While we would like to think that we have discovered every living thing on this planet, we have only skimmed the surface. This means that when we do see something that is truly out of this world, headlines are made and everyone gets out their cameras for a picture. Speaking of cameras, they are everywhere these days! From phones to satellite imagery to surveillance cameras, you can always get a picture of yourself if you need one! So, when you think about it, it’s easier than ever to get a picture or video or a mysterious creature. But, even with technology as advanced as it is, we can still get freaked out when we see something we’re not familiar with. These days, more creatures are being discovered than ever. No longer are they myth or legend. Instead, they are proving that they are very much as real as you and me!

Uncrackable Pen & Paper Cryptography
Why there is always a safe place for PEOPLE to communicate. P.S. 1. Yes, this is just a "one time pad", and using each key only once is crucial. 2. Yes, this is uncrackable. Without the key you cannot get the message. Brute force does not work as it gives all possible messages and does not say which is the one being sent. 3. Yes, random numbers do exist, but for this a pair of dice is more than adequate.

The Enigma Machine Explained
As technology increases, so do the methods of encryption and decryption we have at our disposal. World War II saw wide use of various codes from substitution ciphers to employing Navajo code talkers in the Pacific theater. Here, science journalist and author Simon Singh demonstrates the German enigma machine, a typewriter-like device used to encrypt communications. He demonstrates not only its operation, but both the strength and fatal flaws in its method.

In the quantitative aptitude section of the eLitmus pH test and Infosys Aptitude Test mathematical reasoning section, 1 or 2 questions will be on the topic Cryptarithmetic. What is cryptarithmetic? This topic involves just basic addition and subtraction, but it’s not easy to solve without practice. There will be two words which will be added or subtracted to get another word and all the alphabets of these words will be coded with a unique number. You will have to find all the unique numbers as coded and we have to answer the given question. Cryptarithmetic is easy if you understand the basics clearly and practice more problems.

Cryptography: Codes, Ciphers, and Connections
The encryption of information is as old as information itself. Ever since two people wanted to pass something along, so has there been a third party who wanted to be privy to it. This back and forth battle of creating codes, breaking them, and finding new ones has been happening quietly for thousands of years. Now, in an age when information flows freely and instantaneously, the field of cryptography is more important than ever.

Cipher Feedback Mode(CFB) | Algorithm Modes in Cryptography
In this network security video tutorial we will study and understand the working of Cipher Cipher Feedback (CFB) also known as CFB algorithm mode. Cipher Feedback (CFB) - 1. In this mode data is encrypted in units that are smaller (e.g. they could be of size 8 bits) than a defined block size (which is usually 64 bits). 2. CFB mode works with j bits at a time (as we have seen, usually, but not always , j = 8) Following are the steps of CFB mode - Step 1 - Encrypt the IV(initialization vector) using the KEY to get the Encrypted IV. Step 2 - Perform XOR operation between first j bits of encrypted IV and j bits of Plain Text to get j bits of Cipher Text(Cipher text block 1) Step 3 - left shift the IV by j bits & add the cipher text block from the previous step to the right most side of the IV.

5 Reasons Why I Love Cryptography By Susan Freed In Atlanta
Five Reasons Why I Love Cryptography http://iheartsusanfreed.com For years, I didn't know anything about cryptography. I'd heard the term, but I didn't know what it meant, or what the practice involved. Still, when I got the chance to study cryptography, I took it, and my life has been richer and more interesting as a result. Cryptography is essentially the study of codes, and learning more about it can benefit your life in all kinds of ways. Below, you'll find five of the reasons I love cryptography. If you learn more about it, there's a good change you'll wind up loving cryptography as much as I do. 1. It makes life more interesting Ever since I started studying cryptography, I've begun to see codes and hidden messages in everything. When I read a letter or look at a sign, I automatically start making connections with my mind. There probably aren't any hidden messages in road signs, but that doesn't matter! Thinking about those things makes my life a lot more interesting, and a lot more fun. 2. It's made me smarter Cryptography is a great way to train your mind and make it sharper than ever before. It helps to improve your concentration as well as your wit. Since I started studying cryptography, I get better scores on tests, and have an easier time studying for classes at school. It's really strengthened my mind. 3. It's given me a more well-rounded education Because of my interest in cryptography, I've studied a number of other subjects. It's given me reason to improve my math and science skills, and to study all kinds of history. I'm more motivated to learn than ever before, and that's helped to educate me in some very interesting ways. Cryptography has given me a better education than I ever would have had without it. I feel like I have little bits of knowledge in all kinds of subjects, and that's really exciting. 4. It's helped me meet some amazing people Because of my passion for cryptography, I've made connections and met people from all over the world. Many of these people are just as passionate about cryptography as I am, and many of them are amazing. The field of cryptography attracts some fascinating and brilliant people. I'm grateful to have met all of them, and I'm very glad that it was cryptography that managed to bring us together. 5. It's a ton of fun! While all of the benefits above are nice, the real reason I love cryptography is that it's fun. No TV show or movie is as exciting as solving a mystery or cracking a puzzle on your own. Cryptography isn't an expensive hobby, but it's definitely an entertaining one. Every day, I always have something interesting to do, and I owe that to cryptography. I highly recommend that everyone learns more about cryptography. It's amazing for more than five reasons, and if you look into it, you'll probably love it too. Cryptography is an absolutely incredible hobby. http://youtu.be/TXplWR7Jr-E http://en.wikipedia.org/wiki/Cryptography

