DLPInit

Initializes user-supplied memory as the
IppsDLPState
 context for future use.

Syntax

IppStatus ippsDLPInit(int
peBits
, int
reBits
, IppsDLPState*
pCtx
);
Include Files
ippcp.h
Parameters
peBits
Bitsize of the GF(
p
) element (that is, the length of the DL-based cryptosystem in bits)
reBits
Bitsize of the multiplicative subgroup GF(
r
).
pCtx
Pointer to the
IppsDLPState
 context being initialized.
Description
The function initializes the memory pointed by
pCtx
 as the
IppsDLPState
 context.
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
.
ippStsSizeErr
Indicates an error condition if
peBits
≤
reBits
.
