Cryptography letters
WebEncryption. Encryption using the Shift Cipher is very easy. First we must create the ciphertext alphabet, which as discussed above is simply found by 'shifting' the alphabet to the left by the number of places given by the key. Thus a shift of 1 moves "A" to the end of the ciphertext alphabet, and "B" to the left one place into the first position. Web1:46. For a polyalphabetic cypher Brit explains that the length of the word is the key in a cracking the code. To find this you take letters at different intervals to build a subset of …
