隐藏URL中发送的字符串

Question

I want to pass some JSON code in the URL as a get parameter, but I don't want anyone will know what I'm sending and also I don't want to store in the DB the data.

Now I'm using base64 encoding to encrypt the JSON but it isn't safe.

Does anyone have another idea how can I do that?

$json = '{"key":"value"}';
$encoded_json = base64_encode($json);

header("Location: http://domain.com/data={$encoded_json}");

Answer 1

Don't encrypt URL parameters. Instead, use a separate look-up.

Also, base64 isn't encryption, it's an encoding scheme.
