Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

import Web3 from 'web3'

function getCallback(payload, cb) {
  return function(err, result) {
    const obj = {}
    const keys = ['id', 'jsonrpc']
    keys.forEach(key => {
      obj[key] = payload[key]
    })
    obj.result = result

// web3 contract
var web3Contract = new web3.eth.Contract(abi, address);

// dagger contract
var contract = dagger.contract(web3Contract);
var filter = contract.events.Transfer({filter: {from: '0x123456...'}, room: 'latest'});
// watch
filter.watch(function(data, removed){
    // data.returnValues.to : address to which it has been transferred to
    // data.returnValues.value : value which has been transferred
