!!! Overview
[{$pagename}] is a [Cryptosystem] which is implemented as an [Open Source] [Software library]


The [OpenSSL Project|http://www.openssl.org/] is a collaborative effort to develop a robust, commercial-grade, full-featured, and [Open Source] toolkit implementing the [Secure Socket Layer] (SSL v2/v3) and [Transport Layer Security] (TLS v1) [protocols] as well as a full-strength general purpose [cryptography] [Software library] for managing [Certificates], [Certificate Formats] and [Certificate Keystores]. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the [{$pagename}] toolkit and its related documentation.[1]

We have collected some useful [OpenSSL Commands].

!! [{$pagename}] and [TLS 1.3]
[{$pagename}] 1.1.1 release will include support for [TLSv1.3]. The new release will be binary and [API] compatible with [{$pagename}]  1.1.0. In __theory__, if your application supports [{$pagename}]  1.1.0, then all you need to do to upgrade is to drop in the new version of [{$pagename}]  when it becomes available and you will automatically start being able to use [TLSv1.3]. 

[{$pagename}] 1.1.1 will not be released until (at least) [TLS 1.3] is finalized.
