PRNGenRDRAND_BN
Generates a pseudorandom positive Big Number of the specified bit length using the RDRAND instruction.
Syntax
IppStatus ippsPRNGenRDRAND_BN(IppsBigNumState* pRand, int nBits, void* pCtx);
Include Files
ippcp.h
Parameters
pRand |
Pointer to the output pseudorandom Big Number. |
nBits |
The number of generated pseudorandom bits. |
pCtx |
Pointer to the IppsPRNGState context. This pointer is unused and can be NULL. |
Description
The function generates a pseudorandom positive Big Number of the specified nBits length. The generation is based on the RDRAND instruction available on latest Intel® processors INTEL_ARCH.
