Network Security

As a long time mobile and server side engineer I have been involved in many different types of projects over the years.  Some small, and some large, but all with one recurring trend; the mobile clients need to consume data from a server to perform a task.  Sometimes this data being consumed is small, and other times the application needs to continuously poll or be notified of new data to keep the application up to date it real time. So far, this is probably nothing out of the ordinary, right?

OpenSSL 1.1.1 LTS
Featured Post

On September 11th, 2018 the OpenSSL team released a Long Term Support (LTS) version (1.1.1) of OpenSSL which will be supported by the community and the core team for the next five years.  This LTS release includes many new features such as TLS 1.3, ABI version compatibility, new cryptography algorithms, and an overhaul in many areas to the random number generators included in OpenSSL.

Python just received a minor version update to Python 3.7 with many new performance enhancements, added features, and module improvements to the language.   One of the existing Python modules in 3.7 that received some nice new enhancements is the ssl module. The updated ssl module now has enhanced hostname support, updates to how blacklisting and whitelisting work, but most importantly, conditional support for TLS 1.3 connections.
