MGF_SHA512

Generates a pseudorandom mask of the specified length using SHA-512 hash function.

Syntax

IppStatus ippsMGF_SHA512(const Ipp8u *pSeed, int seedLen, Ipp8u* pMask, int maskLen);

pSeed	Pointer to the input octet string.
seedLen	Length of the input string.
pMask	Pointer to the output pseodorandom mask.
maskLen	Desired length of the output.

This function is declared in the ippcp.h file. The function generates a pseudorandom mask of the specified length using SHA-512 hash algorithm.

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition if pMask pointer is NULL.
ippStsLengthErr	Indicates an error condition if any of the specified lengths is negative or zero.
