WebMar 22, 2024 · Authentication: Cipher text can be used to authenticate the sender of a message, as only someone with the appropriate key can transform the cipher text back into plain text. Integrity: Cipher text can be used to verify the integrity of a message, as any changes to the cipher text during transmission will result in an incorrect decryption.

WebThe 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.
