<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Had a question about obtaining client ciphers from OpenSSL library.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">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).</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Is there any other way we can read the client ciphersuite or the client-server negotiated ciphersuite in the callback we register to SSL_CTX_set_tlsext_servername_callback?</span><o:p></o:p></p>
