GRPC_TLS_OPTION_B='GRPC_SSL_REQUEST_CLIENT_CERTIFICATE_BUT_DONT_VERIFY'
# Server requests client certificate but does not enforce that the client presents a certificate.
# If the client presents a certificate, the client authentication is left to the application (the necessary metadata will be available to the application via authentication context properties, see grpc_auth_context).
# The client's key certificate pair must be valid for the SSL connection to be established.

GRPC_TLS_OPTION_C='GRPC_SSL_REQUEST_CLIENT_CERTIFICATE_AND_VERIFY'
# Server requests client certificate but does not enforce that the client presents a certificate.
# If the client presents a certificate, the client authentication is done by the gRPC framework. (For a successful connection the client needs to either present a certificate that can be verified against the root certificate configured by the server or not present a certificate at all)
# The client's key certificate pair must be valid for the SSL connection to be established.

GRPC_TLS_OPTION_D='GRPC_SSL_REQUEST_AND_REQUIRE_CLIENT_CERTIFICATE_BUT_DONT_VERIFY'
# Server requests client certificate and enforces that the client presents a certificate.
# If the client presents a certificate, the client authentication is left to the application (the necessary metadata will be available to the application via authentication context properties, see grpc_auth_context).
# The client's key certificate pair must be valid for the SSL connection to be established.
