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.
