class Key25519(__builtin__.object)
      __init__(self, secretkey=None, verifyingkey=None, pubkey=None)

          secretkey-->bytes[32]
            verifyingkey-->bytes[32]
          pubkey-->bytes[32]

          A PublicKey version of the object will have ONLY verifyingkey
          and pubkey and signingkey will be None
          A PrivateKey version of the object will have secretkey set
          and verifyingkey and pubkey are ignored and derived from secretkey

          Storing and reusing the secretkey is a way to recreate your key pair
