There are no problems with the protocol; it has had extensive analysis. There are no known implementation bugs, but of course that doesn’t mean there are none. Most browsers will use TLS 1.3 if the server supports it. Many big websites
or providers use it. Go ahead. It does a smidgen more crypto work, but client/server latency is reduced. As for TLS 1.2, it has not had as much analysis, but has no known protocol flaws. It is also considered safe to use. Do not use TLS 1.1, TLS 1.0 or SSL 3. |
