Nice list! One I’d add: one of my all-time favorite cryptography-related quotes is from Bruce Schneier‘s Applied Cryptography, talking about key length:

> These numbers have nothing to do with the technology of the devices; they are the maximums that thermodynamics will allow. And they strongly imply that brute-force attacks against 256-bit keys will be infeasible until computers are built from something other than matter and occupy something other than space.
