Image copyright problem with Image:Crypt(D) 128 (N.120 III-2007).pdf
Thank you for uploading Image:Crypt(D) 128 (N.120 III-2007).pdf. However, it currently is missing information on its copyright status. Wikipedia takes copyright very seriously. It may be deleted soon, unless we can determine the license and the source of the image. If you know this information, then you can add a copyright tag to the image description page.

If you have any questions, please feel free to ask them at the media copyright questions page. Thanks again for your cooperation. Shell babelfish 02:12, 5 December 2007 (UTC)
