Hyperledger Fabric Java SDK Use GRPCS for peer and orderer connections - ssl

Question

I have a Spring Boot project using the fabric-java-sdk pointing to the BYFN network that I've stood up locally.
The BYFN network does not have a CA container.
I am trying to connect to the peer and orderer with grpcs since tls is enabled on my local BYFN network. Grpc fails.
However, it appears that it doesn't like the CN or some other field in the cert presented by the peer during the initial TLS handshake. I think it doesn't like that I am pointing to localhost for the grpcs url, but the CN is not 'localhost' in the cert presented by the peer, nor are there any 'localhost' SANs. (This based on my weak understanding of TLS).
Am I missing something built into the Fabric Java SDK to get this to work? Or maybe I need to add some config to the peer and orderer nodes so that their tls certs have 'localhost' SANs?
Code and trace below, thank you.
private static void initHfClient() throws Exception {
hfClient = HFClient.createNewInstance();
CryptoSuite cs = CryptoSuite.Factory.getCryptoSuite();
hfClient.setCryptoSuite(cs);
User context = new LocalUser();
hfClient.setUserContext(context);
Channel channel = hfClient.newChannel("mychannel");
Peer p = hfClient.newPeer("peer0.org1.example.com", "grpcs://localhost:7051");
channel.addPeer(p);
channel.addOrderer(hfClient.newOrderer("orderer.example.com", "grpcs://localhost:7050"));
channel.initialize();
}

Answer 1

I finally figured it out. Here's the high level for getting this to work:
The cryptogen tool from Fabric consumes a yaml file, for me in crypto-config.yaml. You can set SANs in there. So I added "localhost" as a SAN for all peers and orderers.
The JVM needs a custom truststore that accepts the certs that are going to be presented by the peer and orderer during grpcs tls handshake. Use the Java keytool to create a truststore with the .crt files in: crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls and crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls. Note that YMMV on the paths to the .crt files, and perhaps not all are required to be in the truststore to get it to work. I just threw all of them in there.
Pass the truststore to the JVM with -Djava.net.ssl.trustStore=truststore.jks -Djava.net.ssl.trustStorePassword=changeit, or in Spring like: System.setProperty("javax.net.ssl.trustStore", pathToTrustStore) System.setProperty("javax.net.ssl.trustStorePassword", pw)
Keytool create truststore instructions: https://docs.oracle.com/cd/E19509-01/820-3503/ggfka/index.html
(the aliases used when adding certs to the store don't appear to matter).
-- by request, here's an example of setting SANs in crypto-config.yaml:
