DLPSetKeyPair

Sets private and/or public keys of the DL-based cryptosystem over GF(p).

Syntax

IppStatus ippsDLPSetKeyPair(const IppsBigNumState* pPrivate, const IppsBigNumState* pPublic, IppsDLPState* pCtx);

Include Files

ippcp.h

Parameters

pPrivate

Pointer to the input private key privKey.

pPublic

Pointer to the output public key pubKey.

pCtx

Pointer to the cryptosystem context.

Description

The function stores the private key priveKey and public key pubKey in the cryptosystem 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.

ippStsContextMatchErr

Indicates an error condition if the context parameter does not match the operation.

ippStsIncompleteContextErr

Indicates an error condition if the cryptosystem context has not been properly set up.

ippStsInvalidPrivateKey

Indicates an error condition if the parameter pointed bypPrivate has memory size smaller than the order n of the elliptic curve base point G.

ippStsRangeErr

Indicates an error condition if the parameter pointed by pPublic has memory size smaller than the prime p of the elliptic curve base point G.
