A Primer on Public-key Encryption

In this article, the author provides a detailed explanation of public-key encryption, a crucial technology for secure communication over the internet. The article begins by introducing the concept of encryption and the limitations of traditional symmetric encryption methods. It then delves into the workings of public-key encryption, which involves the use of two mathematically related keys - a public key and a private key. The author explains how these keys are generated, how they are used to encrypt and decrypt messages, and how public-key encryption ensures confidentiality, authenticity, and integrity of communications. The article concludes by discussing the implications and challenges of implementing public-key encryption in practice.
