Hi in Chrome 56.0.2906.0 (Android) i found in the ssl client hello some unknown id's and extensions.
curve.id 43690cipherSuite: 14906exttension.Type 35466extension.type 51914
Does anyone can tell me what the meaning behind them are ?
These are related to GREASE for TLS implementation in Chrome ( 648327 - GREASE for TLS - chromium ).
OK with other words these are dummy suites that blow up the protocol with the intention that the server should ignore them.
Only to find out server that do not correctly ignore unknown suites/curves or extensions. From my point of view this is nothing that should be implemented in an client. This should be only part of test suites like in ssllabs.
