The Vigenère Cipher
Primary Task Response:
Please provide a detailed response to the below to include specific details and examples.
What is the Vigenère Cipher?
How does it work?
Although the Vigenère cipher was an improvement upon previous historical encryption techniques, it is still vulnerable. How would an attacker break a Vigenère-style cipher?
1. Encrypt the below message using the Vigenère cipher.
NOW IS THE TIME FOR ALL GOOD MEN TO COME TO THE AID OF THEIR COUNTRY.
2. Decrypt the below message using the Vigenère cipher. The passphrase is ‘crypto.'
