I believe the citation that Richard was asking for was one
demonstrating that p9sk1 could be broken by a teenager in an afternoon
(which, to be fair to Ori, is likely just a bit of fun hyperbole meant
to provide some flourish to an otherwise dry subject). The citation
you provided is to an explanation of dp9ik, which while useful, only
addresses what (I believe) Richard was referring to in passing, simply
noting the small key size of DES and how the shared secret is
vulnerable to dictionary attacks.

I should note that a couple of years ago I talked to Eric Grosse about
dp9ik and p9sk1. I'm sure he won't mind if I share that his (early)
impression was that dp9ik is a strict improvement over p9sk1, and that
p9sk1 should be phased out in favor of dp9ik. As a small quip, I do
wish the name were different: c'mon guys, not _everything_ needs to be
snarky. ?;-)
