Reverse obfuscating plain text string urls in PHP

I'm trying to figure out a way to program a function that will de-obfuscate a plain text url.

Something like this:

<input type="hidden" value="kjgajkwe@#jktGAkjgWjkajskd" name="obsfucatedString" />

Then in the processing of that form I want to De-Obsfucate it:

$url = deObfuscate($_POST['obsfucatedString']);
so $url would become something like:
$url = 'http://domain.com/filename.zip';

Is something like that even possible?

I'm trying to hide the url from plain programmer sight.

I guess I would need to write something that would obsfucate the string as well

so

$obsfucatedStringURL = obsfucate('http://domain.com/filename.zip');
Solution

  • Encrypt the URL with a password stored on the server (a good algorithm to use is AES), then decrypt it when you need to obtain the value. A problem with this is that the encrypted string will not be composed of printable characters. To get around this, use base64_encode() to convert the binary encoded string to printable characters that can be added as a value in the <input> field, then use base64_decode() to get back the original value on the server.
