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:

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

Navigational templates

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

The main crypto navigation box

{{Crypto navbox}}

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.

{{Crypto navbox | block | stream}}

It produces:

{{Crypto navbox | block}}

It produces:

{{Crypto navbox | stream}}

It produces:

{{Crypto navbox | public-key}}

It produces:

{{Crypto navbox | hash}}

It produces:

{{Crypto navbox | machines}}

It produces:

{{Crypto navbox | classical}}
