How to get the client certificate or more precisely the client DN in GRPC++?

Question

I have clearly understood how to establish a two-way authenticated SSL communication in GRPC++,but now I desire to obtain the way to get SSL client DN in the established TLS communication to make a further identity status classification. Thanks if you have some suggestions.

Answer 1

You can get the peer certificate chain from gRPC AuthContext, under the property name (GRPC_X509_PEM_CERT_CHAIN_PROPERTY_NAME).
