Horcrust

Horcrust is a command-line-tool which splits a file into encrypted shards for safekeeping. As long as the specified threshold is met, a user can resurrect their original file at any time - no password necessary.

This project is a Rust implementation of the original horcrux

You can specify where the shards can be placed using the optional directory argument
