Hi,

This looks like a very nice project.

512 bits rather than bytes ?

I just took a look at the screenshots and I'm a bit surprised about the
fact keys are generated from /dev/urandom. Even for 512 bits, that is 64
bytes, wouldn't it be better to read key files from /dev/random ? Unless
there is a setting allowing the user to explicitly choose the source ?

Best,
Quentin
