What is the difference between OpenSSL and TLS?

TLS stands for Transport Layer Security and started with TLSv1. 0 which is an upgraded version of SSLv3. Those protocols are standardized and described by RFCs. OpenSSL provides an implementation for those protocols and is often used as the reference implementation for any new feature.

How do I enable GnuTLS?

Take the following additional steps to deploy GnuTLS certificates on the Apache webserver.

1. Ensure the OpenSSL module is disabled: $ sudo a2dismod ssl.
2. Install the GnuTLS Apache module: $ sudo apt-get install libapache2-mod-gnutls.
3. Make sure the GnuTLS Apache module is enabled: $ sudo a2enmod gnutls.
