Hierarchical deterministic key derivation library, as described in BIP-0032. Supports BIP-0043 and BIP-0044 (Multi-Account hierarchy).
Generating a new master key:
seed := make([]byte, 32)
rand.Read(seed)
key := hdkeys.NewMasterKey(seed)
Serializing / exporting a key:
encoded := key.SerializeEncode()
fmt.Println(encoded) // eg. "xprv9s21ZrQH143K2PXAG98v5UhDdHawJG1DsV8DJrc76VTV7n2c8ZyN3VDkEAPBKcBL7BQssWqPFgVZN5rktZZSd8j37PtzLaGx7tVNWtF8i5S"
Deriving a child key:
child, err := k.Child(0)
hardenedChild, err := k.Child(0 + 1<<31)
Getting the public version of a private key:
pubKey := prvKey.Public()
fmt.Println(pubKey.IsPublic()) // "true"
Getting the address of a key:
addr := key.PublicKeyHashEncode()
fmt.Println(addr) // "1AvqrWZtrKgJEJh1PStbHLMQ1Bk7N22GyJ"
Generating BIP-0044 style addresses at the format m / purpose' / coin_type' / account' / change / address_index
key, err := masterKey.Chain("m/44'/0'/0'/0/0")
