With Simple Shamir's Secret Sharing (s4) I want to provide you an easy to use interface for this beautiful little piece of math.

Please note that s4 is provided as it is and I do not take responsibility for any bugs. s4 is a tiny layer around hashicorp vault shamir and golang's AES encryption.

You can use s4 as normal go library in your go projects by importing it via import "github.com/simonfrey/s4" and en-/decrypt bytes to byte shares and vice versa

I assume you have a go build environment setup in your machine.

In order to build & pack the web assembly file for the frontend please use the following command in the top level directory:

./build.sh

This will build you the required file. You now can copy to build folder to your web server (or use it locally) and it should run s4 as intended.

Please use Github Issues in order to report bugs

💸 If you want to tip me for my work on this project feel free to do so 💸

s4 was broadly discussed on HackerNews, and was mentioned in golang weekly in June 2020.
