Lists and categories

Editor oriented lists

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

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

This is a list of recognized content, updated weekly by JL-Bot (talk · contribs) (typically on Saturdays). 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 and wait for the next update. See WP:RECOG for configuration options.

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:

{{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:

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.
