Query string hashing

I have set default values for form fields by passing query string variables from code behind. How can I achieve query string hashing to protect data. I have a link like this:

literalControl="<a href='http://test.com/testpage?param1=" + variabl1.Text + "&param2=" + variable2.Text'>click here";

and on bizform i am using {?param1?}

biz form

Hi Jack,
if you want to hash query string, you can use QueryHelper.GetHash() or ValidationHelper.GetHashString() method. These methods return the hash value of the given input. On the page where you need to get any query string parameter value, simply validate the hash using QueryHelper.ValidateHash() or ValdiationHelper.ValidateHash() method. For more details about the hash validation please follow Query string hashing chapter in our documentation.
