Just a quick note: The 'encrypt' challenge has been solved (rather easily due to a bug in the code), the winner will, of course, receive their prize, and there will be another soon (with the bug fixed!)... The current people who have indicated that they have the solution AND provided both the decoded text and their method of attack (only Jim pointed out the broken "AND"). rand-unix.ARPA!jim (Jim Blaise) brown@nsavax (?) There is also a third person who did not include the methodology they used.... they will receive the prize IF and only IF the remainder is received here within 48 hours... otherwise Jim gets the prize.

I wouldn't bother fixing the bug, the encryption program as noted by Jim is still easily cracked with little effort. For a REAL education, post a challenge to crack the DES standard algorithm with say a few screenfulls of english text and a key of your choice. The people from rand might want to wait a good while before telly you they have cracked it, so you can't really find out how quickly they did the job. Needless to say they won't tell you their favorite methods of attack.
