BYFN Root CA Certificates
Where are BYFN root CA (Certificate Authority) certificates are located?
Like all Hyperledger Fabric networks, BYFN is a private and permission based hyperledger network. Access to the network are control PKI (Public Key Infrastructure) technology.
In BYFN, each organization who manages peer nodes acts a root CA (Certificate Authority) to sign and issue X.509 certificates to control its peer nodes and systems/users who wants to interact with it peer nodes.
If your BYFN is obtained from the Hyperledger Fabric Binary Package at http://bit.ly/2ysbOFE, root CA certificates of all organizations are stored in the ./crypto-config sub-directory.
For example, the private key and the public key certificate of the first organization, org1.example.com, are stored in the ./crypto-config/peerOrganizations/org1.example.com/ca sub-directory.
$ cd ~/hyperledger-binaries/fabric-samples/first-network $ ls -l crypto-config/peerOrganizations/org1.example.com/ca -rw------- 1 fyicenter 241 Apr 1 02:00 ab90b589...3d0599d0_sk -rw-rw-r-- 1 fyicenter 863 Apr 1 02:00 ca.org1.example.com-cert.pem
The each root CA signs and issues its first certificate for the default administrator, Admin@org1.example.com, and stores it in
$ cd ~/hyperledger-binaries/fabric-samples/first-network $ more crypto-config/peerOrganizations/org1.example.com\ /peers/peer0.org1.example.com/msp/admincerts/Admin@org1.example.com-cert.pem -----BEGIN CERTIFICATE----- MIICKjCCAdCgAwIBAgIQJaIMpniwRgmBvyIdgOgrsTAKBggqhkjOPQQDAjBzMQsw .... bOtHwX2tLdc0msnvEKqFvSHNLQJM6jzav3BCJvG2 -----END CERTIFICATE-----
If you decode this certificate, you will see:
Subject: Common Name (CN): Admin@org1.example.com Organizational Unit Name (OU): client Locality Name (L): San Francisco State or Province Name (ST): California Country Name (C): US Issuer: Common Name (CN): ca.org1.example.com Organization Name (O): org1.example.com Locality Name (L): San Francisco State or Province Name (ST): California Country Name (C): US
