## 项目历史与用法

cifer is a small C command-line toolkit for classical cryptanalysis: affine, Vigenere, Bacon, rail-fence, columnar transposition, frequency analysis, buffers, dictionaries, and scripting-oriented shell commands.

### 项目历史

The 1.2.0 source tarball identifies cifer as copyright 2008 by Simrun Basuita and Daniel Richman. Its bundled CHANGES file records an initial 1.0.0 release on 2008-11-29, several maintenance releases in late 2008, and 1.2.0 on 2009-03-10.

The project lived on Google Code and is now represented by the Google Code Archive, which makes it a preserved example of pre-GitHub open-source Unix CLI packaging.

### 采用历史

Homebrew packages cifer 1.2.0 from the Google Code Archive storage tarball and bottles it for macOS and Linux. The Homebrew formula metadata carries a Linux linker-order patch and a readline dependency adjustment, showing the package has been kept buildable despite the upstream project being archival.

Homebrew analytics are very small, with single-digit recent monthly install-on-request counts, so cifer is best understood as a niche historical/security utility rather than a broadly adopted modern security tool.

### 使用方式

The cifer manpage describes an interactive shell with script support. Users load ciphertext into buffers, apply filters, run frequency analysis, brute-force or solve supported classical ciphers, and use cifer-dict to build dictionaries for dictionary-assisted attacks.

### 为什么软件包爱好者会关心

For package maintainers, cifer is interesting because it is an archived Google Code-era C program that Homebrew still builds, bottles, patches on Linux, and tests by invoking the binary. It is the kind of small historical CLI that survives in package managers long after its original hosting platform disappeared.
