What is SSL/TLS and HTTPS?
We sometimes say "SSL/TLS". HTTPS is HTTP-within-SSL/TLS . SSL (TLS) establishes asecured, bidirectional tunnel for arbitrary binary data between two hosts. HTTP is a protocol for sending requests and receiving answers, each request and answer consisting of detailed headers and (possibly) some content.
Does TLS require a certificate?
Yes, most websites that conduct business on the internet require a digital TLS/SSL certificate to encrypt and secure private data that is transmitted. TLS/SSL certificates protect your business’ and your customers private information. In addition, without a certificate most major browsers will display a “Not Secure” message in the address bar.

What is the difference between TLS and SSL?
First of all, let’s get the easy one out of the way — what’s the difference between SSL and TLS? Here are the three things you need to know about TLS vs. SSL: 1 SSL and TLS do the same thing. They’re both protocols for encrypting (securing) information that’s traveling over a computer network. For example, encrypting credit card details while they’re in transit from a shopper to Amazon.com. 2 TLS is the new SSL. Technically speaking, SSL is the older protocol and is actually deprecated. TLS is the newer protocol that all up-to-date websites and software use. 3 Lingo is slow to change in this industry. Terms like “SSL certificates” are still widely used, even though what we refer to as SSL certificates are technically using the TLS protocol. But in common speech, lots of people still say SSL. We’re not going to get picky — you can say SSL or TLS and we’ll know what you mean!
How Is TLS Used Outside of HTTPS?
HTTPS is, by far, the most common way that TLS is used in the real world… but there are other implementations of TLS in use as well. For example, FTPS uses TLS to securely upload and download files from web servers for editing and management.
