Discussion:
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?
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.'
• Vyc Kbugecgx Qkgftk kcj btosnfntw pa dyiasorrxvwce Zatwuv bt Owivltks ke rwx 16hj tccmitp
3. Create a Vigenère cipher of your own and see who can crack it! Toward the end of the week, provide the solution to your cipher.
Peer Response(s): Read the responses from your peers, attempt to crack the cipher codes presented and offer a constructive critique or additional information that adds substantively to the discussions. Be sure to acknowledge any outside sources you use.
