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. |
