100

Yeah, i didn't number the last three, but hey, this is my 100th proper journal entry!!!!!!!!!!!

Wow.. not bad to say i didn't expect to manage to do this for more than a week! :-)

Anyway...

Fairly mundane stuff going on as of late... not much to tell... haven't done much computery stuff really... was playing with getting me out of using the Administrator account on my w2k box yesterday... which had some interesting effects on office 2000 and PageMaker 6.5... office wouldn't pick up the installation location to create the personalised settings... had to enable some extra bits for windows installer... which is really dumb... you would *think* that in a supposedly multiple identity OS you'd not need to have extra priveledges to use the OS providers own software... *dumb*... and PM6.5 you have to be a PowerUser to access the bit of the registry that deals with it's settings... again dumb, but almost forgiveable as it's a 95/NT app... and Adobe's site had the info right there for me to fix it... two seconds.... still dumb needing poweruser rights to run an app, but <shrug>... it took over an hour to find the info on M$'s site to figure how to solve the office problem.. and you'd be *amazed* how many things have similar problems... Error 1706... there are lots... even within the o2k/w2k combination there are atleast three different problems with the same error message.... and it was NOT easy to find the one i had... cos it only affects non-admin accounts, so normal home-users don't see it and normal corporate users should have had it installed differently anyway... <grrrr>

Enigma isn't happening the last few days... although I *think* I know how to make the mechanical Enigma *vastly* more un-breakable.... the old no-crash bug (can't get the letter out that you put in... which is termed a 'crash' in Blethley Park speak)... If you use 52 contacts on both sides of the rotors, not the 26 that actually are in place, you can then make a reflector that patches the two contacts for the same position, in effect sending the electrical signal back up the same path as it came down.... you can't do it with only 26 contacts cos electricity won't flow in two directions at once, but i *THINK* that it should work. Obviously you have the contacts for each position on each rotor's 'least-significant' side wired to the contacts for the same position on it's 'most-significant' side, or you break the entire principle of reversability, and so you break Enigma...

So the next step after I have the basic Enigma code working and have my re-configurable Enigma built (the idea being that the applet will be able to act as a 3 or 4 rotor machine, and possibly any configuration that we know existed in the German communications system), then I'll write an additional mode for the applet that will test whether my 52-contact rotors work for enciphering and deciphering in the same way that the true-to-life 26-contact rotors do. Obviously if they do, the next challenge is to see if i can cause a 'crash' between the plaintext and the ciphertext... cos if *that* works, then Enigma's biggest hole just got filled...............

<fx: evil grin> Not that I'm even vaguelly impressed at the idea ;-)

If I can get this working, is anyone out there a cryptographer...? I get a little lost in crpyto-theory around Enigma... I really should sit down one day and pay attention to what I'm reading, with a pen and paper and see if I can manage to break something.... maybe then I can try and break my enhanced-enigma...
