End-To-End RSA-Encrypted Two-Way Communication
I. Introduction
From the essay
RSA (Rivest-Shamir-Adleman) is one of the most widely used public-key encryption algorithms used for end-to-end encrypted communication. It enables secure digital communication through mathematical operations that are easy to compute in one direction (multiplying large primes) but hard to reverse (factoring the product). RSA provides secure encryption, digital signatures, and safe key exchange between parties who do not need to meet in person.
