getNewWalletFromSeed(): Entropy source not available

[sollerias]

Hello, guys! Could you, please, help me with this problem:
I couldn't process getNewWalletFromSeed() method, just get error: Entropy source not available.

OS: macOS Sierra 10.12.6
Node.js: 12.8.1

What does it mean? How to resolve this issue?

I enclose my code below:

const {
  getNewWalletFromSeed,
} = require('@lunie/cosmos-keys');

const createWallet = async () => {
  const mnemonic = "gentle mutual speak consider mandate kingdom cash explain soul exile cabin squeeze";

  try {
    const {
      cosmosAddress,
      privateKey,
      publicKey
    } = getNewWalletFromSeed(mnemonic);

  } catch (error) {
    console.log(error);
  }
};

Thanks a lot in advance!

I can reproduce this. It happens even without calling createWallet from the example. Here is the stacktrace:

I can offer to integrate the secp256k1 implementation from @cosmjs/crypto here, which is well tested in browser and node. It does not require randomness for signing. Please let me know if this is desired.

@sollerias have you solved it?

[faboweb]

The library works in the browser only. Checkout @cosmjs/launchpad for a more versatile library.

@faboweb could you add this to readme, so that it's obvious at the first glance on repo?
