LibreSSL is an open-source implementation of the Transport Layer Security (TLS) protocol. The implementation is named after Secure Sockets Layer (SSL), the deprecated predecessor of TLS, for which support was removed in release 2.3.0.
Several versions of the TLS protocol exist. SSL 2.0 is a deprecated [27] protocol version with significant weaknesses. SSL 3.0 (1996) and TLS 1.0 (1999) are successors with two weaknesses in CBC-padding that were explained in 2001 by Serge Vaudenay. [28]
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols.
Locating the version of the browser you're using is often the first step when attempting to troubleshoot and fix browser problems. Once you find your browser version, you can use that info to check if you're running the latest software. If not, you can update to the latest version to make sure everything runs the way it's supposed to.
In 2006, this patch was then ported to the development branch of OpenSSL, and in 2007 it was back-ported to OpenSSL 0.9.8 (first released in 0.9.8f [38]). First web browsers with SNI support appeared in 2006 (Mozilla Firefox 2.0, Internet Explorer 7), web servers later (Apache HTTP Server in 2009, Microsoft IIS in 2012).
