How to pass a crypted message to browser with GET?

Question

I utilise RSA for crypting some data and I wish to pass data to my server as a GET link in this way:

myserver.ext/index.php?data=Âhå/2#ÛI§cw¦»L¸ÙvóìßKßàë%`N5 Ï'üQn6ÕYì&7ï,Î}:i!öççk\¶Z:Ò/MTÚFÿ*ßÕ®ØÒ¿¢y:ïM&CçëöѤÛ5Âÿ­QöÎÙ Ð=Páë*¹-fð

If I type 'enter' on this link the borwser adds special characters (to purify link I think) and If I print content of 'data' with

echo $_GET['data'];

but php cuts the content. Is there a way to solve this issue?

Thanks.

Edit: I tried with encoding url but RSA decryption doesn't works. The strange thing is that in my local server (LAMPP) it perfectly works, but not on remote server.

Answer 1

you can use these functions to encrypt/decrypt your data

    function rsa_encrypt($yourPublickey, $message)
    {
        $rsa = new Crypt_RSA();
        $rsa->loadKey($yourPublickey);
        $encrypted = urlencode(base64_encode($rsa->encrypt($message)));

        return $encrypted;
    }

    function rsa_decrypt($yourPrivatekey, $cryptedData)
    {
        $rsa = new Crypt_RSA();
        $rsa->loadKey($yourPrivatekey);
        $decrypted = $rsa->decrypt((base64_decode($cryptedData)));

        return $decrypted;
    }

Answer 2

Use either urlencode or base64_encode, and decode accordingly.

Answer 3

For passing slashes by url without changing it into new action or folder you must convert all the "/" to some specific pattern I used "---" and in your code convert all the "---" to "/" and you get your value in the get arguments.

like:

var temp = replaceAll('/','---',your_link);

function replaceAll(find, replace, str) {
 return str.replace(new RegExp(find, 'g'), replace);
}
