Make vb.net function secure on web...

[lidds]

I have a VB.Net exe application that has a function in it that contains my encryption method that is used through out my application. This function is used to generate all my encrypted passwords and files etc. therefore for obvious reasons I do not want this to be visible to end users. In my application this is fine as it is compiled as a .exe. However I want to now create a ASP.Net web based version of my application.

Now here comes the question, if I was to create a web version of my application then this function would be visible to the end users along with a large number of other functions that if edited could bypass security and license control. I would like to know what is the best way to keep my ASP.Net webbased version secure from tampering, or is ASP.Net not the best for this?

Really looking for some guidance on how others deal with this.

Thanks

Simon

In client/server web development, the clients cannot see your server side code. I would create a class library to reference in both WebForms and WinForms.
