Xml Import security asp.net

I've got an asp.net  program that will create a data set, and then converted to XML, and download it.  I then want to be able to re-import it, and reload the data set to the database.

If I encrypt it, and put a checksum on it, would it be relatively safe from having a sql injection attack built into it between export and import?

If I didn't encrypt it, how might I check it for sql injection attack, considering that it would have unstructured text phrases as part of its content?

Hi,
Your question is so generic for me, so defiantly my generic answer is yes, encrypting file is an option, but it might be other solutions based on your business scenario.

I have some questions:
Who is using your asp.net? I mean here anonymous user or authenticated user?
What is your business scenario you need to apply this export and import functionality?

SQL injection is normally done via http url manipulation and the non checking/validation of user input

Hi,
Maybe his expression is not the right one "SQL Injuction", but what I understand he is afraid of playing with exported xml file before next import, and this file contains data set structure and data.

codequest, correct me if I am wrong.
