About

Secret agents use encryption all the time. You know that everything can be encrypted as different characters. What about encryption that uses only one character and space? This method has a name — the Chuck Norris cipher. In this project, you will create a program that can encrypt any text into a sequence of zeros and spaces and decrypt this sequence into text.

During this project, I learned how to implement the Chuck Norris cipher in Kotlin by converting text to 7-bit binary, grouping repeated bits, and building the encoded block format. I gained practice with Kotlin basics like `while` loops, `StringBuilder`, string trimming, case handling, and parsing i ...
