Simple but strong class for encryption

• In the file config.php set a value for the constant PATH,

• Run the script setUp.php via command line,

• Done!

include 'Crypt.php'; $encrypt=new Crypt(); $my_secrect=$encrypt->encrypt("hello"); echo $my_secrect . "\n"; echo $encrypt->decrypt($my_secrect) . "\n"; 

• send encrypted messages between two servers:

  - generate the key_file.php via setUp.php in server A, - set the constant PATH in config.php in server B *without* running the script setUp.php, - upload to server B the key_file.php generated by server A and put it in the path PATH of server B - done!
