In one of my ASP.Net websites, I have to provide a link to the user in which all query string parameters should be encrypted.What I am thinking is to use the command "aspnet_regiis" (as used to encrypt web.config data), pass output as a query string inside published url.When the user clicks that link, I first decrypt the string and then fetch the original data for the query string.Am right in doing this? Is there any good technique to encrypt and decrypt query strings?

I do need a working ASP.NET C# code to replace characters in a string.
My following code works fine but in case of input "a" it gives me an output as "678d", but in case of input "c" the output is correct as it is i.e. "8d"... Here it automatically replaces the rest values too. I can see the code is executing in a step by step process... This results me to get an overloaded output.
{
StringBuilder builder = new StringBuilder();
builder.Replace("a", "6b");
builder.Replace("b", "7c");
builder.Replace("c", "8d");
return builder.ToString();
}
Now, I do need to replace "a" as just "6b" and it should not load the rest values.
