WebSSL and TLS are cryptographic protocols that provide authentication and data encryption between servers, machines, and applications operating on a network. The first iteration of SSL, version 1.0, was developed in 1995 by Netscape. Then, SSL 1.3 was finalised in 2024 after 11 years and nearly 30 IETF drafts. SSL 2.0 wasn’t a whole lot better.
