PHP的AES加密填充只有ZeroPadding（补零 - 因为数据长度不是16的整数倍就需要填充），而Java是没

有这种填充模式，杯具的只能自己写一个了，那Java的填充模式就用NoPadding（不填充内容）

Java端代码：

import javax.crypto.Cipher;

import javax.crypto.spec.IvParameterSpec;

import javax.crypto.spec.SecretKeySpec;

import sun.misc.BASE64Decoder;

public class Encryption

{

    public static void main(String args[]) throws Exception {

        System.out.println(encrypt());

        System.out.println(desEncrypt());

    }

    public static String encrypt() throws Exception {

        try {

            String data = "Test String";

            String key = "1234567812345678";

            String iv = "1234567812345678";

            Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");

            int blockSize = cipher.getBlockSize();

            byte[] dataBytes = data.getBytes();

            int plaintextLength = dataBytes.length;

            if (plaintextLength % blockSize != 0) {

                plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize));

            }

            byte[] plaintext = new byte[plaintextLength];

            System.arraycopy(dataBytes, 0, plaintext, 0, dataBytes.length);

            SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");

            IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

            cipher.init(Cipher.ENCRYPT_MODE, keyspec, ivspec);

            byte[] encrypted = cipher.doFinal(plaintext);

            return new sun.misc.BASE64Encoder().encode(encrypted);

        } catch (Exception e) {

            e.printStackTrace();

            return null;

        }

    }

    public static String desEncrypt() throws Exception {

        try

        {

            String data = "2fbwW9+8vPId2/foafZq6Q==";

            String key = "1234567812345678";

            String iv = "1234567812345678";

            byte[] encrypted1 = new BASE64Decoder().decodeBuffer(data);

            Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");

            SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");

            IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

            cipher.init(Cipher.DECRYPT_MODE, keyspec, ivspec);

            byte[] original = cipher.doFinal(encrypted1);

            String originalString = new String(original);

            return originalString;

        }

        catch (Exception e) {

            e.printStackTrace();

            return null;

        }

    }

}

　　Java的填充模式是NoPadding，用自己的编写的补零填充内容；

php：

<?php

$privateKey = "1234567812345678";

$iv 	= "1234567812345678";

$data 	= "Test String";

//加密

$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);

echo(base64_encode($encrypted));

echo '<br/>';

//解密

$encryptedData = base64_decode("2fbwW9+8vPId2/foafZq6Q==");

$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv);

echo($decrypted);

?>
