Re: #fabric-ca #fabric-ca

Thank for the prompt reply, we are trying to use a fabric samples that has mutual TLS enabled with HLExplorer as a client, but looks like fabric doesn't provide one, will have to modify the balance transfer client in order to use mutual TLS.

Another question is, how to generate the client key, and cert., and both key, cert needs to be on fabric-ca server registered?  it is not clear, and what type of tools we can use to generate both.

Hi Nick,

The error message clearly says that the server (peer) did not receive the correct client certificate.
I assume along with CORE_PEER_TLS_CLIENTAUTHREQUIRED = true, you have set below env variables correctly
  • CORE_PEER_TLS_CLIENTCERT_FILE = client certificate
You may use the fabric-ca to generate these client certificates. If you wish to use Openssl to generate client certs, keep in mind RSA keys are not supported by fabric.

You have to assign these certificates to client instance as well. I prefer to do it this way. 

I would have used curl to verify 2way tls authentication configuration, if it was https.
curl -v --cacert ./ca.crt --key ./client.key --cert ./client.crt

Furthermore, you may check out this blog, could be of some help.

Kind regards

Are there any fabric samples with Mutual TLS enabled, aka. CORE_PEER_TLS_CLIENTAUTHREQUIRED=true ?
I enabled balance transfer with Mutual TLS, but it fails when running with error:
