2 Javascript Bitcoin tool

*** DO NOT USE THIS TOOL IN PRODUCTION. YOU WILL LOSE YOUR BITCOINS ***

This is the Brainwallet application. Some people have lost their Bitcoins to hackers when using the passphrase functionality to generate private keys for addresses. Hackers were able to steal their Bitcoins because of their chosen "weak" passphrase. Using passphrases to generate addresses is regarded unsafe! I have removed the address generator functionality.

Use this tool for educational pupose only.

The following functionalities are implemented in the tool:
  • Online converter, including Base58 decoder and encoder
  • Armory and Electrum deterministic wallets implementation
  • RFC 1751 JavaScript implementation
  • Bitcoin transactions editor
  • Signing and verifying messages with bitcoin address
