User’s Implementation of a Mask Generation Function
In case you prefer or have to use a different implementation of an MGF you can still use IPPCP. To do this, use the definition of MGF introduced in the IPPCP library and described in this section. The declaration provided below also defines an MGF when it is used as a parameter in some Public Key Cryptography operations.
Syntax
typedef IppStatus(_STDCALL *IppMGF)(const Ipp8u* pSeed, int seedLen, Ipp8u* pMask, int maskLen);
Parameters
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. |
Description
This declaration is included in the ippcp.h file. The function generates an octet string of length maskLen according to the implemented algorithm, providing pseudorandom output.
