Primary task: FOLLOW INSTRUCTIONS: NO PLAGIRMS: ON TIME

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.’

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.
