Parameters
- pPrivate
- Pointer to the input private keyprivKey.
- pPublic
- Pointer to the output public keypubKey.
- 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 isNULL.
- 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 bypPrivatehas memory size smaller than the ordernof the elliptic curve base pointG.
- ippStsRangeErr
- Indicates an error condition if the parameter pointed bypPublichas memory size smaller than the primepof the elliptic curve base pointG.
