Rust SSL

Open-source Rust projects categorized as SSL

An SSL is security technology. It's a protocol for servers and web browsers that makes sure that data passed between the two are private. It was first developed by Netscape in 1995 for the purpose of ensuring privacy, authentication, and data integrity in Internet communications. SSL is the predecessor to the modern TLS encryption used today.
