Introduction

This is a textbook implementation of a distributed hashed ElGamal Cryptosystem. It utilizes a t-out-of-n secret sharing based on polynomials over a finite field to distribute the private key, and reconstruct the ciphertext.

This library was made for an assignment in class, and should not be used productively as it has not been reviewed.

Getting started

Take a look at demo.go to see the library in use. If you've got a running Golang setup, you may build & run it as follows:

go build demo.go && ./demo

Project structure

The project structure is as follows:

• The demo.go application shows the library in use
• The elgamal package implements the distributed hashed ElGamal cryptosystem

Unit tests

Unit tests use the standard testing library of Go, and may be run using the go test tool. To run all tests, execute go test ./....
