Wikipedia:WikiProject Cryptography
This is a WikiProject, an area for focused collaboration among Wikipedians. New participants are welcome; please feel free to participate!

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[edit]
Editor oriented lists[edit]
 Index of cryptography articles – Should list all cryptography related articles so please add any new articles to this list. That makes the nifty tool Recent changes in articles about cryptography work properly.
 Category:Cryptography – Crypto images on Wikimedia Commons. (Note that new images should preferably be uploaded to Commons so they can be used in all language Wikipedias.)
 Category:WikiProject Cryptography – Should contain all pages within the WikiProject Cryptography, including some discussions and summaries from the early days of the project.
 Category:Cryptography articles needing expert attention
 Category:Cryptography stubs
 Recently created articles on cryptography – The robot AlexNewArtBot searches for newly created articles several times a week. If they contain any cryptography related words the bot lists those articles here.
Reader oriented lists[edit]
 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 – Should contain all cryptography articles (most of course in subcategories).
Recognized content[edit]
This is a list of recognized content, updated weekly by JLBot (talk · contribs). There is no need to edit the list yourself. If an article is missing from the list, make sure it is tagged (e.g. {{WikiProject Cryptography}}) or categorized correctly. See WP:RECOG for configuration options.

 David Göthberg  I used to work with and teach crypto in embedded systems. That is, how to use crypto in cars and other machinery. Back in the 90's I was part of a team that designed a "trusted computing system" for the cars of a big car manufacturer. So far I have mostly written hash related articles and made hash related diagrams. I am mostly interested in crypto from a programmer and protocol point of view and I like to make diagrams. I am not a math guy or cryptanalyst.

 Note: It seems we are unable to use this author's photographic material — even under the US Fair use (UK Fair dealing) provisions — as the author derives commercial benefit from their sale and has denied WP a right to use.

 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."

Other cryptography encyclopedias[edit]
 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 684 pages, (Aug 10, 2005), Springer (ISBN 038723473X) [1], [2] has some notable cryptographers contributing (e.g. Eli Biham writing Differential cryptanalysis, Joan Daemen and Vincent Rijmen writing Rijndael). 460 articles with a technical summary / academic focus. 2500 references cited.
 Microsoft® Encyclopedia of Security, 800 pages (May 14, 2003), Microsoft Press International, ISBN 0735618771. (Table of contents)^{[dead link]}. While covering the entire field of security, it has entries on a number of crypto topics.

Article talk page[edit]
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 {{WikiProject Cryptography}}, which expands to the following:

{{cryptostub}}[edit]
Instead of {{stub}}, you might want to use {{cryptostub}}. One advantage is that Category:Cryptography stubs gives a list of all the cryptographyrelated stubs. The message is:

If you add this userbox to your userpage you get automatically included in the Category:WikiProject Cryptography participants. It produces:
This user participates in WikiProject Cryptography.

Cryptography has some navigational elements to make it easier for a reader to find related topics.

[edit]
It produces:
This template is the main crypto navigation box. It can be added to the bottom of any cryptography article. This template also has some magic so it can include one or more of the specialised crypto navigation boxes inside the same frame.
To only use this template alone add this code to the bottom of an article:
{{crypto navbox}}
If you want it to also show for instance the specialised navigation box about stream ciphers then give it the "stream" parameter, like this:
{{crypto navbox  stream}}
You can also add several boxes in it, like this:
{{crypto navbox  block  stream}}
Note that the parameters come sort of in backwards order. In the example above the stream cipher box will be on top, followed by the block cipher box and then with the main crypto "navbox" at the bottom.
Here is an invalid example since "navbox" should not be a parameter but instead is part of the address of this template:
{{crypto stream  navbox}}
The available specialised boxes are:
For more details about these navigation boxes please see the description on the page of the main crypto navigation box itself. Below are examples of usage with the specialised boxes.
