How is the SSL protocol used

SSL - Secure Socket Layer

SSL is a protocol used to authenticate and encrypt Internet connections. SSL is the standard protocol or the extension for application protocols that do not include encryption for secure connections. SSL intervenes between the application and transport protocols. A typical example of the use of SSL is the secure retrieval of confidential data via HTTP and the secure transmission of confidential data to the HTTP server. As a rule, the aim is to guarantee the authenticity of the server contacted by means of a certificate and to encrypt the connection between client and server.

Note: The original SSL is now obsolete and has been incorporated into TLS. Although TLS is generally used today, it is still called SSL. For historical reasons, software products and libraries sometimes have "SSL" in their names, even though they are capable of TLS.

SSL or TLS?

SSL was originally developed by Netscape in the 1990s for the "Netscape Navigator" browser and has long been "the standard" for encrypting Internet connections. The further development of SSL was ended with version 3. The IETF has adopted SSL 3.0, made a few changes and specified it as a new standard that is incompatible with SSL with the designation TLS (SSL version 3.1).
In many cases, functions in software and libraries still have the designation SSL in their names, even though they use TLS. That is why it is still common today to speak of SSL, even though one actually means the technical implementation of TLS.
In practice, however, it is completely irrelevant whether you say SSL or TLS.
