Which algorithm is better for encrypt and decrypt Xml document?

Hi,

i am developing one application, i this i am using XML as back-end for storing the data.

In this i need to encrypt this file and whenever i open the application i need to decrypt that fxml file, and i need to use that data in my application.

Which algorithm is better in this criteria ?

Hi,

You have got multiple ways to encrypt/decrypt Xml elements. You can use either Symmetric keys, Assymetric keys orCertificates.

Its been observed DES and TripleDESare quietslow in performance. I usuallyprefer AES(Rjindael).

One option is to use use symmetric-keys to protect your XML elements and then use anasymmetric key to protect thetransfer of yoursymmetric key.

Here's some examples using Rjindael:

Hi,

I've written up something on Xml encryption here..
