    From the README

    age 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.

    📜 The format specification is at age-encryption.org/v1. age was designed by @benjojo and @FiloSottile.

    🦀 An alternative interoperable Rust implementation is available at github.com/str4d/rage.

    🌍 Typage is a TypeScript implementation. It works in the browser, in Node.js, and in Bun.

    🔑 Hardware PIV tokens such as YubiKeys are supported through the age-plugin-yubikey plugin.

    ✨ For more plugins, implementations, tools, and integrations, check out the awesome age list.

    💬 The author pronounces it [aɡe̞] with a hard g, like GIF, and is always spelled lowercase.

    On Windows, Linux, macOS, and FreeBSD you can use the pre-built binaries.

    If your system has a supported version of Go, you can build from source.

    Help from new packagers is very welcome.