Caesar Cipher | Caesar Substitution Cipher | Cryptography series | Eng - Hindi | Tutorial-1
#AskFaizan | #syedfaizanahmad Playfair Substitution Cipher https://youtu.be/w_xr7pj-O6c Monoalphabetic Substitution Cipher https://youtu.be/Hw1T7GOnVW0 Caesar Cipher | Caesar Substitution Cipher https://youtu.be/2N9GlhysYJw PlayList : Cryptography and Network Security : https://www.youtube.com/playlist?list=PLhwpdymnbXz7hvvqhqjIIG4tEdhAgQqll The Caesar cipher is one of the earliest known and simplest ciphers. It is a type of substitution cipher in which each letter in the plaintext is 'shifted' a certain number of places down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on. The method is named after Julius Caesar, who apparently used it to communicate with his generals. The algorithm can be expressed as For each plaintext letter p , substitute the ciphertext letter C C = E(k, p) = (p + k) mod 26 Where k takes on a value in the range 1 to 25. The decryption algorithm is simply p = D(k, C) = (C - k) mod 26 Drawbacks - Caesar Cipher is one of the weakest forms of encryption as The key space is very small. Using a brute force attack method, one could easily try all (25) possible combinations to decrypt the message without initially knowing the key. The language of the plaintext is known and easily recognizable. Cryptanalysis: Cryptanalytic attacks rely on the nature of the algorithm plus perhaps some knowledge of the general characteristics of the plaintext or even some sample plaintext–ciphertext pairs. Brute-force attack: The attacker tries every possible key on a piece of ciphertext until an intelligible translation into plaintext is obtained. On average, half of all possible keys must be tried to achieve success. #askfaizan | #syedfaizanahmad

This footage shows a three rotor German Enigma machine invented by the German engineer Arthur Scherbius at the end of World War I. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. Several different Enigma models were produced, but the German military models are the most commonly recognized. German military messages enciphered on the Enigma machine were first broken by the Polish Cipher Bureau, beginning in December 1932. This success was a result of efforts by three Polish cryptologists, Marian Rejewski, Jerzy Różycki and Henryk Zygalski, working for Polish military intelligence. Rejewski reverse engineered the device, using theoretical mathematics and material supplied by French military intelligence. Subsequently the three mathematicians designed mechanical devices for breaking Enigma ciphers, including the cryptologic bomb. From 1938 onwards, additional complexity was repeatedly added to the Enigma machines, making decryption more difficult and requiring larger numbers of equipment and personnel -- more than the Poles could readily produce. On 25 July 1939, in Warsaw, the Poles initiated French and British military intelligence representatives into their Enigma-decryption techniques and equipment, including Zygalski sheets and the cryptologic bomb, and promised each delegation a Polish-reconstructed Enigma. The demonstration represented a vital basis for the later British continuation and effort. During the war, British cryptologists decrypted a vast number of messages enciphered on Enigma. The intelligence gleaned from this source, codenamed "Ultra" by the British, was a substantial aid to the Allied war effort. Though Enigma had some cryptographic weaknesses, in practice it was German procedural flaws, operator mistakes, laziness, failure to systematically introduce changes in encipherment procedures, and Allied capture of key tables and hardware that, during the war, enabled Allied cryptologists to succeed We encourage viewers to add comments and, especially, to provide additional information about our videos by adding a comment!

