@jebba Did you try to store N900 personal data in the encrypted file? In other words, did you try to encrypt the partition that N900 stores personal information? My idea is simple. I want my personal info (contacts, alarms, emails, pins, etc) to be unavailable if my device is stolen or lost. Since there is nothing big deal (I just don't want my pictures, PINs and contacts being posted to the Internet or to credit card scammers), i could use a really fast but not so state of the art encryption...
