Retrieves the designated code requirement of signed code.
- macOS 10.6+
The code or static code object for which you want the designated requirement. If you provide a code object, the function processes it in the same manner as the
Code Copy Static Code(_: _: _:)
On return, the code's designated requirement. Call the
CFReleasefunction to release this object when you are finished with it.
A result code. See Code Signing Services Result Codes.
The designated requirement is the internal code requirement that the code specifies as the way to identify it. See Code Signing Guide for a discussion of code requirements and designated requirements.
If the code contains an explicit designated requirement, a copy of that is returned. If it doesn't, a designated requirement is constructed from the code’s signing authority and its embedded unique identifier. No designated requirement can be obtained from unsigned code. Code that is modified after being signed, that has been signed improperly, or whose signature has become invalid, may or may not yield a designated requirement. This function does not validate the signature.
