I have an application that that needs an id to be passed as part of the URL. Due to security concerns I need to encrypt the id.

Current Scenario -

Expected solution -

The encrypted id will be decoded and used later.

I tried using the encrypt helper..the problem is that special characters are introduced and + or / is part of the encrypted string. This is throwing up all types of problems.

I have also tried to use htmlentities, urlencode, rawurlencode, htmlspecialcharacters as wrappers after encryption. Nothing seems to work as each of these allow the use of ‘/’.

Can someone guide me on what to do ?
Thanks in advance.

Encrypt uses base64_encode before returning the string, so basically, you need to replace all the offending characters with something that isn’t in the base64 alphabet (and is allowed in a url), and then replace it back before decoding it.

works fine for me!

Zenfros solutions works for me.

Regarding using GET ..In my scenario I cant use GET. It is a hyperlink that does some processing.

Thanks
