WebJul 1, 2024 · Public-key encryption where each party (whether it is a user, program or system) involved in the communication has two keys, one public and one private that must be kept secret. An example of this type is using SSL/TLS certificates (HTTPS) that are used to ensure the validity of machine identities between a web server and someone’s browser. WebDec 9, 2012 · Caesar’s cipher would encode A as D, B as E, C as F, and so forth. It would encode W as Z, X as A, Y as B, and Z as C, as well. So, for example, we would encode the message, “Meet me at the restaurant” as “Phhw ph dw wkh uhvwdxudqw”, simply by taking each letter in the message and encoding it as the third letter after it.
