This article guides you through the vital process of setting up TLSv1.2 on CentOS, a critical step in fortifying the security of your server communications. As an integral component of secure data transmission, Transport Layer Security (TLS) ensures data confidentiality and integrity. Whether you’re a system administrator or a user keen on enhancing your CentOS server’s security, this concise yet comprehensive guide equips you with the knowledge and steps necessary to implement TLSv1.2 effectively, elevating the safeguarding of your data against potential threats.<\/p>\n

TLSv1.2 should be available on CentOS 6.5. You can test if your website supports TLSv1.2 by running the following command from your local machine:<\/span><\/p>\n

openssl<\/span> s_client<\/span> -connect<\/span> your<\/span>.domain.name<\/span>:443<\/span> -tls1_2<\/span><\/code><\/span><\/pre>\n
You should see something like:<\/span><\/p>\n
SSL-Session<\/span>:    Protocol<\/span>  : TLSv1<\/span>.2<\/span>    Cipher<\/span>    : AES256-SHA256<\/span><\/code><\/span><\/pre>\n
More important than the operating system, however, is the version of OpenSSL you are using. You will just want to make sure you are using OpenSSL 1.0.1 or later. OpenSSL 0.9.8 does not support TLS 1.2. You can confirm this at the\u00a0OpenSSL changelog<\/a>. To check which version of OpenSSL you are running, you can run the following commands:<\/span><\/p>\n
openssl<\/span> version yum info<\/span> openssl\n<\/code><\/span><\/pre>\n
To download, compile, and install the latest version of OpenSSL, you can run the following commands:<\/span><\/p>\n
#Downloads the latest version<\/span>\ncd<\/span> \/usr\/src wget https:\/\/www.openssl.org\/source<\/span>\/openssl-1.0.2-latest.tar.gz tar -zxf openssl-1.0.2-latest.tar.gz \n#Manually compiles OpenSSL and upgrades OpenSSL<\/span>\ncd<\/span> openssl-1.0.2a .\/config make make test<\/span>\nmake install \n#If you are still seeing the old version still displayed, make a copy of the Open SSL bin file<\/span>\nmv \/usr\/bin\/openssl \/root\/ ln -s \/usr\/local<\/span>\/ssl\/bin\/openssl \/usr\/bin\/openssl\n<\/code><\/span><\/pre>\n
From there you can run the\u00a0openssl version<\/code> command again to verify it has installed\/updated properly. Hope this helps point you in the right direction!<\/span><\/p>\n<\/article>\n
Frequently asked questions:<\/p>\n
Why is setting up TLSv1.2 important for CentOS?<\/strong><\/p>\n
IImplementing TLSv1.2 on CentOS is crucial for enhancing the security of server communications. TLS ensures encrypted data transmission, protecting against potential threats such as eavesdropping and tampering. TLSv1.2 specifically addresses vulnerabilities found in earlier versions, making it a recommended choice to ensure a robust and secure environment for data exchange.<\/p>\n","protected":false},"excerpt":{"rendered":"
