How to Build a Maze It's easier than you think. Our objective here is to create a perfect maze, the simplest type of maze for a computer to generate and solve. A perfect maze is defined as a maze which has one and only one path from any point in the maze to any other point. This means that the maze has no inaccessible sections, no circular paths, no open areas.
Cryptologist- Spies All Around Us! Cryptologist Cryptology - (krip tal' e je) n. the study of secret codes or ciphers and the devices used to create and decipher them. - Webster's New World College Dictionary, Fourth Edition. As a cryptologist you will be responsible for devicing a code for your spy letter. The following websites should be helpful to you in determining your code.

This utility is the counterpart to the Steganography encoding utility here . Go encode an image to use here if you haven't already. This utility and its counterpart are based on the cool cryptographic tool created by Lenny Domnitser which lets you hide arbitrary text inside of an image using the black art of steganography Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient even realizes there is a hidden message. Get the most recent version of Lenny's Stepic code here . Steganography_Decode - Utility Mill - Utility
GC1M2NP A Lesson in Ciphers # 1 (Unknown Cache) in Missouri, United States created by TripCyclone This cache series is designed to give you an introduction to the world of ciphers. It will not cover every type of cipher out there, instead focusing on a small variety of different ciphers. Hopefully, you will walk away from solving this series with a new set of puzzle solving skills. And maybe, just maybe, you'll be able to go to that puzzle that's always bothered you and begin to see it with a new pair of eyes. I have designed this series such that you will not be able to solve them all in one swipe.
When looking at the steganographic tools available on the Net, it occurred to me that nothing had been done to hide information in MP3 files, that is sound tracks compressed using the MPEG Audio Layer III format. There is a growing interest world-wide in MP3 or indeed WMA files because they offer near-CD quality at compression ratio of 11 to 1 (128 kilobits per second). This gives a very good opportunity for information hiding . Although WMA has better quality in general, I did not have access to code and only an implementation for MP3 is provided as a proof of concept . MP3Stego will hide information in MP3 files during the compression process. MP3Stego
When I wrote my first book, Fermat’s Last Theorem, I made a passing reference to the mathematics of cryptography. Although I did not know it at the time, this was the start of a major interest in the history and science of codes and code breaking, which has resulted in a 400-page book on the subject, an adaptation of the book for teenagers, a 5-part TV series, numerous talks and lectures, the purchase of an Enigma cipher machine and the development of an interactive crypto CD-ROM. In the Crypto Corner, you will find details about my book on cryptography ( The Code Book ), information about my TV series based on the book ( The Science of Secrecy ) and you can explore the Black Chamber , which is an interactive encryption and codebreaking section. You will also find a section about the Cipher Challenge , there are some cryptograms (coded messages) for you to try and crack, a free downloadable CD-ROM version of The Code Book, and a quick Q&A based on the questions I am most often asked.

One variation to the standard Caesar cipher is when the alphabet is "keyed" by using a word. In the traditional variety, one could write the alphabet on two strips and just match up the strips after sliding the bottom strip to the left or right. To encode, you would find a letter in the top row and substitute it for the letter in the bottom row. For a keyed version, one would not use a standard alphabet, but would first write a word (omitting duplicated letters) and then write the remaining letters of the alphabet. For the example below, I used a key of "rumkin.com" and you will see that the period is removed because it is not a letter. Keyed Caesar

Puzzled residents across Yorkshire are turning detective after mysterious stone heads were left outside their properties in the dead of night. The sculptures feature the same carved symbol and come with a riddle attached. Despite CCTV film showing a man leaving three heads outside a post office, their origin remains unknown. So far, 12 have appeared in Goathland and Kilburn, North Yorkshire; four in Arthington, West Yorkshire and three in Braithwell in South Yorkshire. UK | England | Carvings riddle stumps villagers
Cipher In cryptography , a cipher (or cypher ) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment . To encipher or encode is to convert information from plain text into code or cipher. In non-technical usage, a "cipher" is the same thing as a " code "; however, the concepts are distinct in cryptography.
Let's say that you need to send your friend a message, but you don't want another person to know what it is. You can use a full-blown encryption tool, such as PGP. If the message isn't that important or if it is intended to be decrypted by hand, you should use a simpler tool.
Pict-O-Caches | Trip's GeoAdventures If there was ever a cache that everyone should try once, pict-o-caches would likely be near the top of the list. They take aspects of several different types of caches and join them together to make a cache that everyone can participate in and enjoy. But how do they work? First, we need to establish what they are… Pict-o-caches are a class on their own. Taking cues from multi-caches, on-site puzzles, and visual puzzles, these puzzles definitely require an observant eye.
