About OpenSSL OpenSSL
SSL is an abbreviation for the Secure Socket Layer protocol, which provides covert transmission over the Internet. Netscape Company introduced the SSL protocol standard at the same time as the first web browser, there are now 3.0 versions. SSL employs public key technology. The goal is to ensure the confidentiality and reliability of communication between two applications, enabling sim
