How can JAVA decrypt data which was base64 encoded and RIJNDAEL_256 encryped by PHP?

问题

我需要从一个 PHP 应用迁移数据到一个 JAVA 应用。

这些数据已经使用以下 PHP 函数进行加密：

  1. function encrypt($text, $encryptionKey) {
  2.   return utf8_encode(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $encryptionKey, $text, MCRYPT_MODE_CBC, "
    function encrypt($text, $encryptionKey) {
  3.   return utf8_encode(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $encryptionKey, $text, MCRYPT_MODE_CBC, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0")));
  4. }
  5. function encrypt($text, $encryptionKey) {
  6.   return utf8_encode(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $encryptionKey, $text, MCRYPT_MODE_CBC, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0")));
  7. }
  8. function encrypt($text, $encryptionKey) {

这些数据存储在 MySql-InnoDB 中，表的 collation 设置为 latin1_swedish_ci，在一个 charset 为 utf8 的 VARCHAR(255) 列中。

在 JAVA 中，数据通过使用 Hibernate 的 JPA 存储库检索，然后传递给基于 Rijndael 256 加密与 Java 和 Bouncy Castle 的以下方法：

  1. protected String decryptRijndael256_(String encryptedBase64Text) {
  2.   byte[] encryptedBytes = Base64.getDecoder().decode(encryptedBase64Text.getBytes(StandardCharsets.UTF_8));
  3.   byte[] key = encryptionKey.getBytes(StandardCharsets.UTF_8);
  5.   RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
  6.   KeyParameter keyParam = new KeyParameter(key);
  7.   rijndaelEngine.init(false, keyParam);
  8.   PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());
  10.   byte[] decryptedBytes = new byte[bufferedBlock.getOutputSize(encryptedBytes.length)];
  11.   int processed = bufferedBlock.processBytes(encryptedBytes, 0, encryptedBytes.length, decryptedBytes, 0);
  12.   processed += bufferedBlock.doFinal(decryptedBytes, processed);
  13.   decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
  15.   return new String(decryptedBytes, StandardCharsets.UTF_8);

尽管在大多数情况下这能正常工作，其中加密文本看起来像这样：

5VTv/x2f41Aj2iES7B9lRUi8Q9gH3MYnSR3xc4X1di4= => account.name@gmail.com

... 但如果文本很长，看起来像这样：

p77KGdWlexQXLGPZzkAqk2OK6oC9r7TDfMfaDhofu0et7RaPcA0hUCq0mBnY4oakjZpIrBeMadwhYonVKwJlGw== => very.long.account.name@gmail.c���ե{.c��@*�c�ꀽ���|���G

因此，大部分数据能够正确解码，但最后一个块似乎有问题。我怀疑问题要么与字符编码有关，要么与 MCRYPT_MODE_CBC 及其 IV (\0\0...) 有关。

我还没有找到在 Java 实现中添加模式和 IV 的方法。

关于 Base64 加密，我尝试了 java.util.Base64、org.apache.commons.codec.binary.Base64 和 org.bouncycastle.util.encoders.Base64 中的几乎所有可能的方法。

结果要么如上所示，要么出现以下错误：

  1. org.bouncycastle.crypto.DataLengthException: last block incomplete in decryption
  2. 	at org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher.doFinal(Unknown Source)

我猜测问题与 PHP 如何进行填充有关。

问题：

PHP 和 JAVA 在处理此解密时有什么不同之处？如何能够正确解码所有值？

It is stored in MySql-InnoDB with collation=latin1_swedish_ci in a table with charset=utf8 in a VARCHAR(255) column.

