Signify is a command-line tool for cryptographically signing and verifying files using public-key cryptography. It uses Ed25519 keys to ensure file integrity and authenticity, protecting against tampering. This macOS port brings OpenBSD's secure signing utility to the Apple ecosystem.
Key Features:
  • Ed25519 public-key cryptography
  • Detached signatures for file verification
  • Simple and secure by design
  • Lightweight command-line interface
Use Cases:
  • Verifying downloaded software packages and binaries
  • Ensuring integrity of configuration files or backups
  • Signing release artifacts for distribution
Alternatives:
  • GnuPG – More feature-rich but significantly more complex
  • minisign – Similar lightweight signing approach, also uses Ed25519
