Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

The simplest mode of operation 2. Plain text message is divided into blocks of 64 bits each. 3. Each such block is encrypted independently of the other blocks. 4. For all blocks same key is used for encryption. 5. If a plain text block repeats in the original messages, the corresponding cipher text block will also repeat in the encrypted message. 6. Suitable only for small messages.

The ATBASH cipher actually got it's start in Hebrew text - notably in Jewish Mysticism, as it's used in translations of their religious books. The name itself is is actually an acronym of four Hebrew letters: Aleph-Tav-Beth-Shin (אתבש). The way the Atbash Cipher works is by mirroring the alphabet. By writing A to Z on a piece of paper and Z to A just below it, you've crafted an Atbash Cipher! This means that if you decode one letter B=Y, you've decoded the reverse as well Y=B. Due to the low difficulty of this encryption method, it's not often used in situations where data must remain secure - but it does make a great way to casually encode messages between friends! http://wp.me/a4aWg3-8H

Caesar Cipher Encryption and Decryption in C++
 
12:13
Ceasar Cipher in c++ Hi!! In this video I'll be doing ceasar cipher encryption and decryption using C++ Caesar Cipher is subsitution cipher, its algorithm is as following: - Take alphabetic message (A to Z) - Take a key (1 to 26) (1 being A and 26 being Z) - To encrypt, left-shift or right-shift message letter by letter by the value of key For example if message is "ABC" and key is 1 and we are performing right-shift then encrypted text will be A+1 = B, B+1 = C, C+1 = D. ABC = BCD, BCD being encrypted text. - To decrypt, left-shift or right-shift the message letter by letter opposite to the shift performed in encryption by the value of key For example if encrypted text is "BCD" and key is 1 and we are performing left-shift then encrypted text will be B-1 = A, C-1 = B, D-1 = C. BCD = ABC, ABC being decrypted text.

What is Book cipher? Explain Book cipher, Define Book cipher, Meaning of Book cipher
 
01:23
~~~ Book cipher ~~~ Title: What is Book cipher? Explain Book cipher, Define Book cipher, Meaning of Book cipher Created on: 2018-08-18 Source Link: https://en.wikipedia.org/wiki/Book_cipher ------ Description: A book cipher is a cipher in which the key is some aspect of a book or other piece of text. Books, being common and widely available in modern times, are more convenient for this use than objects made specifically for cryptographic purposes. It is typically essential that both correspondents not only have the same book, but the same edition.Traditionally book ciphers work by replacing words in the plaintext of a message with the location of words from the book being used. In this mode, book ciphers are more properly called codes. This can have problems; if a word appears in the plaintext but not in the book, it cannot be encoded. An alternative approach which gets around this problem is to replace individual letters rather than words. One such method, used in the second Beale cipher, substitutes the first letter of a word in the book with that word's position. In this case, the book cipher is properly a cipher — specifically, a homophonic substitution cipher. However, if used often, this technique has the side effect of creating a larger ciphertext and increases the time and effort required to decode the message. ------ To see your favorite topic here, fill out this request form: https://docs.google.com/forms/d/e/1FAIpQLScU0dLbeWsc01IC0AaO8sgaSgxMFtvBL31c_pjnwEZUiq99Fw/viewform ------ Source: Wikipedia.org articles, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.

Understand the working of Symmetric Key Cryptography and Asymmetric Key Cryptography in detail with working and difference between the 2 types. Symmetric Key Cryptography(Private Key Cryptography) - 1. In symmetric-key cryptography, the same key is used by the sender (for encryption) and the receiver(for decryption). 2. The key is shared. 3. The key is Secret and kept Private between the Sender & Receiver 4. For N users in a network the number of keys required is - N(N-1)/2 Asymmetric Key Cryptography(Public Key Cryptography) 1. In asymmetric-key cryptography, 2 different keys are used. 1 for Encryption & 1 for Decryption. 2. Every communicating party needs just a key pair. 3. One of the two keys is called as Public Key and the other is the Private Key. 4. Private key remains as a secret. Public key is for the general public. 5. Only the corresponding public private key pair and encrypt and decrypt messages and no other key can be used. 6. For N users in a network the number of keys required is - N*2.
