How to roll over/transition your 1024 bit DSA keys which are no longer secure to something better using either Thunderbird with Enigmail or GnuPG (GPG) command line interface
All you need to do is installing dropbear (a tiny SSH server) and BusyBox (a tiny shell, usually already installed) using apt-get. The initrd will be recreated automatically. Then reboot your computer.
arver is a tool to manage encrypted harddisks. Imagine you are a collective with several admin members. Your servers have diffrent LUKS encrypted devices. Either you would need 1 password for every device which everyone needs to know or you use arver! Arver has 1 password for each device and for each member. This password is stored encrypted with the personal gpg-key in the data directory. The admins only need to know the password to the their own gpg secret key.
Our approach is different to the default encryption built into distributions such as Ubuntu and Fedora because we don't leave the /boot partition unencrypted on the hard disk. We move it to a bootable USB key along with a far more secure key to unlock the hard disk.
