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 by
pPrivate
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
.
