Package Exports

fdoering-mcrypt

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fdoering-mcrypt) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

NodeJS Encrypt Example

// Require
var mcrypt = require("fdoering-mcrypt");

// Pseudo key **DO NOT USE THIS**
var key = "12345678901234567890123456789012";
// Pseudo initialization vector (iv)
var iv = "abcdefghijklmnopqrstuv1234567890";

// Plaintext
var message = "Hello there!";

// Encrypt
var encrypted_binary = mcrypt.Encrypt(message, iv, key, "rijndael-256", "cbc");

// Convert to Base64 for transporting using Node.js native Buffer class.
var encrypted_base64 = Buffer.from(encrypted_binary, "binary").toString("base64");

NodeJS Decrypt Example

// Convert Base64 back to Binary
var encrypted_binary = Buffer.from(encrypted_base64, "base64").toString("binary");

// Decrypt
var plaintext = mcrypt.Decrypt(encrypted_binary, iv, key, "rijndael-256", "cbc");

// Remove padding
plaintext = plaintext.replace(/\0/g,'');

// Prints "Hello there!"
