# age > A simple, modern and secure file encryption tool. > See `age-keygen` for how to generate key pairs. > More information: . - Generate an encrypted file that can be decrypted with a passphrase: `age --passphrase --output {{path/to/encrypted_file}} {{path/to/unencrypted_file}}` - Encrypt a file with one or more public keys entered as literals (repeat the `--recipient` flag to specify multiple public keys): `age --recipient {{public_key}} --output {{path/to/encrypted_file}} {{path/to/unencrypted_file}}` - Encrypt a file to one or more recipients with their public keys specified in a file (one per line): `age --recipients-file {{path/to/recipients_file}} --output {{path/to/encrypted_file}} {{path/to/unencrypted_file}}` - Decrypt a file with a passphrase: `age --decrypt --output {{path/to/decrypted_file}} {{path/to/encrypted_file}}` - Decrypt a file with a private key file: `age --decrypt --identity {{path/to/private_key_file}} --output {{path/to/decrypted_file}} {{path/to/encrypted_file}}`
