WebAn affine cipher, (like a shift cipher), is an example of a substitution cipher: In encryption using a substitution cipher, each time a given letter occurs in the plaintext, it always is replaced by the same ciphertext letter. For example, the plaintext letter ‘e’ might be replaced by the ciphertext letter ‘K’ each time it occurs.

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. WebThe meaning of CRYPTOGRAPHY is secret writing.
