Cardano Byron legacy master key generator class. It allows master keys generation in according to Cardano Byron (legacy, used by old versions of Daedalus).

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
