Web5. A Vigenère cipher is easily breakable, when the ciphertext is reasonably larger than the key size. This is due to the fact that its cipher-texts leak statistical information about the pair plaintext - key. Applying a Vigenère cipher several times, with different keys and key-sizes, would not make your scheme much more secure. WebApr 6, 2024 · Star 11. Code. Issues. Pull requests.
