Error: Private key does not satisfy the curve requirements (ie. it is invalid)

[strawberry-code]

I followed step by step the instruction to import accounts private key using Metamask, but I get:

The strange thing is that in truffle framework I am able to use HDWalletProvider and string private key. Using it in my code doesn't work (nor truffle-hdwallet-provider nor truffle-hdwallet-provider-privkey).

Here is how I use it:

const MNEMONIC = 'PRIVATEKEYFROMMETAMASK';
const provider = new HDWalletProvider(MNEMONIC, "https://ropsten.infura.io/v3/INFURATOKEN");
const web3 = new Web3(provider);

Are you using web3 1.0.0 or the old web3? You need to use this package, truffle-hdwallet-provider-privkey to make the private key work instead of the mnemonic.

You might need to make the private keys an array, like:

const MNEMONIC =[ 'PRIVATEKEYFROMMETAMASK'];
const provider = new HDWalletProvider(MNEMONIC, "https://ropsten.infura.io/v3/INFURATOKEN");
const web3 = new Web3(provider);

If that works for you, let me know and I'll update the docs.

Hi @Cristiano-c, I had this same issue and found your issue.

Someone else answered this in: ethereumjs/ethereumjs-wallet#20 suggesting to use Buffer.from('<PRIVATE_KEY>', 'hex') to convert your private key to a Buffer first.

This should work for you:

const privateKey = Buffer.from('PRIVATEKEYFROMMETAMASK', 'hex');
const provider = new HDWalletProvider(privateKey, "https://ropsten.infura.io/v3/INFURATOKEN");
const web3 = new Web3(provider);

[piotr-roslaniec]

Notice that HDWalletProvider constructor takes in an array of private keys:

const HDWalletProvider = require("truffle-hdwallet-provider-privkey");
const privateKeys = ["myPrivateKey"]; 

module.exports = {
  networks: {
    rinkeby: {
      provider: function() {
        return new HDWalletProvider(
          privateKeys,
          "https://rinkeby.infura.io/v3/<myInfuraToken>"
        );
      },
      network_id: 4,
      gas: 4500000,
      gasPrice: 100000000
    }
  }
};

Are you wrapping the privateKey in an array? Make sure to do that let array = [privateKey]

[namelessperson0]

In this code base, the private key should not start with 0x. Remove 0x if present.

I have an old wallet inherited from family since 2016 which has been backup using keystore Json and password. i have been trying to recover the wallet using various wallet and they keep giving response "private key do not satisfy the curve requirements".

the only wallet that was able to import it is 'Math Wallet' on my android phone, but when i want to make transfer out, it request for password and when i input it i give a response "Privatekey error".

If i try to copy the private in order to export it .. it gives me back "Privatekey error".

please help
