hyperledger fabric .what are the uses of all the different certificates generated by cryptogen

Question

i have started working on hyperledger fabric. but I unable to figure out what are the uses of all different certificates generated by cryptogen thanks for the help

Answer 1

As per my understanding, each Organization requires a unique root certificate (ca-cert), that combine specific components peers and orderers to that organization. Transactions within Fabric are signed by an entity's private key which is keystore, and then checked/verified by means of a public key which is signcerts.

Different organizations also required to communicate their ledger so there is a need for CA or MSP on an organization level. Within each organization, we can have multiple peers so we need certification for these peers also. Even peers from different organizations can join each other using signcerts and TLScerts where signcerts for authentication and TLScerts for a secure handshake.
