One of the most critical universal components of all technology is the ability to collect, analyse and serve data. Software solutions from Games, IoT, Mobile Apps to Enterprise Solutions all have one common component; data storage, management and retrieval. When I first started learning to code before I knew this…

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. It is widely used in internet web servers, serving a majority of all websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols. The core library, written in C programming language, implements basic cryptographic functions and provides various utility functions. Wrappers allowing the use of the OpenSSL library in a variety of computer languages are available.
