## Project history and usage

crip is the command-line executable for Certificate Ripper, a small security utility for extracting server certificate chains and exporting them in formats useful to TLS and Java truststore workflows.

### Project history

Certificate Ripper appeared as a Java/GraalVM-oriented CLI project in 2021. The official README positions it as a no-OpenSSL certificate extraction tool with native executables in releases and support for HTTPS, WebSocket, mail, FTP, and database TLS endpoints.

### Adoption history

Official installation instructions cover GitHub releases, Homebrew, the maintainer's Homebrew tap, and Debian/Ubuntu packaging, with additional community packaging for AUR, Nix, Chocolatey, and Scoop. That makes crip notable less for ecosystem size than for broad binary packaging of a narrowly scoped certificate workflow.

### How it is used

Common usage is printing or exporting remote server certificates as human-readable output, PEM, DER, JKS, or PKCS12, including bulk extraction from multiple URLs and proxy-aware operation.

### Why package nerds care

For package indexes, crip is a compact example of a JVM project distributed as native executables as well as a fat JAR, which reduces the usual Java runtime friction for a CLI security tool.

### Timeline

- 2021: Repository created and first public release 0.0.1 published.
- 2021: 1.0.0 release published after early 0.x releases.
- 2022: 2.0.0 release line published.

### Related projects

- GraalVM Native Image is used by the documented native executable build path.
- OpenSSL is an implicit comparison point because the README highlights that crip does not require it.
