Now that we’ve talked about security in general, there’s one more security concept that we need to cover before getting into web-specific concepts, and that’s cryptography. Cryptography is the study of creating codes that protects information. There have been many cryptographic algorithms used throughout history, from one of the earliest-known Caesar cipher, which involves shifting the alphabet X characters over (e.g., shifting “abcdef” two characters over would result in “cdefgh”), to the RSA algorithm used for asymmetric encryption. Rather than try to give a comprehensive treatment to cryptography ...
