Known-plaintext attack — The known plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has samples of both the plaintext (called a crib), and its encrypted version (ciphertext). These can be used to reveal further secret information such as… … Wikipedia
Substitution cipher — In cryptography, a substitution cipher is a method of encryption by which units of plaintext are replaced with ciphertext according to a regular system; the units may be single letters (the most common), pairs of letters, triplets of letters,… … Wikipedia
Beaufort cipher — The Beaufort cipher, created by Sir Francis Beaufort, is a substitution cipher that is similar to the Vigenère cipher but uses a slightly modified enciphering mechanism and tableau.Using the cypherTo encrypt (or decrypt for that matter), first… … Wikipedia
One-time pad — Excerpt from a one time pad In cryptography, the one time pad (OTP) is a type of encryption, which has been proven to be impossible to crack if used correctly. Each bit or character from the plaintext is encrypted by a modular addition with a bit … Wikipedia
Unicity distance — is a term used in cryptography referring to the length of an original ciphertext needed to break the cipher by reducing the number of possible spurious keys to zero in a brute force attack. That is, after trying every possible key, there should… … Wikipedia

Cryptanalysis of the Enigma — enabled the western Allies in World War II to read substantial amounts of secret Morse coded radio communications of the Axis powers that had been enciphered using Enigma machines. This yielded military intelligence which, along with that from… … Wikipedia
Two-square cipher — The Two square cipher is a manual symmetric encryption technique. It was developed to ease the cumbersome nature of the large encryption/decryption matrix used in the four square cipher while still being slightly stronger than the Playfair cipher … Wikipedia

Four-square cipher — The Four square cipher is a manual symmetric encryption technique. It was invented by famous French cryptographer Felix Delastelle.The technique encrypts pairs of letters ( digraphs ), and thus falls into a category of ciphers known as… … Wikipedia
Running key cipher — In classical cryptography, the running key cipher is a type of polyalphabetic substitution cipher in which a text, typically from a book, is used to provide a very long keystream. Usually, the book to be used would be agreed ahead of time, while… … Wikipedia
