There have been a few people who have tried to crack it but I have no idea if the full thing has been solved yet. Tengri137 is fascinating to me. They have used exotic maths (or something) to create many perfect number cubes as part of their puzzles (there were less than a dozen previously known). They also release information that they believe will advance human society. Lots of stuff about them around the web, very interesting. Cicada 3301 is a great steganographic oddity, and for good reason. Here are the links to their twitter, subreddit(s), and an interesting theory about them. The Polish Plague Doctor stego disc that circulated around some tech circles. This is a particularly interesting excersize in steganography because of how many pieces of data are hidden in a single file, the pieces of which are still being figured out. Not to mention, it is strongly themed around the black plauge; spooky. The Voynich Manuscript was a linguistic oddity. Just recently there was a breakthrough that showed the text was written in ancient Turkic. It is still one of the most famous cases of obscured texts. Here is a link to the full text, as well as a transcription of the symbols used. The Copiale Cipher was a manuscript from the 1700's for an ocult order and was completely enciphered. It's a good example of an obfuscated historical text; a full transcription of which can be found here. The Library of Babel can be used to send messages, as technically everything is already written in it. There is also a similar function for images called Babelia in which all images in the 640x416 dimension range theoretically already exist. Stego tools using similar functions are incredibly underutilized. :: Miscellaneous Resources :: OpenPuff (4.00) is a robust steganography tool for media-file manipulation. Online image metadata viewer and ExifTool download plus GUI. CyberChef is an online cipher suite (sourcecode). Cryptii and text tools work too. Sonic Visualizer and Spec are audio spectrometers; full-featured DAWs work too. FLMask is an alternative for the now-defunct G-Mask image manipulation software. Unicode steganography is possible by utilizing the blank/null characters in UTF-8. f5stego.js is a browser plugin for jpeg stego on the fly. SilentEye is a steg tool for injecting messages into pictures and audio files. DeepSound lets you inject any data into audio files. CrypTool is the industry standard for learning and using cryptographic techniques. The OEIS and Nonograms are good for steganography using maths, including audio. PubChem and avogadr.io can be used for chemical steganography. What databending is and how to do it; photomosh for image/video manipulation. The IPA and alternative phonetic arrangements are useful for obfuscating text. Xenotation is a simple but interesting cipher. Learning how to crack basic to advanced ciphers is an important and useful skill; MysteryTwisterC3 hosts many of these kinds of challenges including still-unsolved historical challanges, some of which have significant prize money attached to them. There are similarly-styled puzzles hosted on /r/bitcoinpuzzles which all have prize money associated with them as well. 01010110 01101001 01110110 01100001 00100000 01000011 01100001 01101100 01101001 01100111 01110101 01101100 01100001 00100001
