PRNGSetH0

Sets the initial state with the given input IV for the SHA-1 algorithm.

Syntax

IppStatus ippsPRNGSetH0(const IppsBigNumState*
pH0
, IppsPRNGState*
pCtx
);
Include Files
ippcp.h
Parameters
pH0
Pointer to the initial hash value being set up.
pCtx
Pointer to the
IppsPRNGState
context.
Description
The function resets the initial hash value with the supplied value up to 160 bit length. The supplied big number should be created prior to the function call using the appropriate Big Number Arithmetic functions (see Example ).
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsContextMatchErr
Indicates an error condition if the context parameter does not match the operation.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
