ecryptfs

Hello alltogether

Today I set up an ecryptfs directory, which is automatically mounted at login via pam. To do so i followed the guide in the ecryptfs readme

ecryptfs-readme

To sum up, I now have a key stored in the usser session keyring. The first thing I do not understand is why this key is only showing up via keyctl show and not with the gnome-gui "Passwords and encryption keys".

The second thing I am curious about is the security. I assume that my passphrase is somehow stored on the harddisk. But how exactly and how secure is this?

Thanks in advance
