My problem is: what I encrypt in Java I can decrypt perfectly in Java, but PHP `mcrypt` can't decrypt. What I encrypt with `mcrypt` I can decrypt with `mcrypt`, but can't in Java.

I want to send and receive encrypted data from a Java application to a PHP page, so I need it to be compatible.

Here's what I have...

JAVA...

```
public static String crypt(String input, String key){
    byte[] crypted = null;
    try{
        SecretKeySpec skey = new SecretKeySpec(Base64.decodeBase64(key), "AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, skey);
        crypted = cipher.doFinal(input.getBytes());
    }catch(Exception e){
    }
    return Base64.encodeBase64String(crypted);
}

public static String decrypt(String input, String key){
    byte[] output = null;
    try{
        SecretKeySpec skey = new SecretKeySpec(Base64.decodeBase64(key), "AES");
        Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
        cipher.init(Cipher.DECRYPT_MODE, skey);
        output = cipher.doFinal(Base64.decodeBase64(input));
    }catch(Exception e){
    }
    return new String(output);
}

```

Running:

```
public static void main(String[] args) {
    String key = "Zvzpv8/PXbezPCZpxzQKzL/FeoPw68jIb+NONX/LIi8=";
    String data = "example";
    System.out.println(Cpt.decrypt(Cpt.crypt(data, key), key));
}

```

Output:

```
example

```

PHP...

```
function getEncrypt($sStr, $sKey) {
    return base64_encode(
        mcrypt_encrypt(
            MCRYPT_RIJNDAEL_256, 
            $sKey,
            $sStr,
            MCRYPT_MODE_ECB
        )
    );
}

function getDecrypt($sStr, $sKey) {
    return mcrypt_decrypt(
        MCRYPT_RIJNDAEL_256, 
        $sKey, 
        base64_decode($sStr), 
        MCRYPT_MODE_ECB
    );
}

```

Running:

```
$crypt = getDecrypt(getEncrypt($str, $key), $key);
echo "<p>Crypt: $crypt</p>";

```

Output:

```
Crypt: example�������������������������

```

Using PHP to crypt "example" with key "Zvzpv8/PXbezPCZpxzQKzL/FeoPw68jIb+NONX/LIi8=" I get "YTYhgp4zC+w5IsViTR5PUkHMX4i7JzvA6NJT1FqhoGY=".
Using Java to crypt the same thing with the same key I get "+tdAZqTE7WAVPXhB3Tp5+g==".

I'm encoding and decoding to base64 in the right order and I tested base64 encode and decode compatibility between Java and PHP and it's working.
