName ( )

inlinestatic

The algorithm name.

Returns

C-style string "SM3"
