Apache HTTPD mod_ssl
Apache HTTPD mod_ssl is a module that provides support for secure communication via the SSL/TLS protocols in the Apache HTTP Server (HTTPD). It enables the server to encrypt data transmitted between clients and the server, ensuring confidentiality, integrity, and authenticity of communication over the internet. Mod_ssl allows administrators to configure SSL/TLS certificates, cryptographic protocols, and encryption algorithms to secure HTTPD connections. Additionally, it supports features such as client certificate authentication, session caching, and OCSP stapling, enhancing security and performance. Mod_ssl is commonly used to enable HTTPS (HTTP over SSL/TLS) on web servers, securing sensitive data transmission, user authentication, and online transactions. It is an essential component for deploying secure websites, web applications, and services on the Apache HTTP Server. s://httpd.apache.org/docs/2.4/mod/mod_ssl.html
