WebVigenere Cipher Cryptanalysis. The Vigenere Cipher initially seems very secure, however it can be broken fairly easily once the length of the keyword is known. If you know that the length of the keyword is n, you can break the ciphertext into n cosets and attack the cipher using frequency analysis if the ciphertext sample is long enough. ...
