Error: (1, 'cannot read key') #342

Hi! I have a problem, when I do this:

key = xmlsec.Key.from_file(p12_path, xmlsec.constants.KeyDataFormatPkcs12, password=pass)

The file .p12 I can extract the private key and certificate whit this:

private_key, certificate, additional_certs = pkcs12.load_key_and_certificates(p12_data, clave.encode("utf-8"))
print("🔐 Private key:", private_key)

And then it print: <cryptography.hazmat.bindings._rust.openssl.rsa.RSAPrivateKey object at 0x73e07a4763d0>

Then, the path is fine, and the file also. What do I am doing wrong? Help, thanks
