# kSecCodeInfoIdentifier

A key whose value is the signing identifier sealed into the signature.

```
let kSecCodeInfoIdentifier: CFString
```

## Discussion

The value is a <doc://com.apple.documentation/documentation/CoreFoundation/CFString> object. Absent for unsigned code.

This is generic information returned regardless of which [Code Signing Information Flags](/documentation/Security/code-signing-information-flags) you pass to the [`SecCodeCopySigningInformation(_:_:_:)`](/documentation/Security/SecCodeCopySigningInformation(_:_:_:)) function.
