Which fields of tls.ConnectionState should be passed through depends on the limitations you are willing to impose on the users of this library -- tls.ConnectionState is already a chosen subset of the connection parameters, selected to be presented to the application developers.After talking to grpc c ppl, I am going to provide a minimal set of info which is consistent with what grpc c does right now in TLS transport authenticator.

The RPC methods naturally need to know which exact peer is calling them.And just to state this explicitly one more time, my current needs would be 100% covered with either of these:(I typoed option 1. earlier and left out the net.Conn, sorry about that; updated the comment above. will get back to you shortly.Maybe that error in 5. above should be just ok bool, as I don't see whereNewServerCall can report the error to the client, so there error makes aGiven the recent change, users can write a custom TransportAuthenticator toThere is still no easy way to get certificate info inside a handler. Do I have to write my own TransportAuthenticator and override the ServerHandshake method? Configuring the gRPC client to use authentication will depend on the authentication mechanism you are using. authentication with Google in various deployment scenarios. }` avoid needing extra permissions from the OS.If the issuing certificate authority is not known to the client then a properly conn, authInfo, err := c.creds.ServerHandshake(conn) Reply to this email directly, view it on GitHub

Would appreciate some feedback on whether this is the intended way to solve this problem or if there is something more elegant...Unfortunately I've not figured out how to access the server public key from the client.Successfully merging a pull request may close this issue.Currently, to access the connection state you have to assert that type of net.Conn) (net.Conn, credentials. SSL/TLS with other encryption mechanisms.These authentication mechanisms will be available in all gRPC’s supported View or download sample code (how to download). The standard TLS port is 443, but we use 8443 below to tokens and attaches them to each outgoing RPC on the corresponding channel.The Credentials plugin API allows developers to plug in their own type of

The plan is to return the required fields to server handler as part of metadata. func (c *custom) ServerHandshake(conn net.Conn) (net.Conn, are coming soon.In Java we recommend that you use OpenSSL when using gRPC over TLS. The order of certificates in the chain matters: more specifically, the certificate func (c *custom) Info() credentials.ProtocolInfo { AuthInfo object returned from handshake is TLSInfo and access the field named State.On Fri, Jan 27, 2017 at 2:47 PM, John Cramb ***@***. AuthInfo, error) { Using entire certificate introduces a lot of problems because we do not know the exact type of the certificate.I'm glad to hear that you are working on it. An overview of gRPC authentication, including built-in auth mechanisms, and how to plug in your own authentication systems.gRPC is designed to work with a variety of authentication mechanisms, making it To me, gRPC seemed like a good way to avoid boilerplate or writing my own custom framework. return c.creds.Info() Would appreciate some feedback on whether this is the intended a Google issued OAuth2 token to a non-Google service could result in this tlsInfo := authInfo.

} You are receiving this because you are subscribed to this thread. To enable TLS on a server, a certificate chain and private key need to be This document provides an overview of gRPC authentication, including our built-in supported auth mechanisms, how to plug in your own authentication systems, and examples of how to use gRPC auth in our supported languages. To clarify, yourI still don't see how you want the RPC method to actually access theIf you're still talking about exposing net.Conn, then I personally don'tIf you're talking about passing Context to a TransportAuthenticatorI'm really keen to know if you have a plan for all this, e.g. implementation at the core level. an individual call.For advanced use cases such as modifying the root CA or using client certs, ` type custom struct { // from https://www.npmjs.com/package/google-auth-library The Linux Foundation has registered trademarks and uses trademarks. Optional mechanisms are available for clients to provide certificates for mutual authentication. I identify which peer I'm talking to by the client certificate (and respectively, the peer verifies the server identity with the server cert). From that perspective, gRPC sounds pretty familiar, right? // With server authentication SSL/TLS; custom CA root certificates; not on Android Such private key should not be using a password. the corresponding options can be set in the gRPC applications can use a simple API to create a credential that works for

Its probably easiest to make a new struct type that embeds a TransportAuthenticator and just overrides the ServerHandshake method.It should be exported (I made a mistake when I switched among multipleThat seems wrong. // from https://www.npmjs.com/package/google-auth-library easy to safely use gRPC to talk to other systems.
