xHD Wallet API Typescript
Typescript implementation of BIP32-Ed25519 Hierarchical Deterministic Keys over a Non-linear Keyspace for Algorand's ARC-52
The implementation is based on the BIP32-ed25519 specification.
Variants
It offers 2 modes to derive keys.
- Khovratovich; Standard mode according to the paper above.
- Peikert's: Ammendment to the standard mode to allow for a more secure derivation of keys by giving more entropy to
zL
. This is the default mode of this library
Sensitive Data
Instances of the XHDWalletAPI
class do not persist sensitive data. However, many methods of the class require the rootKey
be passed as a parameter. The responsibility of handling the seed
and derived rootKey
in a secure manner is on the developer of the consuming application. Variables used to hold these sensitive values should be zeroed as soon as they are no longer needed.
async function example() {
const seed = getSeed();
const rootKey = fromSeed(seed);
seed.fill(0);
const cryptoService = new XHDWalletAPI();
const key = await cryptoService.keyGen(rootKey, KeyContext.Address, 0, 0);
rootKey.fill(0);
}
