Introduction to Encryption and Cryptography

This online course from the Raspberry Pi Foundation explores encryption and cryptography. You'll learn about what encryption is and how it was used in the past, and use the Caesar and Vigenère ciphers. You'll also look at modern encryption, and investigate both symmetric and asymmetric encryption schemes. The course also takes a look at the future of encryption, and includes several practical encryption activities that are also appropriate to use in the classroom.

The course will cover:

• A brief look at the history of encryption
• The encryption and decryption process, and the importance of keys
• The Caesar and Vigenère ciphers
• Symmetric and asymmetric encryption schemes
• Public-key encryption in the real world
• An introduction to quantum cryptography
• Practical encryption activities
