age-file-encryption
age File Encryption
age is a minimal, modern encryption tool. It replaces GPG for most file encryption needs with a much simpler design: small explicit keys, no config files, and clean composability with UNIX pipes.
When to Use This Skill
- Encrypting files or directories before storing or sharing them
- Securely sending files to specific recipients by public key
- Encrypting secrets with a passphrase for backup or storage
- Encrypting to existing SSH public keys (ed25519 or RSA)
- Encrypting to multiple recipients at once
- Encrypting to a GitHub user's SSH keys
- Automating encryption/decryption in scripts
Installation
# macOS / Linux (Homebrew)
brew install age
