horcrux

Split your file into encrypted horcruxes so that you don't need to remember a passcode

How it works

horcrux has two commands, split and bind.

Splitting

If I have a file called diary.txt in my current directory I can call

horcrux split diary.txt

and it will prompt me for how many horcruxes I want. If I want 5 horcruxes, it will encrypt my diary.txt file with 5 different secret keys, and then split the encrypted result into 5 equal parts to be stored in .horcrux files along with the 5 secret keys. This means that you will need all five horcruxes to put the thing back together again and decrypt it. The horcrux files will be created like so:

diary_1_of_5.horcrux
diary_2_of_5.horcrux
...

Now you just need to disperse the horcruxes around the house on various USBs or online locations and hope you can recall where they all are!

Binding

To bind the horcruxes back into the original file just call

horcrux bind

in the directory containing the horcruxes (or pass the directory as an argument).

Installation

via homebrew:

brew install jesseduffield/horcrux/horcrux

via binary release

Who this is for:

• People who need to encrypt a big sensitive file like a diary and don't expect to remember any passwords years from now (but who paradoxically will be capable of remembering where they've hidden each horcrux)
• People named Tom Riddle

I have no idea if this program actually has practical use but it's a fun concept that I wanted to implement. I am aware this isn't quite 1:1 with how horcruxes work in the Harry Potter universe but I think it's close enough.
