# Code Signing Services Result Codes

Recognize result codes specific to the code signing services API.

## Discussion

Discussion Use the SecCopyErrorMessageString(_:_:) function to obtain a human readable string corresponding to these status codes. The functions of the Code Signing Services API may also return the general codes listed in Security Framework Result Codes. In particular, you might expect to encounter errSecSuccess, errSecUnimplemented, errSecParam, and errSecAllocate.
