history
Project history and usage
ldid, the Link Identity Editor, is a small command-line utility from Jay Freeman's Cydia ecosystem for manipulating the signature block in a Mach-O binary.
Project history
ldid emerged from iPhone OS and macOS code-signing work that needed a lightweight way to add, refresh, or inspect Mach-O signature metadata outside Apple's full signing workflow. Upstream remains a compact utility hosted in saurik's source repository rather than a broad signing framework.
Adoption history
ldid became familiar in jailbreak and unsigned iOS development toolchains because it can apply ad-hoc signatures and entitlements. The supplied package metadata records availability through Homebrew, MacPorts, and Nix, extending the tool beyond the Cydia packaging environment.
How it is used
The official Cydia page documents three core operations: use -S to sign a binary from scratch and allocate entitlements, -s to update hashes on an existing binary, and -e to dump entitlements.
Why package nerds care
For package maintainers, ldid is a small tool with outsized importance at the boundary of Mach-O packaging, platform signing policy, and iOS development workflows.
Timeline
- 2000s: ldid enters the Cydia/saurik tool ecosystem for Mach-O signature manipulation.
- 2020s: Homebrew, MacPorts, and Nix package ldid for developer workstations.
