Creating a Safe Directory with PAM, EncFS

“This HowTo is about creating a user-session-safe directory which offers security on- and offline. This is done with PAM, a module named pam_script and Encfs (‘Encrypted Filesystem’). This safe directory is used to store credentials and other sensitive information during a session. When a usersession is ended, in the worst case an encrypted directory remains on the harddrive. In the best case everything is removed. This construction is only meant to store information during a session, not for documents or any other valid information.”
