You give the password to the system while executing the program losetup.
In this moment the loop-device an the file are connected. The cryptogaphic
system ist set up with the key and the encryption and decryptio can work.
The key ist stored in the loop-device.
you do not have to put the password in again.
So do not leave the file and the loop-device connected, while not working
with it. Everybody with the rights (at least root) can access your secrect
information in den file.

I hope this hels.

Bye
Marten
