nanoKeyManager

A go module to generate or manipulate addresses for the crytpocurrenty nano.

Features:

• Can generate cryptographically safe addresses
• Can derive public addresses and their ascii counterparts
• Can translate seeds to/from bip39 mnemonics
• Can derive any address from its seed and index

Examples

Generate a new seed

var seed nanoKeyManger.Key

// Generates a new seed. Defaults to index 0.
nanoKeyManger.GenerateSeed(&seed)
// Print address of index 0.
fmt.Println(seed)

Derive keys with a given seed

var seed nanoKeyManger.Key
seed.Seed = userInputSeed
seed.Index = userInputIndex

// Derive public keys based on seed/index
nanoKeyManager.SeedToKeys(&seed)
fmt.Println(seed)

Derive public key from ascii address

var nanoAddress string
var pubKey []byte
var err error

nanoAddress = userAddress

pubKey, err = nanoKeyManager.AddressToPubKey(nanoAddress)
if (err != nil) {
  // Handle error
}

// Now go in reverse
var reDerivedAddress string

reDerivedAddress, err = nanoKeyManager.PubKeyToAddress(pubKey)
if (err != nil) {
  // Handle error
}

// reDerivedAddress == nanoAddress
