age

age is a straightforward file encryption tool designed for modern security needs. It combines simplicity with robust protection through small explicit keys, post-quantum support, and zero configuration options.

Key capabilities include:

• Multiple encryption methods: Encrypt with passphrases, public keys, SSH keys, or hardware tokens like YubiKeys
• Flexible recipient support: Share encrypted files with multiple recipients who can each decrypt independently
• Hardware integration: Extend functionality through plugins for YubiKeys, Apple Secure Enclave, and hardware wallets
• Cross-platform availability: Works seamlessly on macOS, Windows, Linux, and BSD systems
• UNIX-style composability: Integrates naturally with pipes and command-line workflows
• Interoperable implementations: Available in Go, Rust, and TypeScript for browser and Node.js environments

The tool features a formal specification at age-encryption.org/v1 and provides both command-line usage and a Go library for developers. Installation is available through major package managers on all supported platforms, with pre-built binaries and source compilation options.
