^The trouble with cryptography is they delete the variables they
   start with.
   If they'd just send along the keys with the encrypted form,
   there'd be no problem.

   It's like my annoyance with calculators; unless it's a printing
   calculator, it deletes what you did before. Makes it hard to
   remember how you got there.

   It's why I like programming better than mathematics; You look at
   the code and, well, there's your variables. Math likes to
   simplify way too much - as if Paper is expensive in 2014. Meh.^
