How to emulate Javascript crypto AES-256-CBC decipher in Java

I have the following Javascript code in a web page:

 var decrypt = function (text, password){ var decipher = crypto.createDecipher('aes-256-cbc',password); var dec = decipher.update(text,'hex','utf8'); dec += decipher.final('utf8'); return dec; } 

, and I'm trying to reproduce it using Java, using the following:

static MessageDigest MD5 = null; static { try { MD5 = MessageDigest.getInstance("MD5"); } catch (NoSuchAlgorithmException e) { throw new RuntimeException(e); } } public static String decrypt(String cipherText, String password) throws GeneralSecurityException, UnsupportedEncodingException { byte[] passwordBytes = hexStringToByteArray(password); byte[] keyBytes = MD5.digest(passwordBytes); byte[] keyAndPassword = new byte[keyBytes.length + passwordBytes.length]; System.arraycopy(keyBytes, 0, keyAndPassword, 0, keyBytes.length); System.arraycopy(passwordBytes, 0, keyAndPassword, keyBytes.length, passwordBytes.length); byte[] ivBytes = MD5.digest(keyAndPassword); SecretKeySpec key = new SecretKeySpec(keyBytes, "AES"); IvParameterSpec iv = new IvParameterSpec(ivBytes); byte[] encrypted = hexStringToByteArray(cipherText); Cipher aesCBC = Cipher.getInstance("AES/CBC/PKCS5Padding"); aesCBC.init(Cipher.DECRYPT_MODE, key, iv); byte[] decryptedData = aesCBC.doFinal(encrypted); return new String(decryptedData, StandardCharsets.UTF_8); } public static byte[] hexStringToByteArray(String s) { int len = s.length(); byte[] data = new byte[len / 2]; for (int i = 0; i < len; i += 2) { data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4) + Character.digit(s.charAt(i + 1), 16)); } return data; } 

which pieces bits from:

• Encrypt with Node.js Crypto module and decrypt with Java (in Android app)
• CryptoJS AES encryption and Java AES decryption

, but I get "javax.crypto.BadPaddingException: Given final block not properly padded", on parameters which the JS function decodes correctly.

Note that Given final block not properly padded does not answer this question- as it is obvious that this is a padding problem but the solution is to replicate whatever the JS crypto lib does, which is not well documented.
