history
Project history and usage
ldid, the Link Identity Editor, is a small Mach-O signing and entitlement utility associated with Jay Freeman's Cydia ecosystem. Its official Cydia package page describes it as a program for manipulating the signature block in a Mach-O binary.
Project history
The tool grew out of iPhone OS and macOS code-signing work where developers needed a lightweight way to add, refresh, or inspect Mach-O signature metadata. Homebrew packages saurik's Git repository and installs both ldid and an ldid2 symlink, reflecting its long use as a command-line helper rather than a large standalone application.
Adoption history
ldid became a familiar dependency in jailbreak and unsigned iOS development toolchains because it could apply ad-hoc signatures and entitlements outside Apple's full signing workflow. Package-manager availability in Homebrew, MacPorts, and Nix made it reachable on developer workstations even though the primary upstream surface stayed minimal.
How it is used
Typical use is direct command-line signing or inspection: the Cydia page documents signing from scratch, updating hashes on an existing binary, and dumping entitlements. That narrow scope is the point: it handles the Mach-O signature block without becoming a broader codesigning framework.
Why package nerds care
For package maintainers, ldid is interesting because it sits at the boundary between platform policy and Unix-style tooling. It is a tiny utility with outsized importance in iOS packaging workflows, and formulae often have to care about source availability, OpenSSL/libplist compatibility, and conflicting ldid variants.
Timeline
- 2000s: ldid appears in the Cydia/saurik tool ecosystem for Mach-O signature-block manipulation.
- 2020s: Homebrew packages saurik's ldid Git repository and installs ldid plus an ldid2 symlink.
Related projects
- Related tools and ecosystems include Apple's codesign utility, Mach-O binary tooling, Cydia packaging, Theos-style iOS development workflows, and downstream ldid forks such as ProcursusTeam/ldid.
