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. ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** crip - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - crip - 3.9-4: normalized package name match | Debian stable package indexes: crip from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | terminal-based ripper/encoder/tagger tool | http://bach.dynet.com/crip/ - Nix - crip: normalized package name match | nixpkgs package indexes: pkgs/by-name/cr/crip/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - crip - 3.9-3: normalized package name match | Ubuntu 24.04 LTS package indexes: crip from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | terminal-based ripper/encoder/tagger tool | http://bach.dynet.com/crip/ - Scoop - extras/crip: normalized package name match | Scoop official bucket manifest trees: bucket/crip.json from https://api.github.com/repos/ScoopInstaller/Extras/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [graalvm](https://www.automicvault.com/pkg/brew/graalvm/) - Build dependency declared by Homebrew. - [maven](https://www.automicvault.com/pkg/brew/maven/) - Build dependency declared by Homebrew. - [certbot](https://www.automicvault.com/pkg/brew/certbot/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [certgraph](https://www.automicvault.com/pkg/brew/certgraph/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [certigo](https://www.automicvault.com/pkg/brew/certigo/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [certstrap](https://www.automicvault.com/pkg/brew/certstrap/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [minica](https://www.automicvault.com/pkg/brew/minica/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [mkcert](https://www.automicvault.com/pkg/brew/mkcert/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [showcert](https://www.automicvault.com/pkg/brew/showcert/) - Shares av.db curated category or tags: certificates, cli, security, tls. - [acme.sh](https://www.automicvault.com/pkg/brew/acme-sh/) - Shares av.db curated category or tags: certificates, cli, security. ## Combined YAML source View the package source record on GitHub.
