GFpSetElementHash
Assigns a value from the input hash to an element of the finite field.
Syntax
IppStatus ippsGFpSetElementHash(const Ipp8u* pMsg, int msgLen, IppsGFpElement* pElm, IppsGFpState* pGF, IppHashAlgId hashID);
Include Files
ippcp.h
Parameters
pMsg |
Pointer to the input message. |
msgLen |
Length of the input message. |
pElm |
Pointer to the context of the finite field element. |
pGF |
Pointer to the context of the finite field. |
hashID |
ID of the hash algorithm used. For details, see table Supported Hash Algorithms. |
Description
This function computes an element of the finite field from the hash of the input message.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNotSupportedModeErr |
Indicates an error condition if hashID does not correspond to any supported hash ID. |
ippStsNullPtrErr |
Indicates an error condition in one of the following cases:
|
ippStsLengthErr |
Indicates an error condition if msgLen is negative. |
ippStsContextMatchErr |
Indicates an error condition if any of thepGF and pElm context parameters does not match the operation. |
ippStsBadArgErr |
Indicates an error condition if the finite field specified by the context pGF is not a prime finite field. |
ippStsOutOfRangeErr |
Indicates an error condition if the length of the element stored in the context pElm is not equal to the length of an element of the finite field specified by the context pGF. |
