Encrypt and Decrypt using 128 for Nodejs or Javascript that actually works

nodejs_java_encrypt_decrypt_128.js

// None of the tutorals could help me, so I adapted a few codes.
// What I really want is make a full duplex way between NodeJS and Java, using encrypt/decrypt with AES 128 bit

// 1 - you must have to generate the key
openssl enc -aes-128-cbc -k secret -P -md sha1

// key examples: 
// DCDD74627CD60252E35DFBA91A4556AA
// 2CB24CFDB3F2520A5809EB4851168162
// 468CA14CA44C82B8264F61D42E0E9FA1

// 2 - NodejS
const crypto = require('crypto');
const INITIALIZATION_VECTOR = '0000000000000000';

class Crypt {
    static decrypt128(data, key) {
        const cipher = crypto.createDecipheriv('aes-128-cbc', Buffer.from(key, 'hex'), Buffer.from(INITIALIZATION_VECTOR));
        return cipher.update(data, 'hex', 'utf8') + cipher.final('utf8');
    }
    static encrypt128(data, key) {
        const cipher = crypto.createCipheriv("aes-128-cbc", Buffer.from(key, "hex"), Buffer.from(INITIALIZATION_VECTOR));
        return cipher.update(data, "utf8", "hex") + cipher.final("hex");
    };
}

const key = "YOURKEY";
const data = 'Iguassu Falls is amazing';
const cipher = Crypt.encrypt128(data, key);
const decipher = Crypt.decrypt128(cipher, key);

console.log(cipher);
console.log(decipher);

// 3 - Java

You are genius.

Can you please answer this. This is very similar to what you have already done.

Hi,
I have one question. In javascript part the encodeKey value is never used.

Yes, you are right. I fixed the code and updated a litle bit .
