In general we would say  SSL Certificates protect your sensitive information such as credit card information, usernames, passwords etc. This particular kind of cryptography harnesses the power of two keys which are long strings of randomly generated numbers. One is called a private key and another one is called a public key.A public key is known to your server and available in the public domain. It can be used to encrypt any message. In this post I will show you how to properly configure OpenSSL which  is full-featured toolkit for the Transport Layer Security (...
