I'm glad to see some public discussion of the weaknesses of
challenge/response authentication for passwords.
C.R.A.P. should be replaced with protocols that don't expose
passwords to dictionary attack.  For stronger alternatives,
see <http://world.std.com/~dpj/links.html>.

The apparent mis-application of RC4 here too just seems like
icing on the cake for hackers.
