No no, they're not. They're names of specific protocols with specific capabilities and versions. "SSL 1.0" and "TLS 1.0" are very different. (see https://aws.amazon.com/compare/the-difference-between-ssl-an...)
The important bits:
- "SSL" is a set of protocols so ridiculously old, busted and insecure that nobody should ever use them. It's like talking about Sanskrit; ancient and dead.
- "TLS" is way better than "SSL", but still there are insecure versions. Any version before 1.2 is no longer supported due to security holes.
- Technically an "ssl certificate" is neither "SSL" nor "TLS", it's really an "X.509 Certificate with Extended Key Usage: Server Authentication". But that doesn't roll off the tongue. You could use a cert from 1996 in a modern TLS server; the problem would be its expiration date, and the hash/signature functions used back then are deprecated. (some servers still support insecure methods to support older clients, which is bad)
The point is more that SSL 3.0 and TLS 1.0 were nearly identical. That is, the breaks in similarity were at SSL 2.0 -> SSL 3.0 (and TLS 1.2 -> TLS 1.3, to a lesser extent), as opposed to the common misconception that TLS 1.0 is what changed everything.
But yes, it's all a bit irrelevant now that anything below TLS 1.2 is sketchy to use.
