Module yawPyCrypto.Key

Key.py

Key

Main class which wraps the PyCrypto public key functionality into an easier to use interface. This class is able to deal with all public key algorithms supported by PyCrypto.

The class does more than wrap PyCrypto keys, though. It offers support for key arguments (basically an instance of the Key class supports dictionary style assignments), which are stored along with the key, signed by it if the key has a private key. The values, which can be stored as key arguments, can be any instance which is serializable by the Flatten library.
