I got the gist of your enciphered message, but I think I should confess 
(as I've already hinted upthread) that my decipher code didn't do a 
stellar job, cobbled together as it was in a few minutes, so I'm not 
surprised that others, too, have struggled a bit with decryption. I 
suspect I went from Grand Concept to Code Central far too quickly 
without lingering long enough in Thought Parkway.

Congratulations, therefore are certainly due to yourself and others who 
managed to bolt a few missing wheels onto my train.

CHAL2 is very different. I have tested encryption and decryption 
thoroughly, and have even gone to the trouble of doing the bitmap header 
thing to make encrypted bitmaps viewable, and it works both ways (bmp -> 
encrypted viewable bitmap -> decrypted original file).

So the second challenge is fair.

No takers so far, so you're not too late!
