DLPValidateKeyPair¶
Validates private and public keys of the DL-based cryptosystem over GF(p).
Syntax¶
IppStatus ippsDLPValidateKeyPair(const IppsBigNumState* pPrivate, const IppsBigNumState* pPublic, IppDLResult* pResult, IppsDLPState* pCtx);
Include Files¶
ippcp.h
Parameters¶
pPrivate |
Pointer to the input private key privKey. |
pPublic |
Pointer to the output public key pubKey. |
pResult |
Pointer to the validation result. |
pCtx |
Pointer to the cryptosystem context. |
Description¶
The function validates the private key privKey and the public key pubKey of the DL-based cryptosystem. The result of the validation is stored in the *pResult and may be assigned to one of the enumerators listed below:
ippDLValid |
Validation has passed successfully. |
ippDLInvalidPrivateKey |
(1 < |
ippDLInvalidPublicKey |
(1 < |
ippDLInvalidKeyPair |

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. |
