MontForm
Converts input positive integer big number into Montgomery form.
Syntax
IppStatus ippsMontForm(const IppsBigNumState* pA, IppsMontState* pCtx, IppsBigNumState* pR);
Include Files
ippcp.h
Parameters
pA |
Pointer to the input integer big number within the range [0, pCtx- 1]. |
pCtx |
Pointer to the input big number modulus of IppsBigNumState. |
pR |
Pointer to the resulting Montgomery form pR = pA*RmodpCtx. |
Description
The function converts an input positive integer big number into the Montgomery form with respect to the big number modulus and stores the conversion result.
The following pseudocode represents this function:
pR←pA*RmodpCtx.
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. |
ippStsBadArgErr |
Indicates an error condition if pA is a negative integer. |
ippStsScaleRangeErr |
Indicates an error condition if pA is more than pCtx. |
ippStsOutOfRangeErr |
Indicates an error condition if IppsBigNumState *pR is larger than IppsMontState *m. |
ippStsContextMatchErr |
Indicates an error condition if any of the context parameters does not match the operation. |
