It is worth running the make test to see if there are any unexpected errors. shared will force creating shared libraries and Zlib means that compression will be performed by using zlib library. Also set –prefix and –openssldir to the same location.

The behavior and interactions of -prefix and -openssldir are slightly different between OpenSSL 1.0.2 and below and OpenSSL 1.1.0 and above. prefix and -openssldir control the configuration of installed components. After that decompress the file and rename the folder name and navigate to the OpenSSL folder. We downloaded the latest version of OpenSSL which is openssl-1.1.1f at the time of writing this post. config -prefix=/usr/local/openssl -openssldir=/usr/local/openssl -libdir=/lib64 shared zlib-dynamic make -j4 make test make install But the current Nginx version is built with OpenSSL 1.0.2k-fips so first we need to install OpenSSL version 1.1.1 through the compile process and again recompile our Nginx with a new OpenSSL version.Īs we can see below the OpenSSL version is OpenSSL 1.0.2k-fps and Nginx version 1.16.1.Ĭd /usr/src wget tar xvf openssl-1.1.1f.tar.gz mv openssl-1.1.1f openssl cd openssl.

A valid domain name with correctly configured DNS records.Īs we are planning to deploy TLS 1.3 on our production CentOS7 server, we already have a valid domain name, valid TLS certificate, and Nginx version 1.16.1 which is greater than the minimum version required for TLS 1.3.

To enable TLS 1.3 on any distributions please look at the below-required details. But If you want to enable TLS 1.3 then you must fulfill the few requirements. If you download the Nginx from the centos 7 repo you will get Nginx built with OpenSSL 1.0.2k-fips. It is currently supported in both Chrome (starting with release 66) and Firefox (starting with release 60) and in development for Safari and Edge browsers.

It has improved latency over older versions and several new features. TLS 1.3 is the newest and most secure version of the TLS protocol. For a list of vulnerabilities, and the releases in which they were found and fixes, see the OpenSSL Vulnerabilities page.

It is licensed under an Apache-style license, which means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions. OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. Here, we are going to enable TLS 1.3 on CentOS 7.
