Introduction

This is a textbook implementation of t-out-of-n Shamir secret sharing, using polynomials in a finite field of prime order.

This library was made for an assignment in class, and is not to be used productively. Its interface only allows sharing integers, and it might well be insecure.

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 gf package implements operations and polynomials over a finite field
• The secretshare package implements t-out-of-n secret sharing using polynomials of degree t-1

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 ./....
