Introduction to Encryption and Cryptography
Discover the history of encryption and learn how it's used in the modern world
On this course, you will learn about what encryption is and understand its use in the past by using the Caesar and Vigenère ciphers.
You will also look at the present and future of encryption and investigate both symmetric and asymmetric encryption schemes.
The course includes several practical encryption activities which you can complete and use in your own classroom.
