Understanding Various Certificates in Hyperledger fabric

Question

Hello I am tryin to use hyperledger fabric for a block chain implementation. I did the first-network demo and found lot of certificates in it. I have tried arranging them hierar

Answer 1

When you generate certificates of an org using cryptogen, you will see

├── ca
├── msp
├── peers
├── tlsca
└── users

Let me explain one by one CA: contains CA certificate & private key tlsca contains CA certificate & private key(TLS Version) MSP: This is organization MSP we need this to generate genesis block

Organizations:
    - &nbd
        Name: nbd
        ID: nbdMSP
        MSPDir: crypto-config/peerOrganizations/nbd/msp
        AnchorPeers:
            - Host: nbd-peer1-nbd
              Port: 7051

Peers: Peers contains two directories

├── msp
└── tls

Checking MSP of peer...

├── admincerts
├── cacerts
├── keystore
├── signcerts
└── tlscacerts

admincerts: This is peer msp, which is different to organization MSP, Every peer can have admin certs which is used to allow admin privilage user to issue admin level transactions cacerts: Trusted root CA cert keystore: Private key of the peer signcerts: signcert of peer cert tlscacerts:Trusted root CA cert (TLS Version)
