Detailed Description

When MachO binaries include a LC_CODE_SIGNATURE load command, the __LINKEDIT data segment will include a section corresponding to the LC_CODE_SIGNATURE load command.

This section serves as a signature for the binary. Included in the CodeSignature section is a header followed by a hash of the binary. If present, the CodeSignature section is the last component of the binary.
