age—pronounced [aɡe̞], like the Italian “aghe”—is a simple, modern and secure file encryption tool, format, and Go library.
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 --decrypt -i key.txt data.tar.gz.age > data.tar.gz
