7 Ha! You need to go a few clicks back, or should I say under? What if the
8 hash algo itself is borked and collisions are becoming accepted? What if the
9 RNG you use on your PC is either backdoored by Intel (if hardware generated),
10 or it has such a low entropy that it is trivial to crack its algorithmic
11 derivatives.

13 I was quite surprised to see that the random pool available on a laptop I was
14 working on at the time, was exceedingly lower than the 4096 max entropy.

16 Try this to see yours: cat /proc/sys/kernel/random/entropy_avail

18 I now run sys-apps/haveged in the background, at least when I am generating
19 ssl/gpg/ssh keys.
