I have such problem: in my site for clients will be returned (after he will pay) result page in which he should input personal information. It is page my product and the client should not see its URL-address. What functions i can apply and how to do so that the URL-address will be not visible (or will be encrypted).
I don’t understand. Why would you want to do that?
No, it is not the better way. “Encrypting” a URL will not protected your data because that URL will point to the data regardless.
You can’t encrypt a URL because web browsers don’t have a way to decrypt it to display the page. All you can do is to obfuscate it and that means that the browser can then decode it - which also means that any person can too using a browser. So what you are asking for would only work if you use obfuscation to make the address harder to read while showing them the site on your computer so they can’t memorise the address to access it once they get back to their computer.
