Crypto diagrams

Hey, nice work on the crypto diagrams. I was meaning to ask you for a feistel one, and you beat me to it. Tell me, what program are you using to draw them? -- Finlay McWalter 23:09, 20 Jan 2004 (UTC)

Thanks! I was kind of hoping somebody would notice. I used OpenOffice 1.1's drawing program, which worked great. I just uploaded the originals: Media:Crypto_diagrams.tgz. All of it's for my security class: http://students.cs.byu.edu/~cs465ta/ - maybe if I end up teaching for a long time, all this can eventually be expanded into a free textbook.

Great. I just tried it (subtle font-substition problems on windows, but nothing so serious that I'm going to actually bother to fix). Perhaps a link from the description pages to the .tgz is appropriate? -- Finlay McWalter 20:12, 24 Jan 2004 (UTC)

Done. Lunkwill 03:18, 1 Feb 2004 (UTC)

I second that - really nice work! Especially the highlighting of the garbled bits (which is a lot clearer than other expositions I've seen) and the ECB encrypted Tux - the best exposition I've ever seen on the subject. I've listed it on "Wikipedia:Featured pictures" Securiger 08:12, 27 Feb 2004 (UTC)

Thanks! It's one of my favorite demos, too. My advisor saw it at a conference somewhere; I'd love to find the original source and credit him/her. Lunkwill 23:39, 27 Feb 2004 (UTC)

Hello, just a quick note to invite you to Wikipedia:WikiProject Cryptography! — Matt 17:42, 13 May 2004 (UTC)

Crypto diagrams

Hello, thanks for adding the "encrypted" Tux picture. That reminded me to ask if you had PNG or GIF versions of some of your diagrams that are currently in JPEG format? The reason is that looking at Image:Cbc decryption.jpg, you can make out small compression artifacts that make the picture look a little fuzzy. A non-lossy compression format (like PNG or GIF) would fix that. — Matt 05:47, 22 Jul 2004 (UTC)

File:Crypto diagrams.tgz now has .PNGs of most of the diagrams, including the Feistel network. They're not as big as I remember, but I originally went with .jpg since they came out smaller(!). Feel free to switch to the .PNGs if you prefer them. Lunkwill 06:40, 22 Jul 2004 (UTC)

I don't suppose you could email me this? It seems there's a weird bug; only the old version is downloadable! [my address is matt_crypto <at> yahoo.co.uk] Cheers, — Matt 07:09, 22 Jul 2004 (UTC)

OK, bug automagically fixed itself; I've got the file. — Matt 07:10, 22 Jul 2004 (UTC)

Thanks, I've PNG-ised these, and they look quite a lot better (to me, anyway!) — "cbc decryption.png" was missing; I don't suppose that's easily available, for completeness?— Matt 07:28, 22 Jul 2004 (UTC)

Unfortunately, I accidentally overwrote the Openoffice drawing with the modification attack. But now that I look, you're in luck -- I do have a .png of it. I'll add it to the .tgz and Modes page. Lunkwill 16:19, 22 Jul 2004 (UTC)

Thanks! — Matt 22:38, 22 Jul 2004 (UTC)

WikiReader Cryptography

Hello, this is a quick note to let you know about the WikiReader in Cryptography; I don't know if you'd be interested in this project, but the idea is to work towards a printable selection of articles in cryptography. There's now a provisional Table of Contents to work with, and for the next 68 days or so there'll be an "Article of the Day" scheme: each day there'll be a particular article highlighted for reviewing and fixing. There's two templates for this purpose: Template:WikiReaderCryptographyAOTD and Template:WikiReaderCryptographyAOTD-Verbose. The smaller one looks like this:

WikiReader Cryptography — article of the day MRR Sunday, 24 July Playfair cipher (Talk) (History) Monday, 25 July Message authentication code (Talk) (History) Tuesday, 26 July Digital signature (Talk) (History) Wednesday, 27 July Block cipher modes of operation (Talk) (History) Thursday, 28 July Export of cryptography (Talk) (History) Notes: If you find problems that you can't fix (or it's too much effort), it would be very helpful if you could place a note on the Talk: page. Articles need to be checked for 1) Accuracy (Factchecking: Are there any mistakes? Is the writing precise? Are sources cited?), 2) Completeness (Any obvious omissions? Does it need illustration?) 3) Quality of writing (Copyedits: Grammar and spelling, phrasing, structure) 4) Neutrality (Is it written from the NPOV? Do we document all relevant points of view?) — Thanks! — To-do list for Digital signature Describe cryptanalysis of digital signatures -- what are the various notions (See all to-do lists for this WikiReader)

These articles are likely to be some of the earliest English Wikipedia content to get turned into a print version, and any help in making them as good as possible would be much appreciated. Thanks! — Matt 02:11, 29 Jul 2004 (UTC)

Hi, I've replied to Wikipedia_talk:WikiReader/Cryptography#AOTD_needs_updated and reactivated the AOTD box. — Matt 13:59, 16 Nov 2004 (UTC)

antelope photos

The 4 photos you took of antelope and put in the gazelle page were actually of oryx and eland. I have taken them down, but the oryx one is good for that article and I plan to do a piece on eland so I'll use them for that (when I get round to it! I am trying to do too much round here) sunbird 22:37, 18 Nov 2004 (UTC)

Thanks! It's been bugging me a long time that I wasn't sure what they were. I even did a bunch of image searches, but never fully straightened it out. I took a bunch of pictures at the safari; feel free to use any additional ones: http://lunkwill.org/pics/austin/0thumbs.html Lunkwill 22:40, 18 Nov 2004 (UTC)

No problem. The Oryx picture now dominates the East African Oryx arcticle. I don't recognise the species of deer in the taxobox, the antlers are growing in so it's hard to use them. Where did you take it? I'll use the others as time allows, busy busy! sunbird 23:00, 18 Nov 2004 (UTC)

There's a drive-through safari in San Antonio; lots of fun. Lunkwill 23:13, 18 Nov 2004 (UTC)

Hey, we met at Crypto 2003

Hey Jason, this is Derek Williams. I recall we met at Crypto 2003 at the crypto teachers bof session and had planned on doing some sort of online repository of crypto stuff. Sorry that ended up not working out. The guy who was doing most of the work on our end later ended up dropping out of school to work as a software developer somewhere in New England. I've since moved on to the University of Waterloo. I take from your user page that you're still with BYU? How are things? CryptoDerk 05:44, Nov 22, 2004 (UTC)

Yeah, that never really took off. I'm doing great, working on a Ph.D. and doing lots of crypto/credential stuff. How about you? Neat to see this cryptography reader taking off, eh? Lunkwill 22:27, 22 Nov 2004 (UTC)
