Cryptocurrency address generator and validator.
*** DO NOT USE THIS TOOL IN PRODUCTION. YOU WILL LOSE YOUR BITCOINS ***
This educational tool explains step-by-step how private and public addresses are generated for the most common cryptocurrencies such as Bitcoin.
It also explains how the Elliptic Curve (EC) is used to create the public addresses.
The following functionalities are implemented in the tool:
- Creating public keys (addresses) and private keys (uncompressed and compressed) for different cryptocurrencies (Bitcoin, Litecoin etc).
All intermediate calculation steps can be seen by enabling checkbox "Show more details".
- Creating paper wallets including QR codes.

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
- Litecoin support
