## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

- 2000s: ldid enters the Cydia/saurik tool ecosystem for Mach-O signature manipulation.
- 2020s: Homebrew, MacPorts, and Nix package ldid for developer workstations.

### Related projects

- Related tools and ecosystems include Apple's codesign utility, Cydia packaging, Theos-style iOS development workflows, and general Mach-O binary tooling.
