[openssl-users] Question about fetching client ciphers

[Lodaya, Varun]

Hey Guys,

Had a question about obtaining client ciphers from OpenSSL library.
Currently we are doing SNI by registering to SSL_CTX_set_tlsext_servername_callback and taking a decision on the right certificate. We were trying to figure out how we can get more information like client ciphers, etc in that callback. I see the ‘SSL_get_client_ciphers’ API in newer (Openssl 1.1.0+), but not in the older versions (Openssl 1.0.2).

Is there any other way we can read the client ciphersuite in the callback we register to SSL_CTX_set_tlsext_servername_callback

Thanks,
Varun
