# HDEd25519

Hierarchical Deterministic (HD) Ed25519 derivation using pynacl

## Requirements

```
python>=3.6
pynacl>=1.4.0 # For https://github.com/pyca/pynacl/commit/0e2ae90ac8bdc8f3cddf04d58a71da68678e6816
```

## Usage

```
from HDEd25519_nacl import BIP32Ed25519

mnemonic = "abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about"
((kL, kR), A, c) = BIP32Ed25519.derive_mnemonic("42'/1/2", test_mnemonic)
# (kL, kR) is a private key, A is a public key associated with kL, c is the chaincode
```
