Caesar ciphers use a substitution method where letters in the alphabet are shifted by some fixed number of spaces to yield an encoding alphabet. A Caesar cipher with a shift of 1 would encode an A as a B, an M as an N, and a Z as an A, and so on.

WebElectronic Code Book (ECB) is a simple mode of operation with a block cipher that's mostly used with symmetric key encryption.
