An SSL certificate also includes identifying information about a website, including its domain name and, optionally, identifying information about the site’s owner. If the web server’s SSL certificate is signed by a publicly trusted certificate authority (CA), like REGXA.COM, digitally signed content from the server will be trusted by end users’ web browsers and operating systems as authentic.
TLS (Transport Layer Security), released in 1999, is the successor to the SSL (Secure Sockets Layer) protocol for authentication and encryption. TLS 1.3 is defined in in RFC 8446 (August 2018).
At one time it was a mandatory requirement to have a dedicated IP for each SSL certificate on a web server. This is no longer the case due to a technology called Server Name Indication (SNI). Your hosting platform will specifically have to support SNI.
For maximum compatibility, port
443 is the standard, thus recommended, port used for secured SSL/TLS communications. However, any port can be used.
TLS 1.3, defined in August 2018 by RFC 8446, is the most recent version of SSL/TLS. TLS 1.2 (RFC 5246) was defined in August 2018 and also remains in wide use. Versions of SSL/TLS prior to TLS 1.2 are considered insecure and should no longer be used.
