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.

v1.0.0 is the first stable release of the Go CLI and API, twenty months after the first beta.

Think of it as a nice and modern alternative to GPG for asymmetric file encryption.
