Qualys SSL Labs maintains great tools for checking that TLS has been set up correctly. This project scrapes their User Agent Capabilities pages --- sorry Qualys --- and turns it into open data.
Qualys has collected data on 36 clients (e.g. Chrome, Android, OpenSSL) including:
- TLS versions supported (SSL 2, SSL 3, TLS 1.0, TLS 1.1, TLS 1.2).
- Ciphers supported (in preference order and using IANA names), and information on whether ciphers support forward secrecy or are weak or insecure.
- Other protocol details (e.g. support for Server Name Indication (SNI)).
You'll find this scraped and stored in this repository as clients.json and clients.csv, with additional cipher information in ciphers.json.
I've also copied Mozilla's cipher name correspondence table into cipher_names.csv.
