<meta itemprop="description" content="Support gRPC SSL transportation for OAP server For OAP communication we are currently using gRPC, a multi-platform RPC framework that uses protocol buffers for message serialization. The nice part about gRPC is that it promotes the use of SSL/TLS to authenticate and encrypt exchanges. Now OAP supports to enable SSL transportation for gRPC receivers.
You can follow below steps to enable this feature
Creating SSL/TLS Certificates It seems like step one is to generate certificates and key files for encrypting communication.">
