What is Secure Sockets Layer (SSL) Encryption?
Secure Sockets Layer Encryption was originally developed by Netscape and uses two keys to encrypt data, a public key that is known to all and a private key that is provided only to the recipient. The public key is provided within a digital certificate and this also provides information to allow for the confirmation of the web server.
When a website is accessed that uses SSL (Secure Sockets Layer) the Internet browser will confirm it by providing a padlock icon in the far left side of the Internet address bar. If this padlock is clicked then information including the Certificate is provided, including the Certification Authority and the dates that the certificate is valid from and to.
When an issue is detected by the Internet browser of the SSL certificate on a website then the browser will block access to that site and provide a notice stating that the issue was detected. The user can then select to continue to the site if they want to.
An issue with the SSL certification could be that the certificate has expired, has been revoked or does not match the name of the site.
What is Transport Layer Security (TLS) Encryption?
Transport Layer Security (TLS) encryption is also referred to as SSL 3.0 and is widely used to encrypt communication between servers and web applications, including when Internet browsers are downloading a website. TLS is also used in the encryption of other communication including email and VOIP.
Transport Layer Security (TLS) is an extension of SSL, however, it was referred to as TLS to remove association with being developed by Netscape. TLS was proposed by the (IETF) Internet Engineering Task Force and first published in 1999. The most recent version was released in 2018 and identified as TLS 1.3.
