I may have confused my question. I am going to try to be more specific.
How to send in a secure way the following url using in a hyperlink? I don't want to use submition method.
http:\localhost\test\email=$email&passw\$passw
I don't want the user to see the content of $passw. I have tryed the crypt function, but it doesn't change the value of the variable to its original value.
I looked in a php book and it brings another two functions: encrypt and decrypt with the following example:
<?PHP
$message = "this is a plain text message";
$password = "secret";
$data = encrypt($message, 0, $password);
print(decrypt($data, 0 ,$password));
?>
It didn't work, why? Look the message?
Fatal error: Call to unsupported or undefined function encrypt()
