Cryptography - The science of altering communication so that it cannot be understood without having the key. cipher - The algorithm(s) needed to encrypt and decrypt a message. Mono-alphabet substitution - Substitute one character of cipher text for each character of plain text. Caesar cipher - Every letter is shifted a fixed number of spaces to the left or the right in the alphabet. Ciphertext - The resultant text after being subjected to the algorithm and key. Atbash Cipher - Reverses the...

Cryptography - science of altering communication so that it cannot be understood without having the key Mono-Alphabet Substitution - algorithms simply substitute one character of cipher text for each character of plain text. Caesar Cipher - choose a number by which to shift each letter of a text. ATBASH Cipher - Hebrew code substitutes first letter of alphabet for last, second letter for the second-to-the-last ROT13 Cipher - characters rotated 13 characters Scytale - Greek, written acros...
