instructions for use

Example

package main

import (
  "fmt"
  cb "github.com/cnc-project/cnc-bls"
)

func main(){
  // Generate a mnemonic for memorization or user-friendly seeds
  entropy, _ := cb.NewEntropy()
  mnemonic, _ := cb.NewMnemonic(entropy)

  // Generate a Bip32 HD wallet for the mnemonic and a user supplied password
  seed := cb.NewSeed(mnemonic, "Secret Passphrase")

  priKey := cb.KeyGen(seed)
  publicKey := priKey.GetPublicKey()

  // Display mnemonic and keys
  fmt.Println("Mnemonic: ", mnemonic)
  fmt.Println("Master private key: ", priKey)
  fmt.Println("Master public key: ", publicKey)
  fmt.Println("Master generate fingerprint", publicKey.FingerPrint())
}
