Counter Mode (CTR)Nonce encrypted XOR Block 1 = Cipher 1, Nonce +1 encrypted XOR block 2 = Cipher 2 Rainbow TableA table of hash values and their corresponding plaintext values that can be used to look up password values if an attacker is able to steal a system's encrypted password file.HMACa fixed length string of bits similar to other hashing algorithms such as MD5 and SHA-1, but it also uses a secret key to add some randomness to the result.Pigpen Ciphera geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid Rail Codescrambles text by writing it across rows and columns bifid ciphermaps letters in a grid to numeric values Playfair CipherUses a 5x5 table and a key word. Rest of the alphabet is placed on table in alphabetic order, skipping letters used in the keyword. You break up the message into two character chunks and return a single character value. If the letters appear on the same row of your table, replace them with the letters to the right. If it is on the same column, replace them with the letters below.Morse Codea system of dots and dashes that represent the alphabet Ceasar Ciphera technique for encryption that shifts the alphabet by some number of characters Viginere Cipherusing a series of different monoalphabet ciphers selected based on the letters of a keyword. A polyalphabetic cipher.One-time padan example of perfect (unbreakable) encryption, which is achieved by using, only once, a random polyalphabetic key that is as long the message itself.Four-Square Cipherfour squares of alphabet are created and two characters of plain text are mapped to two characters of cipher text Enigma MachineAn example of a one time pad encryption device.Data Encryption Standard (DES)Symmetric, Block size: 64, Key size: 56, Rounds: 16 Triple Data Encryption Standard (3DES)Symmetric, Block size: 64, Key size: 112, Rounds: 48 Advanced Encryption Standard (AES)Symmetric, Block size: 128, Key Size: 128,192,256, Rounds: 10, 12, 14 International Data Encryption Algorithm (IDEA) Symmetric, Block Size: 64, Key Size: 128, Rounds: 17+ SkipjackSymmetric, Block Size: 64, Key Size: 80, Rounds: 32 BlowfishSymmetric, Block Size: 64, Key Size: 128, 192, 256, Rounds: 16
