## What it is
Minisign is a dead simple command-line tool for signing files and verifying digital signatures using the Ed25519 public-key signature system. It is portable, lightweight, cross-platform, and compatible with OpenBSD's signify signature format.

## Use cases
- sign files with a digital signature
- verify file signatures before distribution
- generate ed25519 key pairs for signing
- sign software release artifacts
- replace gpg for simple file signing
- verify downloaded binaries authenticity

## When to avoid
- you need full PGP/GPG key management and web of trust
- you need certificate-based or X.509 signing
- you need integrated key distribution infrastructure

## Facets
- artifact type: cli-tool
- maturity: stable
- function: cryptography, security, cli
- domain: security, developer-tools
- platform: windows, cross-platform, cli
- tags: ed25519, digital-signatures, file-signing, signify-compatible, libsodium, command-line, linux, macos
