Unexpected first byte of WIF error for privateKey #170

Closed arycloud closed 2 years ago

arycloud commented 4 years ago

I'm using BitPay testnet wallet on mac and. I have exported the private key as a json file and then I copied all of its content paste in this tool to get WIF key and when I put the xPrivKey into my key.txt file which is mentioned in conf.ini I got another error as:

pycoin.encoding.EncodingError: unexpected first byte of WIF xprv9s21ZrQH143K31uJMPo9x8bWpuj9HS6cSAkJ67CDyzcB5LKwLMswKJECJz8LgpiAwzWjjY6p1943A9GYA12J2uPgBsXgqYHTqLS72e1pimr

What it looks like you have there is a bip39 extended private key. You need a private key for a single public key / address. You can learn more about BIP39 here https://iancoleman.io/bip39/

I'm new to the blockchain so don't min my basic questions, please! I'm using the BitPay app on mac for my bitcoin testnet wallet and when I exported my key from that app and decrypted it using this tool, I got the above mentioned private key. Here's what I got when exported from BitPay:

So, how can I get a valid private key from this JSON?

I don't know. We have instructions for getting a bitcoin testnet key here: https://github.com/blockchain-certificates/cert-issuer#create-a-bitcoin-issuing-address

arycloud commented 4 years ago

@AnthonyRonning this wallet is not working even, I have generated a wallet using the link mentioned on docs but I'm not able to transfer funds to that address.

ghost commented 4 years ago

Haven't used that one in awhile, looks like it's only doing mainnet now. Try this one https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html?design=alt-testnet#

Hi @arycloud

Befor we start : For "safety" ! it's recommended to run these sites OFFLINE by downloading them and running them locally : https://github.com/iancoleman/bip39

You have the xPrivKey and the mnemonic... Both of them can be used on https://iancoleman.io/bip39/ with a derivation path listed in the Json you decrypted then click on the BIP44 tab to generate a list of your addresses/private keys .Or, you can simply restore the seed mnemonic into any BIP44 compatible wallet :)

steps :

  1. Put your mnemonic in https://iancoleman.io/bip39/ (OFFLINE)
  2. choose Coin type (ex : BTCtestnet)
  3. choose Derivation Path BIP44
  4. edit to match your rootPath (rootPath listed in the json file ex : m/44'/1'/0')
  5. Et voila your Derived Addresses are bellow search for the exact one you interested in , and use the Private Key with the issuer 🥇

Hope the process is clear .

@AnthonyRonning it works on the testnet 👍
