What do you mean when you say you're using plain text passwords? Authentication involves multiple parties handling the password in multiple ways, and the "plain text"-ness of the password changes from step to step. >from hashlib import md5 >md5Password = md5(password).hexdigest() > >then it does not authenticate (I use >credentials.checkMD5Password(password) at the checker class) > >Then after reading > >twisted/spread/pb.py > >I saw that everything is done in the functions: > >respond(challenge, password) >challenge() > >and the methods > >checkMD5Password(self, md5Password) >checkPassword(self, password) > >at the > >class _PortalAuthChallenger(Referenceable, _JellyableAvatarMixin) > >By changing digest() with hexdigest(), it works. > >The question is: > >I there some way to make it work without making changes at the 'pb.py' >module? > >Yes.

You should register an IUsernameHashedPassword checker with the portal you pass to PBServerFactory and use PBClientFactory.login. See pbbenchserver.py and pbbenchclient.py for examples of this. Despite the fact that you're passing a UsernamePassword instance to PBClientFactory.login, the plain text password is never sent over the network. Also, IUsernameMD5Password is about to be deprecated, along with the checkMD5Password method of _PortalAuthChallenger.
