Using /dev/urandom for random input.

Wipe mode is insecure (one pass with 0x00)

Happen to me, i opened xfce-terminal and start moving it right and left until the screen freezed permanently (play for less than 3 minutes with anything like browse some stuff and open close terminal…).

Huge progress has been made.

Implemented by dracut module cold-boot-attack-defense (by security-misc).

Will in near future be available for Kicksecure hosts. Should be easy to port to other Linux distributions.

See design documentation, review welcome:

More documentation, call for testers coming in near future.

Future design (additional kexec based RAM wipe) has been elaborated:

I’ll try to assign this task to implement also the future design to a contractor. Hopefully there will be a good news soon.
