Encrypt xml file

makecert -r -pe -n "CN=CERT_SIGN_TEST_CERT" -b 01/01/2010 -e 01/01/2012 -sky exchange -ss my

using this command i generate certificate and exported .pfx file from that and this pfx file is used to encrypt the xml file

in .net using EncryptedXml , X509Certificate2, RSACryptoServiceProvider and XmlDocument classes

i encrypt following xml 

<Test><Name>Foo</Name><CardNo>123</CardNo></Test>

as follows:

<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#aes256-cbc" /><KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#"><EncryptedKey xmlns="http://www.w3.org/2001/04/xmlenc#"><EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5" /><KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#"><X509Data><X509Certificate>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</X509Certificate></X509Data></KeyInfo><CipherData><CipherValue>Vyml+mtbeL5bE6EWKNqHfnE1xEkbJglcxbjH3Y7pj9BtXVImAI/SbBdLHatyjIAei7qUfhcn+qYC7WAh48XR78BgqCdJX7O5lfZjVSVeVaQUwl1Bdirdz7RYuveIjDtEIM80W4tB6rq2nOgYNkisxhhwIl7EiCQtT42bSGCKFic=</CipherValue></CipherData></EncryptedKey></KeyInfo><CipherData><CipherValue>ezVeQlBGZRbHqitB2mmHuMvifGB9IhG1g0CWmL8iz37JIIw7x5cGbb5Ap8iy24ACu8TJpwgAGIUWnUTDSZ//kWLzCa3G5HL+jT/RHn+zypk=</CipherValue></CipherData></EncryptedData>

as far as encryption is done using w3c standard. How can i decrypt this xml file on java. I have used .pfx file to encrypt the file. In .net i can decrypt file using following:

 EncryptedXml encXml = new EncryptedXml(xmlEncDoc);  
encXml.DecryptDocument();

How can i decrypt in java, should i pass pfx file to java end? as there is tag in encrypted xml file.

your suggestion is appriciated.

Do you have control over the sender and recipient of the XML message? It would be best to follow the W3 standard for XML Signatures. Java 6 includes full support for digital signatures and there is a good tutorial available which explains how to do it.
