Hmmm. This kind of cracking contest seems a little scary to
me. ``Help crack my PGP passphrase'' seems a little too
likely to become ``Help crack this PGP passphrase.'' After
all, how would you know, when handed a key file and some
vague rules, whether the guy who handed it to you was really
the owner of the passphrase, who had forgotten? Especially
over the net? (This is an especially interesting problem
given where you work--you guys probably have some kind of
procedures for convincing yourselves you're not working for
the bad guys, though I don't know what that would be--it
seems like a much harder problem than merely establishing ID
for a CA.)
