What is the difference between TLS and SSL?

TLS is an upgraded version of SSL and built upon previous versions. It started off with SSL 1.0 and till date, the current version stays at TLS 1.2. SSL has transitioned to TLS over the past two decades and been through several rounds of security enhancements, as well as a name change.

Read more on the transition phrase here.

TLS/SSL provides:

  • Encryption of communication contents to prevent divulging of information
  • Verification of communications ends to prevent spoofing
  • Verification to examine whether messages have been manipulated during transmission

Q: Why is everyone calling it SSL when TLS should be the right term to use?

A: Interestingly, when TLS was introduced in 1999, the difference between both protocols were so insignificant that everyone including Certificate Authorities (CAs) continue to use SSL. CAs did attempt to push out and use the word TLS (as you may have seen), however, there hasn’t been much of a success. It is fairly common to see TLS and SSL used interchangeably.

Q: Why was TLS introduced?

A: TLS was introduced because it was deemed as a more suitable term to use when describing communication privacy over the internet. How this protocol works is it creates multiple layers on top of one another. At each layer, messages may include fields for lengths, description and content. 

Q: Am I getting a TLS certificate if I purchase an SSL certificate? 

A: Yes. As mentioned, TLS/SSL is a protocol name and all CAs are under strict regulation by the CA/Browser Forum to provide a digital certificate that is compatible with the latest protocol (currently TLS 1.2). You would need to disable SSL 2.0 and SSL 3.0 in your servers to remove all known vulnerabilities associated with the older protocols.

Q: Will there be further updates on TLS/SSL?

A: Yes. The security community at large is looking at ways to improve this technology. As of January 2016, TLS 1.3 is at a working draft stage where it looks to remove weak signatures, remove support for obsolete cipher suites and upgrade the technology for TLS. 

Q: Will my old or existing TLS/SSL certificate be affected when there is an update?

A: When there is an update on the protocol, your relevant CAs would publish the information on their site. It is also the IT security administrator’s duty to regularly check for updates and configure the certificate accordingly to instructions provided by CAs.
