The Top Secret Language of Flowers eyes only; - DO NOT FAX - DocRef# 10.401892.112a-j: The following classified document provides a brief introduction and overview of the top secret language of flowers; while you are in the field, most of the updates regarding your mission status will be delivered in this fashion. Do not reveal or refer to any of this information to anyone not personally known to you and in your division or chain of command. Floral "messages" may be delivered to you at any time during your mission. Always assume that you may be under surveillance by enemy counterintelligence agents and act accordingly. When you receive a coded floral message, respond warmly or otherwise as you deem appropriate.
Sharky's Vigenere Cipher This page is for amusement only. Instructions are given below this form. instructions: Enter the string to encrypt or decrypt in the Input field (you may copy and paste it from another text editor). Enter the key in the Key field. (You may use any sequence of characters, but only alphabetic characters will actually be processed. Enigma Simulator This software is an exact simulation of the 3-rotor Wehrmacht (Heer and Luftwaffe) Enigma, the 3-rotor Kriegsmarine M3, also called Funkschlussel M, and the famous 4-rotor Kriegmarine M4 Enigma cipher machine, used during World War II from 1939 until 1945. The sim has a very authentic feeling with its hands-on approach: you can select between the three models, actually lift out and insert different rotors, adjust their ring setting and set up the plugboard. The internal wiring of all rotors is identical to those that were used by the Wehrmacht and Kriegsmarine. This simulator is therefore fully compatible with the various real Enigma models and you can decrypt authentic wartime messages or encrypt and decrypt your own messages.

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.
Elliptic curve cryptography Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. Elliptic curves are also used in several integer factorization algorithms that have applications in cryptography, such as Lenstra elliptic curve factorization. The use of elliptic curves in cryptography was suggested independently by Neal Koblitz and Victor S. Miller in 1985. Elliptic curve cryptography algorithms entered wide use in 2004 to 2005. Introduction
Nonverbal Communication Communication in general is process of sending and receiving messages that enables humans to share knowledge, attitudes, and skills. Although we usually identify communication with speech, communication is composed of two dimensions - verbal and nonverbal. Nonverbal communication has been defined as communication without words. MP3Stego 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.
National Cryptologic Museum The National Cryptologic Museum is the National Security Agency's principal gateway to the public. It shares the Nation's, as well as NSA's, cryptologic legacy and place in world history. Located adjacent to NSA Headquarters, Ft. George G. practical dream analysis & waking life meaning Drawing by Catherine MacIntyre The above title may seem odd, if not a complete contradiction. Why would anyone suggest that nightmares or anxiety dreams might be helpful? If you're in the half of the population that has experienced an anxiety dream or nightmare within the last month, then this may even be what you're wishing you could get rid of, right?
Cryptography 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.
