Wikipedia:WikiProject Cryptography

The aim of WikiProject Cryptography is to help editors working on cryptography articles by providing a repository of information and resources, and providing a place for discussions that affect more than one article.

Lists and categories

Editor oriented lists:

• List of cryptography topics — Recent changes in articles about cryptography
• Redirects for cryptography pages
• /List of images — list of cryptography images
• /CryptographyBlog — a sort-of "Current events" in cryptography; the idea is to list news items about cryptography for potential incorporation into our articles to keep them as up-to-date as possible.

Reader oriented lists:

• Topics in cryptography — an annotated list of cryptography topics
• Books on cryptography — an annotated list of suggested readings.
• List of cryptographers — an annotated list of cryptographers.
• Category:Cryptography

Some open tasks

WikiReader Cryptography — article of the day edit 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 edit Describe cryptanalysis of digital signatures -- what are the various notions (See all to-do lists for this WikiReader)

Free content

• Infosecpedia (old: GFDL new: Creative commons)
• The GNU Privacy handbook (GFDL)
• PlanetMath article on Cryptography and Number Theory (GFDL)
• Wikibooks Cryptography (GFDL) — (most content from Wikipedia anyway)

Other Internet content

• The Handbook of Applied Cryptography — standard academic cryptography reference, available in PDF form.
• RSA Laboratories' FAQ About today's cryptography
• Savard's glossary
• Ritter's Crypto Glossary and Dictionary of Technical Cryptography
• Helger's cryptography pointers
• The FreeS/WAN project's documentation includes a glossary, bibliography, some web links and a discussion of the politics of cryptography.

• Good descriptions of cryptography machines
  • Note: It seems we are unable to use this author's photographic material — even under the US Fair use provision — as the author derives commercial benefit from their sale. The author was approached in April 2004 regarding incorporating his written material into Wikipedia under the GFDL but he declined.
• The ITsecurity.com Dictionary+ of Information Security
• Everything2's coverage of Cryptology topics; their Crypto project
• Cyclopedia Cryptologia — "an online encyclopedia of cryptographic protocols. There will be coverage of a few related topics such as encryption/decryption algorithms and a few historical references, but for the most part, the intent here is to be a reference on cryptographic protocols."
• Crypto law survey, a survey of existing and proposed laws and regulations on cryptography

Other cryptography encyclopedias

• David E. Newton's Encyclopedia of Cryptology (ISBN 0874367727), 1998, has over 550 articles with an overall slant on the history of cryptography, but plenty of modern topics included as well.

• The Encyclopedia of Cryptography and Security (ISBN 038723473X) [1], [2] is to be published by Kluwer sometime in 2005 and has some notable cryptographers contributing (e.g. Eli Biham writing Differential cryptanalysis, Joan Daemen and Vincent Rijmen writing Rijndael). They seem to be aiming at around 500 articles, most with a technical / academic focus. It would likely be profitable to compare their coverage to Wikipedia's.

• Microsoft® Encyclopedia of Security, 800 pages (May 14, 2003), Microsoft Press International, ISBN 0735618771. (Table of contents). While covering the entire field of security, it has entries on a number of crypto topics.

{{CryptographyProject}}

We might wish to tag the Talk: pages of articles which are directly about cryptography with a notice about this WikiProject. For this purpose, there is {{CryptographyProject}}, which expands to the following:

The WikiProject banner below should be moved to this page's talk page. If this is a demonstration of the template, please set the parameter |category=no to prevent this page being miscategorised.

{{crypto-stub}}

Instead of {{stub}}, you might want to use {{crypto-stub}}. One advantage is that Category:Cryptography stubs gives a list of all the cryptography-related stubs. The message is:
