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:
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:
protected String decryptRijndael256_(String encryptedBase64Text) {
byte[] encryptedBytes = Base64.getDecoder().decode(encryptedBase64Text.getBytes(StandardCharsets.UTF_8));
byte[] key = encryptionKey.getBytes(StandardCharsets.UTF_8);
RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
KeyParameter keyParam = new KeyParameter(key);
rijndaelEngine.init(false, keyParam);
PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());
byte[] decryptedBytes = new byte[bufferedBlock.getOutputSize(encryptedBytes.length)];
int processed = bufferedBlock.processBytes(encryptedBytes, 0, encryptedBytes.length, decryptedBytes, 0);
processed += bufferedBlock.doFinal(decryptedBytes, processed);
decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
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:
org.bouncycastle.crypto.DataLengthException: last block incomplete in decryption
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
:
protected String decryptRijndael256_(String encryptedBase64Text) {
byte[] encryptedBytes = Base64.getDecoder().decode(encryptedBase64Text.getBytes(StandardCharsets.UTF_8));
byte[] key = encryptionKey.getBytes(StandardCharsets.UTF_8);
RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
KeyParameter keyParam = new KeyParameter(key);
rijndaelEngine.init(false, keyParam);
PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());
byte[] decryptedBytes = new byte[bufferedBlock.getOutputSize(encryptedBytes.length)];
int processed = bufferedBlock.processBytes(encryptedBytes, 0, encryptedBytes.length, decryptedBytes, 0);
processed += bufferedBlock.doFinal(decryptedBytes, processed);
decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
return new String(decryptedBytes, StandardCharsets.UTF_8);
}
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:
org.bouncycastle.crypto.DataLengthException: last block incomplete in decryption
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?

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:
RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
KeyParameter keyParam = new KeyParameter(key);
rijndaelEngine.init(false, keyParam);
PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());
替换为:
byte[] iv = new byte[32]; // 0-IV,类似于PHP代码
PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(new CBCBlockCipher(new RijndaelEngine(256)), new ZeroBytePadding());
CipherParameters keyAndIV = new ParametersWithIV(new KeyParameter(key), iv);
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:
decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
return new String(decryptedBytes, StandardCharsets.UTF_8);
可以简化为:
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:
RijndaelEngine rijndaelEngine = new RijndaelEngine(256);
KeyParameter keyParam = new KeyParameter(key);
rijndaelEngine.init(false, keyParam);
PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(rijndaelEngine, new ZeroBytePadding());
with:
byte[] iv = new byte[32]; // 0-IV, analogous to PHP code
PaddedBufferedBlockCipher bufferedBlock = new PaddedBufferedBlockCipher(new CBCBlockCipher(new RijndaelEngine(256)), new ZeroBytePadding());
CipherParameters keyAndIV = new ParametersWithIV(new KeyParameter(key), iv);
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:
decryptedBytes = Arrays.copyOfRange(decryptedBytes, 0, processed);
return new String(decryptedBytes, StandardCharsets.UTF_8);
can be simplified to:
return new String(decryptedBytes, 0, processed, StandardCharsets.UTF_8);
