And your point is?
What exactly?
I work on the premise that there will be a total catastrophe involved and that none of the hardware in the office will be available to use as it will have been destroyed.
I've been through 2 major floods and that is exactly what I've run into on multiple systems when I was working for IBM to fix these destroyed systems. This wasn't confined to just one company but every client of IBM in Brisbane who was flood affected. In the CBD all the server rooms are underground and every one of them including all the banks where under several floors of muddy junk that was a health hazard to even be near. Then with the water restrictions that where in place we couldn't even hose out the mess. We had to wait weeks till the sludge had turned into a hard mess and then use a fire hose to move the bulk of it into the nearest lift wells so it could be pumped out from there. Most of the hardware involved was covered in a thick brown/black mess that we where not supposed to touch but had to remove it all and unbolt things from the floor and lift cable grates with out using our hands because we where not covered for any injury or sickness that we contracted as a result of this work. Now where exactly would you like to store the encryption keys and still have them usable?
Lets draw a line under this one and agree to disagree.
