AES-128-CBC Decryption with CryptoJS

Encryption with PHP:

use phpseclib3\Crypt\AES;

$cipher = new AES('cbc');
$cipher->setKey(str_repeat('a', 16));
$cipher->setIV(str_repeat('b', 16));

echo bin2hex($cipher->encrypt('test'));

Decryption with Node.js / CryptoJS:

var CryptoJS = require('crypto-js');

var key = CryptoJS.enc.Utf8.parse('aaaaaaaaaaaaaaaa');
var iv = CryptoJS.enc.Utf8.parse('bbbbbbbbbbbbbbbb');
var ciphertext = CryptoJS.enc.Hex.parse('10f42fd95857ed2775cfbc4b471bc213');
ciphertext = {ciphertext: ciphertext};

var plaintext = CryptoJS.AES.decrypt(ciphertext, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC
});

console.log(plaintext.toString(CryptoJS.enc.Utf8));

RSA Decryption

Encryption with PHP:

use phpseclib3\Crypt\PublicKeyLoader;

$key = PublicKeyLoader::load('-----BEGIN RSA PUBLIC KEY-----
MEgCQQCo9+BpMRYQ/dL3DS2CyJxRF+j6ctbT3/Qp84+KeFhnii7NT7fELilKUSnx
S30WAvQCCo2yU1orfgqr41mM70MBAgMBAAE=
-----END RSA PUBLIC KEY-----');
$key = $key->withPadding(RSA::ENCRYPTION_PKCS1);
echo base64_encode($key->encrypt('test'));

Decryption with Node.js:

var crypto = require('crypto');

var ciphertext = "L812/9Y8TSpwErlLR6Bz4J3uR/T5YaqtTtB5jxtD1qazGPI5t15V9drWi58colGOZFeCnGKpCrtQWKk4HWRocQ==";

ciphertext = Buffer.from(ciphertext, 'base64');

var key = `-----BEGIN RSA PRIVATE KEY-----

var plaintext = crypto.privateDecrypt(

        key: key,
        padding: crypto.constants.RSA_PKCS1_PADDING
    },
    ciphertext
);

console.log(plaintext.toString('ascii'));

PKCS8 keys are supported as well as OAEP padding.

RSA Decryption with NodeRSA

Encryption with PHP:

use phpseclib3\Crypt\PublicKeyLoader;

$key = PublicKeyLoader::load('-----BEGIN RSA PUBLIC KEY-----
MEgCQQCo9+BpMRYQ/dL3DS2CyJxRF+j6ctbT3/Qp84+KeFhnii7NT7fELilKUSnx

-----END RSA PUBLIC KEY-----');
$key = $key->withPadding(RSA::ENCRYPTION_PKCS1);
echo base64_encode($key->encrypt('test'));

Decryption with Node.js / NodeRSA:

var NodeRSA = require('node-rsa');

var key = new NodeRSA(`-----BEGIN RSA PRIVATE KEY-----

var plaintext = key.decrypt(ciphertext, 'base64');
plaintext = Buffer.from(plaintext, 'base64');
console.log(plaintext.toString());

PKCS8 keys are supported as is OAEP padding.
