XML Security

I am currently working in a project that attempts to secure XML documents. Following is the tool that could be used to implement this.
Source code/executable is currently not posted, as it is still in the beta stage. Some screen shots and sample input/ output are given below.
Even this page will be modified to provide more details. Currently, this page is just meant to be a placeholder!

Sample Input - sample_input.xml

Sample Output - sample_out.xml
