Go utilities for generating hierarchical deterministic Bitcoin wallets based on BIP 32

Go HD Wallet tools

• BIP32 - https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki
• Documentation - http://godoc.org/github.com/WeMeetAgain/go-hdwallet

Get this library

    go get github.com/WeMeetAgain/go-hdwallet

Example

    // Generate a random 256 bit seed
    seed, err := hdwallet.GenSeed(256)
    
    // Create a master private key
    masterprv := hdwallet.MasterKey(seed)
    
    // Convert a private key to public key
    masterpub := masterprv.Pub()
    
    // Generate new child key based on private or public key
    childprv, err := masterprv.Child(0)
    childpub, err := masterpub.Child(0)
    
    // Create bitcoin address from public key
    address := childpub.Address()

    // Convenience string -> string Child and ToAddress functions
    walletstring := childpub.String()
    childstring, err := hdwallet.StringChild(walletstring,0)
    childaddress, err := hdwallet.StringAddress(childstring)
