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. Andre Pawlowski ------------------------------------------------------------------- Ordnung braucht nur der Dumme, das Genie beherrscht das Chaos. -Albert Einstein On 04/07/2010 10:01 PM, Jhfjjf Hfdsjj wrote:
Wait, if the master password is never stored on the hard disk WHERE is it stored? Gotta be somewhere in order for it to be used to decrypt something. ----- Original Message ---- From: Andre Pawlowski<sqall () h4des org> To: security-basics () securityfocus com Sent: Tue, April 6, 2010 2:40:05 PM Subject: store passwords securely in the internet Hi guys, I've written a program to store your passwords secure in a container on a server. It's written for the Horde framework and is called eleusis ( http://h4des.org/index.php?inhalt=eleusis ). The idea was to have your passwords everytime available when you are online even when you are using an internet cafe or a pc at work. When the user creates a passwordstore, he must give a masterpassword. With this masterpassword every password you want to save will encrypt with blowfish. For every step (reading, writing) you have to enter the masterpassword, because nothing will write unencrypted to the hard disk. The masterpassword is never stored. When the user entered the masterpassword, the program will decrypt the container and check the header. If the header is correctly decrypted, the program will continue its work, if not, it will show you an error message. The whole project is written in php. A weak point of the program is the http protocol. When the user doesn't use https to transfer the data the passwords will send decrypted over the net. I hope there is any use for this program and I'm glad if anyone of you send me any critics or suggestions. Regards
