Summary

This hour explained the fundamentals of the SSL protocol and mod_ssl, the Apache module that implements support for SSL. You learned how to install and configure mod_ssl and the OpenSSL libraries, and how to use the openssl command-line tool for certificate and key generation and management. You can access the mod_ssl reference documentation for in-depth syntax explanation and additional configuration information. Bear in mind also that SSL is just part of maintaining a secure server, which includes applying security patches, OS configuration, access control, physical security, and so on.
