Cryptography, Day 2

Hopper section: Friday, May 1, Lovelace section: Monday, May xx.

Plan for the Day

• Opening circle
• Online post-survey (20-30 minutes) (instructions). Our club id# is 542.
• Review cryptography lesson
• Basic flow of encryption and decryption
• How Ceaser cipher works
• How Vigenère cipher works
• Level 1
  • Continue cryptography assignment: Ceaser cipher , two helper functions.
• Level 2
  • Introduce JSFiddle encryptor/decryptor sample. Students are encouraged to clone and extend this instead of working in KhanAcademy JavaScript.

• Continue cryptography assignment: Vigenère cipher
• Closing circle
