It provides basic instructions for getting started interacting with a TLS-enabled network. It explains how to use TLS certificates and provide them in Fabric Java SDK API requests so that clients can send requests over a secured layer. The same approach is follow by the Fabric network as well. Fabric CA generates the identity or artifacts file for each of the node that can be the part of the cluster but for generating these artifacts files we also need to specify some property . Well these properties can be specified in crypto-config.yaml file.
