}

//Encrypt
$encrypt_data = myhash()->encrypt("your data","mysecretkey");
$decrypt_data = myhash()->decrypt($encrypt,"mysecretkey");

//Encrypt (return value with base64)
$encrypt_data = myhash()->encrypt("your data","mysecretkey",true);
$decrypt_data = myhash()->decrypt($encrypt,"mysecretkey",true);

You can skip the above by doing this:
