If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To retrieve extended error information, use the GetLastError function.
The following table lists the error codes most commonly returned by the GetLastError function. The error codes prefaced by “NTE” are generated by the particular CSP you are using.
ERROR_BUSY
The hash object specified by hHash is currently being used by another process.
ERROR_INVALID_HANDLE
One of the parameters specifies an invalid handle.
ERROR_INVALID_PARAMETER
One of the parameters contains an invalid value. This is most often an illegal pointer.
NTE_BAD_ALGID
The hHash handle specifies an algorithm that this CSP does not support.
NTE_BAD_HASH
The hash object specified by the hHash parameter is invalid.
NTE_BAD_UID
The CSP context that was specified when the hash object was created cannot be found. |
