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 by Internet servers, including the majority of HTTPS websites.
hope it will enough
OpenSSL is a software library for many applications, written in the C programming language that implements the SSL (secure sockets layer) and TLS (transport layer security) web security protocols.
SSL and TLS are methods for using cryptography to secure communication between two parties. Although there are some crucial differences at the technical level, they both work the same way. Hope it helps!