Kya hai cryptography ? | Explained in simple words with good examples | basic concept
All about cryptography and information security which a computer graduate must know. Cryptography or cryptology is the practice and study of techniques for secure communication in the presence of third parties called adversaries. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages;[3] various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation[4] are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include military communications, electronic commerce, ATM cards, and computer passwords. Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message (Alice) shared the decoding technique needed to recover the original information only with intended recipients (Bob), thereby precluding unwanted persons (Eve) from doing the same. The cryptography literature often uses Alice ("A") for the sender, Bob ("B") for the intended recipient, and Eve ("eavesdropper") for the adversary. Since the development of rotor cipher machines in World War I and the advent of computers in World War II, the methods used to carry out cryptology have become increasingly complex and its application more widespread. Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary. It is theoretically possible to break such a system, but it is infeasible to do so by any known practical means. These schemes are therefore termed computationally secure; theoretical advances, e.g., improvements in integer factorization algorithms, and faster computing technology require these solutions to be continually adapted. There exist information-theoretically secure schemes that provably cannot be broken even with unlimited computing power—an example is the one-time pad—but these schemes are more difficult to implement than the best theoretically breakable but computationally secure mechanisms. The growth of cryptographic technology has raised a number of legal issues in the information age. Cryptography's potential for use as a tool for espionage and sedition has led many governments to classify it as a weapon and to limit or even prohibit its use and export.In some jurisdictions where the use of cryptography is legal, laws permit investigators to compel the disclosure of encryption keys for documents relevant to an investigation.Cryptography also plays a major role in digital rights management and copyright infringement of digital media.

Cool Codes for Kids: The Pigpen Cypher
Dan Metcalf, author if Codebusters, gives you the lowdown on codes, ciphers and puzzles you can try at home. What do you do when you want all your writing to be secret? You use a code of course. You could use a substitution code like the Caesar shift, but you can just as easily use a code that substitutes letters for shapes. This is what the Freemasons did a few hundred years ago when they invented the Pigpen cypher! To start, you need a key – use two grids like this – the 'pigpen' – and fill in the alphabet. The second grids have dots in them so you can tell them apart from the first ones. Then you take the individual shape of the letter you wish to replace and copy it down. Then the decoder just needs to match the shapes to their key. Nifty, huh? Try this yourself!

CppCon 2018: Fabian Renn-Giles “A Semi Compile/Run-time Map with (Nearly) Zero Overhead Lookup”
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — An associative map container is one of the most useful data-structures in any modern program. Given a key, it can look-up the corresponding value incurring some runtime overhead. Often, however, this overhead is not strictly necessary as the key originated (either directly or indirectly) from a value which was known to the compiler at compile-time - such as a literal. In this talk, I will present a semi compile-/run-time map which can overcome this overhead by using C++’s constexpr features. Yet another constexpr hash map talk, I hear you say? This one is different! Most constexpr maps presented at previous conferences are either constexpr-only, i.e. the values cannot be changed at runtime, or, require that all possible keys of the map are defined in one place making it unsuitable for library code. In contrast, the map presented in this talk, only calculates the storage of the key’s associated value at compile-time, but loading/storing the value and adding key/value pairs still occurs at run-time. It will be shown how such a map can be used to implement a super efficient cache. In its most simplest form, looking up the storage of a primitive type for a given compile-time key has the same overhead as accessing a global variable. It will be shown that the underlying principle is surprisingly easy (3 lines of code) and the difficulty actually lies in associating any compile-time identifier to a unique C++ type - especially string literals. I will show how this can be achieved using constexpr if and constexpr lambda expressions - both C++17 features. — Fabian Renn-Giles, Fielding DSP Senior Software Engineer Fabian Renn-Giles (PhD) is a freelance C++ programmer, entrepreneur and consultant in the audio software industry. Up until recently he was staff engineer at ROLI Ltd. and the lead maintainer/developer of the JUCE C++ framework (www.juce.com) - an audio framework used by thousands of commercial audio software companies. Before joining ROLI, he completed his PhD at Imperial College London, developing a numerical quantum optics solver with modern digital signal processing techniques and C++/MPI/OpenCL. During his academic career, Fabian regularly taught C++ to post- and undergraduate students in tutor groups. In 2005, Fabian co-founded the audio plug-in start-up Fielding DSP which specialises in real-time audio plug-ins for audio mastering. Fabian now regularly consults on various audio related software projects. Additionally, he is a regular speaker and/or workshop leader at the C++ audio developer conference ADC. He also hosts the monthly audio developer meetup in London. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com
