Q: Why is FLT important in cryptography?

In recent years, modular arithmetic has been gaining attention in various fields, from cryptography to coding theory. One of the key factors driving this interest is Fermat's Little Theorem (FLT), a fundamental principle that helps us understand the properties of modular arithmetic. As researchers and developers explore new applications of modular arithmetic, FLT is playing a crucial role in unlocking its secrets. This article delves into the world of FLT, exploring its concepts, applications, and implications.
