Both Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are protocols that enable authenticated and encrypted communication between machines on a network. Despite the fact that the SSL protocol has been rendered obsolete with the advent of TLS 1.0 in 1999, it is common practise to refer to these interrelated technologies as “SSL” or “SSL/TLS.” TLS 1.3, the most current release, is defined in RFC 8446. (August 2018).
Both Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are protocols that enable authenticated and encrypted communication between machines on a network. Common parlance still uses the “SSL” and “SSL/TLS” moniker for these interrelated technologies, despite the fact that the SSL protocol has been deprecated since the debut of TLS 1.0 in 1999. Now what is SSL?
What exactly is an SSL certificate, and how do I get one?
what is SSL certificate ? It is a digital document that links a website’s identification to a cryptographic key pair, or public key and private key. Transport Layer Security certificates, or SSL/TLS certificates, are another name for SSL certificates. If the certificate includes a public key, the browser may use it to establish an encrypted TLS or HTTPS connection with the server. The certificate contains the necessary key. When digitally signing documents or web pages, the private key is utilised and is kept securely on the server (such as images and JavaScript files).
- SSL certificates also include identifying information, such as a website’s domain name and, if provided, the website owner’s details. An SSL certificate contains these data. If the web server’s SSL certificate was signed by a publicly recognised and renowned CA, like SSL.com, then browsers and operating systems will trust the digitally signed content as being real and valid. A secure sockets layer (SSL) certificate is a kind of X.509 certificate.
- In 1999, the SSL (Secure Sockets Layer) protocol was superseded by the TLS (Transport Layer Security) standard for authentication and encryption. “Transport Layer Security” (or “TLS”) is an abbreviation. The specification for TLS 1.3 may be found in RFC 8446. (August 2018).
Does a static IP address have to be used with SSL/TLS?
There was a time when each SSL certificate put on a web server required its own unique IP address. This is no longer the case, thanks to a technological advancement known as Server Name Indication (SNI). To ensure optimal operation, your hosting platform must support SNI.

What is the best port to use with SSL/TLS, and why is it recommended?
Port 443 is the de facto standard for SSL/TLS connections, and it provides the greatest possible degree of compatibility. Nevertheless, any available port may be used.
What is the most recent version of SSL/TLS?
TLS 1.3, established by RFC 8446 in August 2018, is the most recent SSL/TLS version available. The TLS 1.2 standard (RFC 5246) was created in August 2008 and is still widely used today. SSL/TLS versions previous to TLS 1.2 are no longer considered secure and should no longer be used.
