◆ InitState()
void SHA512::InitState |

HashWordType * |

|
|
static |
Initialize state array.
- Parameters
-
state | the state of the hash |
InitState sets a state array to SHA512 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.
- Note
- On Intel platforms the state array must be 16-byte aligned for SSE2.

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 state. Upon return digest
holds the hash or updated state.
