Wikipedia:WikiProject Cryptography

This is a WikiProject, a collaboration area and open group of editors dedicated to improving Wikipedia's coverage of a particular topic, or to organizing some internal Wikipedia process.
Please see the Guide to WikiProjectsand the Directory of WikiProjectsfor more information. Shortcut:
WP:CRYPT

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. See also the Cryptography WikiPortal.

/List of images – List of cryptography images.

Category:WikiProject Cryptography – Should contain all pages within the WikiProject Cryptography.

Category:Cryptography articles needing expert attention

Category:Cryptography stubs

Participants

If you're interested in editing cryptography articles, you might like to add yourself to this list, possibly with some information on what you know about / like to work on. New additions at the bottom, please.

You might also consider adding yourself to the Category:WikiProject Cryptography participants. See instructions on that category page for how to do it. However, note that that does not get you onto the list here and that the list here has advantages in that you can add a short description of interests.

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 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). While covering the entire field of security, it has entries on a number of crypto topics.

Templates

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:

This article is part of WikiProject Cryptography, an attempt to build a comprehensive and detailed guide to cryptography on Wikipedia. If you would like to participate, you can choose to edit the article attached to this page, or visit the project page, where you can join the project and see a list of open tasks.

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:

This cryptography-related article is a stub. You can helpWikipedia by expanding it.

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

This user is a participant in WikiProject Cryptography.

Navigational templates

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

The main crypto navigation box

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:

If you want it to also show for instance the specialised navigation box about stream ciphers then give it the "stream" parameter, like this:

You can also add several boxes in it, like this:

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:

The available specialised boxes are:

block, stream, public-key, hash, machines, classical

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.

To inform users about the cryptography portal we had this template that could be placed in the "See also" section of articles. However we now recommend using the {{Crypto navbox}} instead.
