# Security Framework Result Codes

Evaluate result codes common to many Security framework functions.

## Discussion

Discussion Use the SecCopyErrorMessageString(_:_:) function to obtain a human readable string corresponding to these status codes. In addition to the codes listed here, certain Security framework services provide additional status codes that are specific to that service. In particular, see Authorization Services Result Codes, Sessions API Result Codes, Secure Transport Result Codes, Secure Download Result Codes, and Code Signing Services Result Codes.
