Re: store passwords securely in the internet

[Andre Pawlowski <sqall () h4des org>]

The container is decrypted with this password. If someone entered a 
wrong masterpassword, the program will decrypt the container with this 
wrong masterpassword, then it checks the header and will see that it was 
a wrong masterpassword and gives you an error.

You see, the masterpassword is not stored on the server.
