python生成version=0的ec key

您可以使用Python的cryptography库来生成version=0的EC key。以下是一个示例代码：

from cryptography.hazmat.primitives.asymmetric import ec
from cryptography.hazmat.backends import default_backend

# Generate a private key
private_key = ec.generate_private_key(ec.SECP256K1(), default_backend())

# Get the public key
public_key = private_key.public_key()

# Convert the keys to bytes
private_key_bytes = private_key.private_bytes(
    encoding=serialization.Encoding.DER,
    format=serialization.PrivateFormat.PKCS8,
    encryption_algorithm=serialization.NoEncryption()
)
public_key_bytes = public_key.public_bytes(
    encoding=serialization.Encoding.DER,
    format=serialization.PublicFormat.SubjectPublicKeyInfo
)

# Add the version byte to the public key bytes
versioned_public_key = b"\x00" + public_key_bytes

print("Private key:", private_key_bytes.hex())
print("Public key:", versioned_public_key.hex())

请注意，此示例代码使用了SECP256K1曲线生成密钥对，并将公钥的版本字节设置为0。您可以根据自己的需要更改曲线和版本字节。
