age is a simple, modern and secure file encryption tool.
It features small explicit keys, no config options, and UNIX-style composability.
$ age-keygen -o key.txt
Public key: age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p
$ tar cvz ~/data | age -r age1ql3z7hjy54pw3hyww5ayyfg7zqgvc7w3j2elw8zmrj2kg5sfn9aqmcac8p > data.tar.gz.age
$ age -d -i key.txt -o data.tar.gz data.tar.gz.age

Usage:
age -r RECIPIENT [-a] [-o OUTPUT] [INPUT]
age --decrypt [-i KEY] [-o OUTPUT] [INPUT]
Options:
-o, --output OUTPUT Write the result to the file at path OUTPUT.
-a, --armor Encrypt to a PEM encoded format.
-p, --passphrase Encrypt with a passphrase.
-r, --recipient RECIPIENT Encrypt to the specified RECIPIENT. Can be repeated.
-d, --decrypt Decrypt the input to the output.
-i, --identity KEY Use the private key file at path KEY. Can be repeated.
INPUT defaults to standard input, and OUTPUT defaults to standard output.
RECIPIENT can be an age public key, as generated by age-keygen, ("age1...")
or an SSH public key ("ssh-ed25519 AAAA...", "ssh-rsa AAAA...").
KEY is a path to a file with age secret keys, one per line
(ignoring "#" prefixed comments and empty lines), or to an SSH key file.
Multiple keys can be provided, and any unused ones will be ignored.
