Encrypt from Java and decrypt on Node.js

Java.java

// Encrypt where jo is input, and query is output and ENCRPYTION_KEy is key
byte[] input = jo.toString().getBytes("utf-8");

MessageDigest md = MessageDigest.getInstance("MD5");
byte[] thedigest = md.digest(ENCRYPTION_KEY.getBytes("UTF-8"));
SecretKeySpec skc = new SecretKeySpec(thedigest, "AES");
Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skc);

byte[] cipherText = new byte[cipher.getOutputSize(input.length)];
int ctLength = cipher.update(input, 0, input.length, cipherText, 0);
ctLength += cipher.doFinal(cipherText, ctLength);

String query = Base64.encodeToString(cipherText, Base64.DEFAULT);

Node.js

var decipher = crypto.createDecipher('aes-128-ecb', encryption_key);

chunks = []
chunks.push( decipher.update( new Buffer(fullBuffer, "base64").toString("binary")) );
chunks.push( decipher.final('binary') );
var txt = chunks.join("");
txt = new Buffer(txt, "binary").toString("utf-8");

// where encryption_key = key, fullBuffer is the input and txt is output
