CryptoDox does not own copyright on CryptoDox article texts and illustrations. The text contained in CryptoDox is copyrighted by CryptoDox contributors and licensed to the public under the GNU Free Documentation License (GFDL).

Contributors' rights and obligations

If you contribute material to CryptoDox, you thereby license it to the public under the GFDL (with no invariant sections, front-cover texts, or back-cover texts). In order to contribute, you must be in a position to grant this license, which means that either

  • you hold the copyright to the material, for instance because you produced it yourself, or
  • you acquired the material from a source that allows the licensing under GFDL, for instance because the material is in the public domain or is itself published under GFDL.

In the first case, you retain copyright to your materials. You can later republish and relicense them in any way you like. However, you can never retract the GFDL license for the copies of materials that you place here; these copies will remain under GFDL forever.

In the second case, if you incorporate external GFDL materials, as a requirement of the GFDL, you need to acknowledge the authorship and provide a link back to the network location of the original copy.

Using copyrighted work from others

All works are copyrighted unless either they fall into the public domain or their copyright is explicitly disclaimed. If you use part of a copyrighted work under fair use, or if you obtain special permission to use a copyrighted work from the copyright holder under the terms of our license, you must make a note of that fact (along with names and dates). It is our goal to be able to freely redistribute as much of CryptoDox's material as possible, so original images and sound files licensed under the GFDL or in the public domain are greatly preferred to copyrighted media files used under fair use.

Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the project. If in doubt, write it yourself.

Note that copyright law governs the creative expression of ideas, not the ideas or information themselves. Therefore, it is legal to read an encyclopedia article or other work, reformulate the concepts in your own words, and submit it to CryptoDox. However, it would still be unethical (but not illegal) to do so without citing the original as a reference.

Image Hot-linking

Image hot-linking is prohibited on CryptoDox. If you want to use images/media files available on CryptoDox on your site, please copy the file to your server. Do not hot-link. If you try to hot link, a completely different image from what you expected will be shown. This is done to prevent bandwidth stealing.

If you find a copyright infringement

If you suspect a copyright infringement, you should at the very least bring up the issue on that page's talk page. Others can then examine the situation and take action if needed. The most helpful piece of information you can provide is a URL or other reference to what you believe may be the source of the text.

Some cases will be false alarms. For example, if the contributor was in fact the author of the text that is published elsewhere under different terms, that does not affect their right to post it here under the GFDL. Also, sometimes you will find text elsewhere on the Web that was copied from Wikipedia. In both of these cases, it is a good idea to make a note in the talk page to discourage such false alarms in the future.

If some of the content of a page really is an infringement, then the infringing content should be removed, and a note to that effect should be made on the talk page, along with the original source. If the author's permission is obtained later, the text can be restored.

If all of the content of a page is a suspected copyright infringement, then the page should be listed on CryptoDox:Copyright problems and the content of the page replaced by the standard notice which you can find there. If, after a week, the page still appears to be a copyright infringement, then it may be deleted.

In extreme cases of contributors continuing to post copyrighted material after appropriate warnings, such users may be blocked from editing to protect the project.

Articles from Wikipedia

Several articles on CryptoDox may have been taken directly from Wikipedia and enhanced further based on the goals of the CryptoDox project. This is completely legal as both Wikipedia and CryptoDox use the GFDL license.
