Minisign
Sign files and verify digital signatures with Minisign, a small command-line signing tool.
About Minisign
Minisign is an open source command-line tool for signing files and verifying digital signatures. It uses the Ed25519 public-key signature system and is designed to focus on file signing with a small codebase. The project repository includes source code, documentation, and build instructions.
With Minisign you can generate a key pair with a public key and a password-protected secret key, sign files to create .minisig signature files, add trusted comments to signatures, and verify signatures using a public key file or key string. It can be installed with Homebrew on macOS and Scoop or Chocolatey on Windows, run as a Docker image, or built from source with Zig or CMake. It is also compatible with signify, the OpenBSD signing tool.
Minisign suits developers and others who distribute files and need a command-line method to sign releases and check signatures on macOS and Windows.
