Fill RAM with random on trigger

Attacker can recover RAM content (passwords/keys) by freezing it with spray, even after power down! I would recommend filling it with random first, or at least misleading valid words into the free space if previous is not possible because of OS.

Hi @mrx23dot thanks for the feature request!

Currently the app can only lock your screen, so we're pretty far from reaching a point to where this would make sense. First we need to finish #16 and #14. Then implement a shutdown trigger on all 3x platforms.

it sounds it's easier if we fill the RAM with misinformation like 1GB of words, see "how to generate english looking words"

In the meantime, I recommend using the BusKill cable in-line with TAILS to attain this Emergency Shutdown w/ RAM Wiping functionality.
