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 1 would encode an A as a B, an M as an N, and a Z as an A, and so on. The method is named after Roman …

WebPorta Cipher : Porta cipher is a polyalphabetical cipher which was created by an Italian physicist named Giovanni Battista Della Porta, back in 1563. This cipher was the first one to use multiple alphabets and change it for each letter to encrypt. This makes the Porta cipher really secure in comparison to other ciphers.
