Discussion on the vigenère cipher.
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?
Try your hand!
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.’
