SSL and TLS Basics

What is SSL and TLS Basics?
Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols that provide secure communication over a network. They work by encrypting data exchanged between a client and a server, ensuring confidentiality and integrity. SSL was the predecessor to TLS, and while SSL is now considered outdated and insecure, the term "SSL" is often still used interchangeably with "TLS." The protocols establish a secure connection using digital certificates for authentication and encryption algorithms for data protection.
