WebSep 12, 2024 · Download chapter PDF. This chapter provides an introduction to classic cryptography. It explains the symmetric class of ciphers, whereby the encryption key is the same for both operations—encryption and decryption. Such ciphers are Caesar, Vigenère, Hill, and others. WebHill cipher is one of the techniques to convert a plain text into ciphertext and vice versa. There are two parts in the Hill cipher – Encryption and Decryption. Encryption – Plain text …
