Comment puis-je dériver une clé publique d'une clé privée connue?

Je crois que vouspouvez utiliser PyTezos et à savoir ce Méthode

 @classmethod
def from_key(cls, key, passphrase=''):
    """
    Creates a key object from a base58 encoded key.
    :param key: a public or secret key in base58 encoding
    :param passphrase: the passphrase used if the key provided is an encrypted private key
    """
 

I believe you can use pytezos and namely this method

@classmethod
def from_key(cls, key, passphrase=''):
    """
    Creates a key object from a base58 encoded key.
    :param key: a public or secret key in base58 encoding
    :param passphrase: the passphrase used if the key provided is an encrypted private key
    """
