Mod_BN
Computes modular reduction for input integer big number with respect to specified modulus.
Syntax
IppStatus ippsMod_BN(IppsBigNumState *pA, IppsBigNumState *pM, IppsBigNumState *pR);
Include Files
ippcp.h
Parameters
pA |
Pointer to the integer big number of IppsBigNumState. |
pM |
Pointer to the modulus integer of IppsBigNumState. |
pR |
Pointer to the modular reduction result. |
Description
The function computes the modular reduction for an input integer big number with respect to the modulus specified by a positive integer big number and returns the modular reduction result in the range of [0, (m-1)].
The following pseudocode represents this function:
pR←pAmod pM.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsOutOfRangeErr |
Indicates an error condition if IppsBigNumState *pR is smaller than the length of IppsBigNumState *m. |
ippStsBadModulusErr |
Indicates an error condition if the modulus IppsBigNumState *pM is not a positive integer. |
ippStsContextMatchErr |
Indicates an error condition if any of the context parameters does not match the operation. |
