Diffie-Hellman

Diffie-Hellman is a lightweight package that provides an implementation of diffie-hellman algorithm in Go. for seeing usages check this.

The Diffie-Hellman is a key-exchange protocol that enables two parties communicating over a public channel to establish a mutual secret without transmitting it over the internet. It allows the two parties to use a public key to encrypt and decrypt their conversation or data using symmetric cryptography.

It is widely used in protocols such as Secure Shell (SSH), Internet Protocol Security (IPSec), and Public Key Infrastructure (PKI) to facilitate secure key exchange and enhance data confidentiality over public networks.

Documentation

Install

go get github.com/erfanmomeniii/diffiehellman

Next, include it in your application:

import "github.com/erfanmomeniii/diffiehellman"

Quick Start

The following example demonstrates how to use this package for generating the same transport key:

package main

import (
	"fmt"

	"github.com/erfanmomeniii/diffiehellman"
)

func main() {
	clientA, _ := diffiehellman.New(10141)
	clientB, _ := diffiehellman.New(10141)
	// The parameter should be a prime number.

	fmt.Println(clientA.GetPrivateKey(), clientA.GetPublicKey())
	// 4294 5299
	fmt.Println(clientB.GetPrivateKey(), clientB.GetPublicKey())
	// 2560 3789
	fmt.Println(clientA.GenerateTransportKey(clientB.GetPublicKey()))
	// 6933
	fmt.Println(clientB.GenerateTransportKey(clientA.GetPublicKey()))
	// 6933
}
