browserify-rsa

What is browserify-rsa?

The browserify-rsa package is a Node.js module that provides functionality for RSA encryption and decryption, specifically tailored for use with Browserify. It allows users to perform RSA public and private key operations in a way that is compatible with web browsers.

What are browserify-rsa's main functionalities?

RSA padding

This feature allows for RSA padding when encrypting data. The code sample demonstrates how to use the browserify-rsa package to pad a message using a private key before encryption.

const parseKeys = require('parse-asn1');
const browserifyRsa = require('browserify-rsa');

const privateKey = parseKeys(privateKeyAsn1);
const paddedMessage = browserifyRsa(privateKey, bufferToEncrypt);

RSA decryption

This feature is used for RSA decryption. The code sample shows how to use the browserify-rsa package to decrypt a message using a private key.

const parseKeys = require('parse-asn1');
const browserifyRsa = require('browserify-rsa');

const privateKey = parseKeys(privateKeyAsn1);
const decryptedMessage = browserifyRsa(privateKey, bufferToDecrypt);

Other packages similar to browserify-rsa

node-rsa

node-rsa is a Node.js package that provides RSA encryption, decryption, signing, and verification. It offers a wider range of key formats and more comprehensive functionality compared to browserify-rsa.

forge

forge is a JavaScript library that includes a variety of cryptographic operations including RSA encryption and decryption. It is more feature-rich and not limited to Browserify, unlike browserify-rsa which is tailored for Browserify.

ursa

ursa is a Node.js package that provides bindings to OpenSSL for RSA cryptography. It is more performant for server-side operations as it leverages native code, but it is not designed for browser environments like browserify-rsa.
