WebbVigenère cipher: Encrypt and decrypt online. Method of encrypting alphabetic text by using a series of interwoven Caesar ciphers based on the letters of a keyword. Though the 'chiffre indéchiffrable' is easy to understand and implement, for three centuries it resisted all attempts to break it. MD5 hash. ADFGVX. WebbThe Keyword cipher is identical to the Caesar Cipher with the exception that the substitution alphabet used can be represented with a keyword. To create a substitution …

The difference lies in how the key is chosen; the Vigenère cipher uses a short key …
WebbThe primary weakness of the Vigenère cipher is the repeating nature of its key. If a cryptanalyst correctly guesses the key's length, then the ciphertext can be treated as interwoven Caesar ciphers, which individually are easily broken. The running key variant of the Vigenère cipher was also considered unbreakable at one time.
WebbA book cipher, or Ottendorf cipher, [citation needed] is a cipher in which the key is some aspect of a book or other piece of text. Books, being common and widely available in modern times, are more convenient for this use than objects made specifically for cryptographic purposes.
