I use a little command line utility called
scrypt enc pretty frequently.
Originally written as a demonstration for the excellent scrypt key derivation function, it’s a handy little tool that allows me to quickly encrypt files.
I noticed that there didn’t appear to be an implementation that worked on Windows, so I wrote one myself. It’s written in Java and mostly aimed at developers. It should work on Linux, macOS, Windows (and any OS that can run Java).
Hopefully someone finds it useful.
