WebMar 20, 2024 · Video. 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. The table consists of the alphabets ... Web(26 factorial, where factorial means multiplying all the whole numbers less than 26) possible keys for this cipher. This is a deceptively large number for its appearance. In fact: 26! = 403,291,461,126,605,635,584,000,000. This is an absurdly large number. If every person on earth (say 8 billion) was to try one key a second, then it would still ...

WebApr 1, 2012 · In short, you need to get the unicode for a character, subtract some offset, multiply by 2, add 2 and take the mod of that number mod 26 to encipher something. To reverse the process, multiply the ciphertext, minus 1, by the modular inverse, add the offset and convert back to a character. Share. Improve this answer.
