How can I encrypt/decrypt PHP GET parameters?

I have a regular request, for example:

http://myserver.com/index.php?var1=85842.23&var2=212.235&name=Teddie&valid=1

I would like those $_GET parameters be encrypted to something like (not real, just an example:)):

http://myserver.com/index.php?eParam=ks883d48223v2czozoz227272j2nn2dn2d2du3dh4hn4f4f4f4h3383xh8383s38s3j83sj8s3j92h2s89hs387h2s87hs287h2s87h2ui2c3iuhc287z9m2389f

Of course, I need a built in key on each side, that will be able to decrypt that info. Is there any function that may render that possible ? I am not concerned about the client side, as it will be a running application, not a webpage or anything that would be easily reverse-engineered.

Thanks !

Solution

  • Just use SSL (i.e. HTTPS instead of plain HTTP). Then everything except the DNS look up for the domain and that a connection is made to the ip address that domain resolves to will be encrypted.
