Developer Reference for Intel® Integrated Performance Primitives Cryptography
Generates a true random positive Big Number of the specified bit length using the RDSEED instruction.
IppStatus ippsTRNGenRDSEED_BN(IppsBigNumState* pRand, int nBits, void* pCtx);
ippcp.h
pRand |
Pointer to the output true random Big Number. |
nBits |
The number of generated true random bits. |
pCtx |
Pointer to the IppsPRNGState context. This pointer is unused and can be NULL. |
The function generates a true random positive Big Number of the specified nBits length. The generation is based on the RDSEED instruction available on latest Intel® processors [INTEL_ARCH].
