enchive: init at 3.3

[nico202]

Enchive is a tool to encrypt files to yourself for long-term archival. It's a focused, simple alternative to more complex solutions such as GnuPG or encrypted filesystems. Enchive has no external dependencies and is trivial to build for local use. Portability is emphasized over performance.

The readme says it's compatible with:

Linux, BSD, macOS, Windows

But I tested it only under NixOS, platforms might need to be adjusted

Also, I do not know how to pre-compile the emacs mode that comes with it
