Disclaimer
This project was written in May 2013 for educational purposes.
Modern cryptocurrency wallets should use hierarchical deterministic (HD) keys instead.
Introduction
btckeygenie is a standalone Bitcoin keypair/address generator written in Go. btckeygenie generates an ECDSA secp256k1 keypair, dumps the public key in compressed and uncompressed Bitcoin address, hexadecimal, and base64 formats, and dumps the private key in Wallet Import Format (WIF), Wallet Import Format Compressed (WIFC), hexadecimal, and base64 formats.
btckeygenie includes a lightweight Go package called btckey to easily generate keypairs, and convert them between compressed and uncompressed varieties of Bitcoin Address, Wallet Import Format, and raw bytes.
