Let’s decrypt

AES encrypt in java and decrypt in java, flex, python, C#.

Encrypt: java

<pre lang="java">public static void encrypt(InputStream is, OutputStream out, String secret) throws Exception {
	SecretKey secretKey = new SecretKeySpec(Hex.decodeHex(secret.toCharArray()), "AES");
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);
        out.write(cipher.getParameters().getParameterSpec(IvParameterSpec.class).getIV());
        CipherOutputStream cipherOutputStream = new CipherOutputStream(out, cipher);
        int bufLength = KEY_LENGTH/8 * 100;
        byte buf[] = new byte[bufLength];
        int bytesRead = 0;
	while((bytesRead = is.read(buf)) != -1 ) {
		cipherOutputStream.write(buf, 0, bytesRead);
	}
	cipherOutputStream.close();
}

Decrypt: java

<pre lang="java">public static void decrypt(InputStream is, OutputStream os, String secret) throws Exception{
	SecretKey secretKey = new SecretKeySpec(Hex.decodeHex(secret.toCharArray()), "AES");
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        int ivLenght = KEY_LENGTH/8; //in bytes
        byte iv[] = new byte[ivLenght];
        is.read(iv, 0, ivLenght);
        cipher.init(Cipher.DECRYPT_MODE, secretKey, new IvParameterSpec(iv));
        CipherOutputStream cipherOutputStream = new CipherOutputStream(os, cipher);

        int bufLength = KEY_LENGTH/8 * 100; //this should be 1600 bytes for a 128 bit key
        byte buf[] = new byte[bufLength];
        int bytesRead = 0;
	while((bytesRead = is.read(buf)) != -1 ) {
		cipherOutputStream.write(buf, 0, bytesRead);
	}
	cipherOutputStream.close();
}

Decrypt: flex

<pre lang="actionScript">
var data:ByteArray = body as ByteArray;
var kdata:ByteArray = Hex.toArray(Hex.fromString(key));
var pad:IPad = new PKCS5();
var mode:ICipher = Crypto.getCipher("simple-aes-cbc", kdata, pad);
var blockSize:int = mode.getBlockSize();
pad.setBlockSize(blockSize);
mode.decrypt(data);

Decrypt: python

<pre lang="python">
from Crypto.Cipher import AES
def decrypt(data, secret):
	key = bytearray.fromhex(secret)
	key = str(key)
	iv = data.read(128/8)
	aes = AES.new(key, AES.MODE_CBC, iv)
	return aes.decrypt(data.read())

Decrypt: C#

<pre lang="csharp">

using System.Collections.Generic;
using System.Linq;

using System.IO;
using System.Security.Cryptography;