In JAVA the data is retrieved through a JPA-repository using Hibernate and then presented to this
method based on Rijndael 256 encryption with Java & Bouncy Castle
:

  1. protected String decryptRijndael256_(String encryptedBase64Text) {
  2.   byte[] encryptedBytes = Base64.getDecoder().decode(encryptedBase64Text.getBytes(StandardCharsets.UTF_8));
  3.   byte[] key = encryptionKey.getBytes(StandardCharsets.UTF_8);
  5.   RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
  6.   KeyParameter keyParam = new KeyParameter(key);
  7.   rijndaelEngine.init(false, keyParam);
  8.   PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());
  10.   byte[] decryptedBytes = new byte[bufferedBlock.getOutputSize(encryptedBytes.length)];
  11.   int processed = bufferedBlock.processBytes(encryptedBytes, 0, encryptedBytes.length, decryptedBytes, 0);
  12.   processed += bufferedBlock.doFinal(decryptedBytes, processed);
  13.   decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
  15.   return new String(decryptedBytes, StandardCharsets.UTF_8);
  16. }

While this works in most cases where the encrypted text looks like this:

5VTv/x2f41Aj2iES7B9lRUi8Q9gH3MYnSR3xc4X1di4= => account.name@gmail.com

... it fails if the text is long and looks like this:

p77KGdWlexQXLGPZzkAqk2OK6oC9r7TDfMfaDhofu0et7RaPcA0hUCq0mBnY4oakjZpIrBeMadwhYonVKwJlGw== => very.long.account.name@gmail.c���ե{.c��@*�c�ꀽ���|���G

So it is mostly decoded correctly, but the last block seems to be the problem. I suspect the problem lies either with character encoding or with the MCRYPT_MODE_CBC and its IV (\0\0...).

I have not found any way to add the mode and IV to the java implementation.

As for the Base64 encryption. I tried about any possible method from java.util.Base64, org.apache.commons.codec.binary.Base64 and org.bouncycastle.util.encoders.Base64.

The result is either as above or:

  1. org.bouncycastle.crypto.DataLengthException: last block incomplete in decryption
  2. 	at org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher.doFinal(Unknown Source)

My guess is that the problem has to do with how PHP does the padding.

Question:

What is so different between how PHP and JAVA handle this decryption? How can I decode all values correctly?

答案1

得分: 2

问题是由于在发布的代码中使用了ECB模式而不是CBC模式引起的。要应用CBC模式，请进行以下替换：

  1. RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
  2. KeyParameter keyParam = new KeyParameter(key);
  3. rijndaelEngine.init(false, keyParam);
  4. PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());

替换为：

  1. byte[] iv = new byte[32]; // 0-IV，类似于PHP代码
  2. PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(new CBCBlockCipher(new RijndaelEngine(256)), new ZeroBytePadding());
  3. CipherParameters keyAndIV = new ParametersWithIV(new KeyParameter(key), iv);
  4. bufferedBlock.init(false, keyAndIV);

其中key来自于发布的代码。iv是一个包含IV的byte[]，其大小对应于块大小（32字节）。与PHP代码类似，必须使用0-IV（用于解密使用PHP代码加密的数据）。然而，出于安全原因，密钥/IV对只能使用一次。因此，如果密钥是固定的，最好为每次加密随机生成一个IV。

此外，代码：

  1. decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
  2. return new String(decryptedBytes, StandardCharsets.UTF_8);

可以简化为：

  1. return new String(decryptedBytes, 0, processed, StandardCharsets.UTF_8);
英文:

The problem is caused by using the ECB mode instead of the CBC mode in the posted code. To apply the CBC mode replace:

  1. RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
  2. KeyParameter keyParam = new KeyParameter(key);
  3. rijndaelEngine.init(false, keyParam);
  4. PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());

with:

  1. byte[] iv = new byte[32]; // 0-IV, analogous to PHP code
  2. PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(new CBCBlockCipher(new RijndaelEngine(256)), new ZeroBytePadding());
  3. CipherParameters keyAndIV = new ParametersWithIV(new KeyParameter(key), iv);
  4. bufferedBlock.init(false, keyAndIV);

with key from the posted code. iv is a byte[] containing the IV, whose size corresponds to the blocksize (32 bytes). Analogous to the PHP code, a 0-IV has to be used (to decrypt the data encrypted with the PHP code). Note, however, that for security reasons a key/IV pair may only be used once. Therefore, if the key is fixed, it's best to use an IV, which is randomly generated for each encryption.

Furthermore, the code:

  1. decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
  2. return new String(decryptedBytes, StandardCharsets.UTF_8);

can be simplified to:

  1. return new String(decryptedBytes, 0, processed, StandardCharsets.UTF_8);
