.. py:class:: M2CryptoSK(curve: cryptography.hazmat.primitives.asymmetric.ec.EllipticCurve | None = None, keystring: bytes | None = None, filename: str | None = None)

   Bases: :py:obj:`3.0.ipv8.keyvault.keys.PrivateKey`, :py:obj:`3.0.ipv8.keyvault.public.m2crypto.M2CryptoPK`


   A pyca implementation of a secret key, backwards compatible with Dispersy M2Crypto secret keys.


   .. py:method:: pub() -> 3.0.ipv8.keyvault.public.m2crypto.M2CryptoPK

      Get the public key for this secret key.



   .. py:method:: has_secret_key() -> bool

      Is this is a secret key (yes it is)?



   .. py:method:: key_to_pem() -> bytes

      Convert a key to the PEM format.



   .. py:method:: key_from_pem(pem: bytes) -> cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey

      Load a key from a pem certificate.

      :param pem: the PEM formatted private key



   .. py:method:: signature(msg: bytes) -> bytes

      Create a signature for a message in a backwards compatible fashion.

      :param msg: the message to sign
