SSL (Secure Sockets Layer) is a cryptographic protocol developed by Netscape in the 1990s to provide secure communications over the internet. SSL has been deprecated and replaced by TLS (Transport Layer Security), but the term 'SSL' is still commonly used to refer to TLS certificates and secure connections. SSL/TLS certificates are issued by Certificate Authorities (CAs) and enable HTTPS, encrypting data between clients and servers and authenticating server identity.
