Encrypt in nodejs and decrypt in php or vice versa

node_crypto.js

var crypto = require('crypto');
var key = 'MySecretKey12345';
var iv = '1234567890123456';
var cipher = crypto.createCipheriv('aes-128-cbc', key, iv);
var decipher = crypto.createDecipheriv('aes-128-cbc', key, iv);

var text = 'plain text';
var encrypted = cipher.update(text, 'utf8', 'binary');
encrypted += cipher.final('binary');
hexVal = new Buffer(encrypted, 'binary');
newEncrypted = hexVal.toString('hex');
console.log('Encrypted: ', newEncrypted);

var decrypted = decipher.update(newEncrypted, 'hex', 'binary');
decrypted += decipher.final('binary');

console.log('Decrypted: ', decrypted);

@vip3r011use any php library/example for aes-128-cbc method, eg: https://gist.github.com/odan/138dbd41a0c5ef43cbf529b03d814d7c

Is this works fine with public key private key encrypt decrypt

I created an updated Gist for use in Web(browsers), Node.JS, command line and PHP 7
https://gist.github.com/Lawlez/88e04e3541cc0608c953a118b86bfc1a

I'm still working on a solution that allows me to use any implementation (Node / PHP / openssl) for encryption and get the web version to decrypt it successfully. currently, I'm still facing issues when trying to decrypt a string in node or web that was encrypted using openssl CLI.

hope it helps
