Well, I just read Jean's essay and am compelled to add 



a couple of  thoughts.











In regards to this statement by Jean:







"I decided to attack that challenge ASAP, wrongly thinking 



it would be peanuts to achieve, since I thought all the people 



listed in Fravia+'s advanced page did find that page and 



already wrote an essay about it.



I have been very surprised to realize that I prove wrong, 



and that these people wrote about the 'easy' riddle, and not 



the 'hard' one. (Well, you did all right guys, it was not so 



'easy' after all)"






Well Jean, please don't assume because you don't see an essay 



by someone that they havenÆt achieved 'there' goal. Actually, 



I had found the advanced page minutes after I downloaded the 



BMPÆs. 



Basically I reversed Fravia+s thought process and 'felt' password 



in 3 attempts. ( It sounds 



like this is what you eventually ended up doing. Well, actually, I'm not 



sure if I felt the password or felt the Moscow Mule's kick'n.)Thought I 



had the advanced page at that time, I did continue on investigating how 



to reverse it. I seems we did quite a bit of the same searching and 



reading. My dictionary approach was a little different than yours . I 



downloaded many pages and essays regarding stego and wrote a quite 



program to rank 1st ,2nd ... characters.











This is from memory because I no longer have the code. ( I will verify 



it. ) I recall the extracted byte starting at location 0x400 is kind of 



a checksum of the password. 1 byte long. The algorithm was (p1xor p2) 



and 0xFF) xor p3) and 0xFF)...



This means you can divide your 26^8 possibilities by 256 yielding  



815730721 valid possibilities. Therefore your 120 days now become 11 1/2 



hours. That's not too bad.







Even after finding the advanced page I did not write an essay. My guess 



was that this was going to be quite a challenge for everyone. I recalled 



reading the following excerpt from Fravia+'s 1998 courses' opening :











"Awaiting your contribution: mine is only an example of a possible 



project, if each one of you will propose a project



that he would like to develop during this year courses, we could then 



choose together the three-four most interesting



ones, and work -together- to their success.



This is our university, let's exploit fully the might of our joint 



forces, my friends: together we will grow and understand."






My thought was ,even if there were 26^8 possibilities or even if there 



were 26^ 20 possibilities, a brute force attack by one PC is futile. 



But, divide that work among 20 or 100 or 1000 PC's - or even engage 



someone with access to a more powerful machine - it now IS possible. 



What if we set our ego's aside, and joined together to solve a problem. 



And if there were enough of +us working together, what are our limits ?







Well , that's part of why I didnÆt write and essay. Perhaps I should 



have been the one to initiate such and undertaking. I don't know. I'm 



not even sure how to go about organizing such a venture. So, if anyone 



reads this, and thinks it makes any kind of sense at all, then maybe we 



can find a way to it pull together ?
