Class UsernameSha256PasswordCryptChallenger

source code

Known Subclasses:

I take a username.

Authenticator will give me a salt and challenge me. Requester will respond to the challenge. At that point I'm ready to be used by a checker. The response function used is flumotion.twisted.credentials.cryptRespond()

I implement IUsernameSha256Password.

__provides__(...)

 
Special descriptor for class __provides__

The descriptor caches the implementedBy info, so that
we can get declarations for objects without instance-specific
interfaces a bit quicker.

For example:

  >>> from zope.interface import Interface
  >>> class IFooFactory(Interface):
  ...     pass
  >>> class IFoo(Interface):
  ...     pass
  >>> class C(object):
  ...     implements(IFoo)
  ...     classProvides(IFooFactory)
  >>> [i.getName() for i in C.__provides__]
  ['IFooFactory']

  >>> [i.getName() for i in C().__provides__]
  ['IFoo']
