TLS Versions
Versions
TLS has three places for versions in the Client Hello:
- Record version
- Handshake version
- supported_versions extension (in TLS 1.3)
Max TLS versions
This table lists the maximum supported version of connections, either from the Handshake version, or the first (non-GREASE) listed in the supported_versions extension.
