In this tutorial, we learned what Caesar Cipher is, how it is easy to implement it in Python, and how its implementation can be further optimized using what we call ‘lookup tables’. Python doesn’t let you perform math operations on letters so you have to use the “ord” function to convert them to the Unicode code point first. This may cause num to be less Firstly, we will try to achieve a brief understanding of what exactly is the concept of cryptography and what are its applications. This lab will work a little differently than previous ones. Skip to content. Caesar used a cypher when he wanted to transmit coded messages on his military campaigns.
