is client certificate verify supported?

[chnex]

I was using the following code to add server certificate to http_listener, also tried to verify the certificate of external clients who are trying to connect to http_listener. The server certificate (line 5,6) works well, but as long as I add line 7, ssl handshake will fail, i.e. at client side, I could see --> ClientHello, <-- ServerHello/Certificate/CertificateRequest, --> Certificate/ClientKeyExchange/CertificateVerify, then no response from the server, and TLS 1.2 Handshake Finished, with this error: 140279477085840:error:140790E5:SSL routines:ssl23_write:ssl handshake failure:s23_lib.c:177. Is this a known issue? Thanks.

1. http_listener_config conf;
2. conf.set_ssl_context_callback(
3. [this](boost::asio::ssl::context &ctx) {
4. ctx.set_options(boost::asio::ssl::context::default_workarounds);
5. ctx.use_certificate_chain_file(this->CertPath);
6. ctx.use_private_key_file(this->PkPath, boost::asio::ssl::context::pem);
7. ctx.set_verify_mode(boost::asio::ssl::verify_peer | boost::asio::ssl::verify_fail_if_no_peer_cert);
8. ctx.set_verify_callback(boost::bind(verifyCertCallback,_1,_2);
9. });

Hi Chnex,

I am also struck at same point, getting "Error in SSL handshake". Is it solved or else any workaround for client certificate validation ..?

If anyone aware of this please comment ..!

hi venkata3903 you can by pass by error with snippet code. http_client_config config; config.set_validate_certificates(false); http_client client(ip, config);

Hi levuphuong,

Thanks for the info.

I did the same in client side, but i want to validate client certificate from server. So i have used the following code on server

http_listener_config server_config; server_config.set_ssl_context_callback([&](boost::asio::ssl::context& ctx) { ctx.set_verify_mode(boost::asio::ssl::verify_peer | boost::asio::ssl::verify_fail_if_no_peer_cert); }

even i use config.set_validate_certificates(false) on client , by adding above ctx.set_verify_mode in server , getting "Error in SSL handshake".

Thanks, Venkata3903
