Carries out the RSA-SSA signature verification scheme using SHA-224 hash algorithm.
IppStatus ippsRSASSAVerify_SHA224(const Ipp8u* pHMsg, const Ipp8u* pSign, IppBool* pIsValid, IppsRSAState* pCtx);
pHMsg |
Pointer to the octet message hash that has been signed. |
pSign |
Pointer to the octet signature string to be verified. |
pIsValid |
Pointer to the verification result. |
pCtx |
Pointer to the properly initialized IppsRSAState context. |
This function is declared in the ippcp.h file. The function uses SHA-224 hash function and SHA-224-based MGF implemented in Intel IPP to verify a signature according to the RSASSA-PSS scheme and thus is a specific form of the general RSASSAVerify function.
The function may return any of the values that the general RSASSAVerify function returns.
