The kryptos.info network is comprised of three web sites, a public blog, and a private research group exploring the art and science of information hiding.  This web site, kryptos.info, presents classical cryptography and information hiding as a general public forum.  In conjunction with this open site is a private group on Facebook dedicated to the interactive exploration of Kryptos, Jim Sanborn's CIA sculpture.  The Facebook group is by invitation only.

Kryptos Revisited

RealmOfTwelve.net is home to the original Kryptos web site designed by the kryptos.info network founder, Gary Phillips.  A more general site in content, it includes ideas about Leonardo da Vinci, the science of standing waves, quotes from prominent figures about the history of Kryptos, and several animated illustrations of the Vigenere Cipher and various transpositions.  Realm of Twelve was originally made popular by The Guardian, Liberation, the Wall Street Journal, and several other international publications.  Realm of Twelve was one of only a few web sites available in early 2000 that explored Kryptos in great detail.  It's primary contribution to the Kryptos community was a replica of the Kryptos Sculpture copperplate available to the public as a free graphic download.

The kryptos.info network blog is hosting news and reader comments that pertain to the widely circulated information available publicly.  Every page in this web site links to articles in the blog so that visitors may subscribe to individual story RSS feeds, comments, or the blog itself.
