Question

I have developed one application in PHP which uses encryption and decryption.
I have used mcrypt_encrypt and mcrypt_decrypt functions.

But i want to hide my encryption key somehow. so that other network users could not see it.
How can i do that ?

I try to save my key in an individual file and than make exe of that file. but when i execute it on my php page than it returns blank.

I tried -> exec('key.exe',$key); print_r($key);

can anyone help me that how can i hide my encryption key ?
is there any other way ?

Answer 1

I got it working with exec() command.

We cant use file_get_contents('key.exe') because it cant give the original content.

I got the solution with this code

$str = exec('path\key.exe'); 
echo $str;
