Open Source Secure Paper Wallet Generator

Open Source Secure Paper Wallet Generator

Runs https://GeneratePaperWallet.com

It uses random data from your mouse mixed with entropy from your OS to generate paper wallets.

The paper wallets provide a private key, a receiving address, and wallet words.

Wallet words are a mnemonic that represents the private key and can always be used to recover the private key.

Wallet words follow the BIP39 standard, and where available BIP44 BIP32 derivation paths are used to arrive at the private key, so they work in common wallets such as Electrum as well.

• BIP32 (https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki)
• BIP39 (https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki)
• BIP44 (https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki)

These paper wallets can then be printed off, or written down on paper for safe keeping.

GeneratePaperWallet.com should also work locally through 'Save Page'. Note that the code here may be in the process of development, so it is best to stick to the site.

Installation

Install libraries mentioned above with

npm install -library-name-

Then concat worker and worker-coin specific js files.

Then run browserify, npx babel and npx uglify.
