nkn-wallet

A next generation NKN wallet with built-in age encryption and NKN OpenAPI support.

nkn-wallet is a library that implements nkn-sdk-go with a new wallet functionality utilizing age encryption and using the NKN OpenAPI for querying the NKN blockchain.

Upcoming releases will include the possibility for encryption by SSH public key ("ssh-ed25519 AAAA...", "ssh-rsa AAAA...") stored on disk or by fetching the keys from a Github user profile (github.com/[user].keys).

While nkn-wallet has its own wallet implementation the underlying SDK functionality remains the same and is compatible with nkn-sdk-go. The move to age as an encryption toolkit results in overall less loc since there is no need to implement scrypt functionality manually. This wallet implementation uses age's internal scrypt feature which is identical to the original NKN wallet implementation performance-wise and slightly enhanced security-wise through the use of an additional layer, that is, the derived scrypt key being encrypted again with a ChaCha20-Poly1305 AEAD.

Features:

Manage all your different accounts from a central place
State-of-the-art encryption with Age
Manage multiple accounts in a single wallet file (multiwallet capability)
List all your accounts
Set an alias for your account
Show the balance of your account
Show transactions of your account
Move funds between accounts in the wallet
Transfer funds to another NKN address
Restore your accounts
Change password of your account
Change or set an alias for your account
NKN OpenAPI support

Library

Installation

import nknwallet "github.com/omani/nkn-wallet"

Example

package main

import (
	"fmt"
	"log"

	"github.com/nknorg/nkn-sdk-go"
	nknwallet "github.com/omani/nkn-wallet"
)

func main() {
	passwd := []byte("secretpassword")
	store := nknwallet.NewStore("mywallet.json")

	walletcfg := &nkn.WalletConfig{}
	wallet, err := store.NewWallet(passwd, "my-new-shiny-account", walletcfg)
	if err != nil {
		log.Fatal(err)
	}

	// save new wallet to store (otherwise it is in-memory only)
	store.SaveWallet(wallet)

	// list wallets in store
	store.ListWallets()

	// get balance of newly created account
	balance, err := wallet.OpenAPI().GetBalance()
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Address: %s - Balance: %s NKN\n", wallet.Address(), balance)

	// fetch a wallet from store
	wallet, err = store.GetWalletByAlias("my-new-shiny-account", passwd)
	if err != nil {
		log.Fatal(err)
	}

	// print account address
	fmt.Printf("Address of account: %s\n", wallet.Address())

	// get transactions associated with account
	txn, err := wallet.OpenAPI().GetTransactions()
	if err != nil {
		log.Fatal(err)
	}
	if len(txn.Data) == 0 {
		fmt.Println("Account has no transactions.")
		return
	}

	for _, tx := range txn.Data {
		fmt.Printf("Sent %s NKN to address %s", tx.Payload.Amount, tx.Payload.RecipientWallet)
	}
}

Use with nkn-sdk-go

package main

import (
	"crypto/rand"
	"encoding/hex"
	"fmt"
	"log"
	"time"

	"github.com/nknorg/nkn-sdk-go"
	nknwallet "github.com/omani/nkn-wallet"
)

func main() {
	store := nknwallet.NewStore("mywallet.json")

	walletcfg := &nkn.WalletConfig{}
	wallet, err := store.NewWallet([]byte("secretpassword"), "my-new-shiny-account", walletcfg)
	if err != nil {
		log.Fatal(err)
	}

	// continue to use nkn-sdk-go as usual
	err = func() error {
		// get the underlying nkn.Account
		account := wallet.Account()

		fromIdentifier := make([]byte, 8)
		_, err = rand.Read(fromIdentifier)
		if err != nil {
			return err
		}
		toIdentifier := make([]byte, 8)
		_, err = rand.Read(toIdentifier)
		if err != nil {
			return err
		}

		fromClient, err := nkn.NewMultiClient(account, hex.EncodeToString(fromIdentifier), 4, false, nil)
		if err != nil {
			return err
		}
		defer fromClient.Close()
		<-fromClient.OnConnect.C

		toClient, err := nkn.NewMultiClient(account, hex.EncodeToString(toIdentifier), 4, false, nil)
		if err != nil {
			return err
		}
		defer toClient.Close()
		<-toClient.OnConnect.C

		time.Sleep(time.Second)

		timeSent := time.Now().UnixNano() / int64(time.Millisecond)
		var timeReceived int64
		go func() {
			msg := <-toClient.OnMessage.C
			timeReceived = time.Now().UnixNano() / int64(time.Millisecond)
			isEncryptedStr := "unencrypted"
			if msg.Encrypted {
				isEncryptedStr = "encrypted"
			}
			log.Println("Receive", isEncryptedStr, "message", "\""+string(msg.Data)+"\"", "from", msg.Src, "after", timeReceived-timeSent, "ms")
			// []byte("World") can be replaced with "World" for text payload type
			msg.Reply([]byte("World"))
		}()

		log.Println("Send message from", fromClient.Address(), "to", toClient.Address())
		// []byte("Hello") can be replaced with "Hello" for text payload type
		onReply, err := fromClient.Send(nkn.NewStringArray(toClient.Address()), []byte("Hello"), nil)
		if err != nil {
			return err
		}
		reply := <-onReply.C
		isEncryptedStr := "unencrypted"
		if reply.Encrypted {
			isEncryptedStr = "encrypted"
		}
		timeResponse := time.Now().UnixNano() / int64(time.Millisecond)
		log.Println("Got", isEncryptedStr, "reply", "\""+string(reply.Data)+"\"", "from", reply.Src, "after", timeResponse-timeReceived, "ms")

		// wait to send receipt
		time.Sleep(time.Second)

		return nil
	}()
	if err != nil {
		fmt.Println(err)
	}

}

Example with age encryption

Install age

Refer to https://github.com/FiloSottile/age to see how to install age.

Create a new age identity

~ $ cd /tmp/
/tmp $ age-keygen > ident1
age-keygen: warning: writing secret key to a world-readable file
Public key: age1f2fcrl2l5swmd4nquukwhh7kd8qz579usp74ee4t7gm068wqpgjqwnuldf

Create another one for demonstration purposes

/tmp $ age-keygen > ident2
age-keygen: warning: writing secret key to a world-readable file
Public key: age1pklphvwtf6sfedu4seth44vepy597tesc4e82zsh536lj58ggp4szg25p3

Use newly created age identity as a recipient for new wallet

The age encryption is stored as an armor in the armor field. the associated NKN address, id and alias are cleartext.

The base64 decoded armor looks like this:
