RSA Algorithm - Unlocking the Magic Behind Secure Communication

In today’s digital age, secure communication is paramount. The RSA algorithm, named after its creators Ron Rivest, Adi Shamir, and Leonard Adleman, is one of the most widely used asymmetric encryption algorithms. The RSA algorithm is based on the mathematical principles of modular arithmetic and the difficulty of factoring large numbers. In this paper, we will discuss how the RSA algorithm works, its strengths, and limitations.

Modular Arithmetic

Modular arithmetic is a type of arithmetic that involves integers and their remainders. It is a fundamental concept used in the RSA algorithm. Let’s take an example, say we want to calculate 17 mod 5. This means we want to find the remainder when 17 is divided by 5. The answer is 2. The modulo operation returns the remainder after dividing the number by another number. In the RSA algorithm, modular arithmetic is used to generate public and private keys.
