class Bip32KholawEd25519MstKeyGenerator

Bases: IBip32MstKeyGenerator

BIP32 Khovratovich/Law ed25519 master key generator class. It allows master keys generation in according to BIP32 Khovratovich/Law for ed25519 curve.

classmethod GenerateFromSeed(seed_bytes: bytes) → Tuple[bytes, bytes]

Generate a master key from the specified seed.

Parameters:

seed_bytes (bytes) – Seed bytes

Returns:

Private key bytes (index 0) and chain code bytes (index 1)

Return type:

tuple[bytes, bytes]

Raises:

• Bip32KeyError – If the seed is not suitable for master key generation

• ValueError – If seed length is not valid
