During the SSL handshake "Client Hello" phase handled by "ssl_certificate_by_lua" the client sends the following data:
  • random
  • session_id
  • cipher_suites
  • compression_methods
  • extensions
Is it possible to access this  information?

Figured I'd toss this here since there's no other chatter on this thread. Yesterday a few patches were push upstream that added some relevant variables:

Doesn't quite cover everything here, but it's relevant-ish ;)
