Modules Installation

To install the modules, run:

npm install vascomm-rsa-sha

Generating RSA KeyPair

To perform the following actions, you must have OpenSSL installed on your operating system.

1. Move to the directiories where you want to generate the RSA KeyPair.

2. Generating the Private Key

   openssl genrsa -out privateKey.pem 2048

   Notes: you can change privateKey.pem to the desired output name of generated Private Key.

3. Generating the Public Key

   openssl rsa -pubout -in privateKey.pem -out publicKey.pem

   Notes: privateKey.pem must be the Private Key filename. You can change publicKey.pem to the desired output name of generated Public Key.

Usage

let RSA_SHA = require('RSA-SHA');
let fs = require('fs');

let publicKey = fs.readFileSync('/path/to/public/key');
let privateKey = fs.readFileSync('/path/to/private/key');

let text = "Lorem Ipsum"

// Encrypt RSA
let encypted = RSA_SHA.encryptRSA(text, publicKey);
console.log(encypted)

// Decrypt RSA
console.log(RSA_SHA.decryptRSA(encypted, privateKey));

// Sign SHA
let signed = RSA_SHA.signSHA(text, privateKey);
console.log(signed);

//Verify SHA
console.log(RSA_SHA.verifySHA(text,signed, publicKey)); //true
