Member Function Documentation
◆ InitState()
|
static |
Initialize state array.
- Parameters
-
state the state of the hash
InitState sets a state array to SHA256 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.
◆ Transform()
|
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.
