wuyou-sdk-go

A simple SDK for Fabric(v2.2.0), contains a gateway of Fabric and some cryptography tools.

gateway of Fabric(v2.2.0):

• work with configuration easily
• connect to Fabric easily
• invoke a chaincode easily

cryptography tools:

• SM2: key generation, encrypt/decrypt, sign/verify (like RSA)
• SM3: calculate digest of a message (like SHA256)
• SM4: key generation, encrypt/decrypt (like AES)
• Paillier: key generation, AddCiphertext/SubCiphertext, AddPlaintext/MulPlaintext/DivPlaintext

config

How to config crypto files (if you have org4, see the example below):

• copy "ordererOrganizations" and "peerOrganizations" of Fabric network
• paste "ordererOrganizations" and "peerOrganizations" to "crypto" in this project
• check files in "ordererOrganizations/example.com", there should be
  • "/msp/tlscacerts/tlsca.example.com-cert.pem"
  • "/users/User1@org4.example.com/msp/keystore/key.pem" (rename it to key.pem)
  • "/users/User1@org4.example.com/msp/signcerts/cert.pem" (rename it to cert.pem)
• check files in "peerOrganizations/org4.example.com", there should be
  • "/tlsca/tlsca.org4.example.com-cert.pem"
  • "/users/Admin@example.com/msp/keystore/key.pem" (rename it to key.pem)
  • "/users/Admin@example.com/msp/signcerts/cert.pem" (rename it to cert.pem)
• delete unused files in "ordererOrganizations" and "peerOrganizations"

How to config project yaml (if you have org4):

• open config.yaml in this project
• pay attention to "Org4"
• modify the values if necessary
