Este repositório contem scripts para geração de endereços de bitcoin capazes de receber moedas.
São scripts de linha de comando:
- Bash
- PowerShell
A proposta é possibilitar a criação de uma Brain Wallet sem necessidade de internet ou aplicativos. O script por si só é o aplicativo (Wallet) que gera as chaves privada (WIF) e pública (endereço para receber moedas).
Seguem os scripts de única linha. Basta copiar e colar no terminal. Para uso real lembre de definir a senha logo na variável que inicia o comando.
Focado em ambiente Linux (testado no Ubuntu). As dependências para a execução são openssl, base58, grep e xxd.

Use a mesma senha no modo Brain Wallet e desmarque "Endereço compactado".
Se os valores não baterem é porque a senha escolhida, após passar pela função de hash SHA256, não atende aos critérios do intervalo limite da curva elíptica secp256k1.
Neste caso tente outra senha.
