XML AES解密JAVA [英] XML AES decryption JAVA

问题描述

大家好



我使用C＃RijndaelManaged类使用128位AES加密了xml。我硬编码了IV和密钥字节。我加密的XML看起来像这样。

Hi everyone

I have encrypted an xml using 128 bit AES using C# "RijndaelManaged" Class. I hardcoded the IV and key bytes. My encrypted XML looks like this.

<?xml version="1.0" standalone="yes"?>
<Data>
    <EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element" xmlns="http://www.w3.org/2001/04/xmlenc#"><EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc" />
        <CipherData>
            <CipherValue>ZW97bGRnZHljagIZZV0Ifq160IptZMvv</CipherValue>
        </CipherData>
    </EncryptedData>
</Data>

有谁能告诉我解密这个的java代码...

我已经尝试了几个网但是到目前为止我没有成功..请帮忙！



我想我被困在Java代码中：

Can anyone tell me the java code to decrypt this...
I have tried a few from net but I have not been successful so far.. Please help!

I think I am stuck here in Java Code:

NodeList list = doc.getElementsByTagName("EncryptedData");
Element node = (Element)list.item(0);
String val = node.getNodeValue();
//create the decryption context
DOMDecryptContext dctx = new DOMDecryptContext(keys, node);
//unmarshal encrypted data
EncryptedData encdata = (EncryptedData)fac.unmarshalEncryptedType(dctx);

javax.crypto.spec.IvParameterSpec ivspec = new javax.crypto.spec.IvParameterSpec(ivbyte);
javax.crypto.Cipher cipher = javax.crypto.Cipher.getInstance("AES/CBC/NoPadding");
cipher.init(javax.crypto.Cipher.DECRYPT_MODE, keys, ivspec);

byte[] bytes = encdata.getEncoding().getBytes();
byte[] decrypted = cipher.doFinal(node.); //Stuck here... No idea what to pass here
String str = new String(decrypted);
