WebMar 20, 2024 · Vigenere Cipher is a method of encrypting alphabetic text. It uses a simple form of polyalphabetic substitution. A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The encryption of the original text is done using the Vigenère square or Vigenère table.

WebSubstitution methods are based on a tabular assignment of plaintext characters and ciphers in the form of a secret code book . One of the first and easiest encryption methods of this type goes all the way back to Julius Caesar. The so-called Caesar cipher is based on monoalphabetic substitution. WebIn cryptography, a substitution cipher is a method of encoding by which units of plaintext are replaced with ciphertext, according to a regular system; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. There are a number of different types of substitution cipher. One type of substitution …
