mod_ssl - SSL/TLS Integration and Interface
Since Apache 1.3, src/modules/ssl/mod_ssl.c (third-party)
Ralf S. Engelschall (1998)
The mod_ssl third-party module provides strong cryptography for Apa==che via the Secure Sockets Layer (SSL version 2/3) and Transport Layer Security (TLS version 1) protocols with the help of the SSL/TLS implementation toolkit OpenSSL. SSL/TLS is a generic cryptography protocol that resides on top of TCP/IP (but below protocols like HTTP) and is used inside web servers to provide the HTTPS protocol (which mainly is HTTP over SSL/TLS over TCP/IP). The mod_ssl module here forms the essential glue code between the OpenSSL toolkit and the Apache web server.
