class SSHProtocolChecker: (source)
Implements interfaces: twisted.cred.checkers.ICredentialsChecker
SSHProtocolChecker is a checker that requires multiple authentications to succeed. To add a checker, call my registerChecker method with the checker and the interface.
After each successful authenticate, I call my areDone method with the avatar id. To get a list of the successful credentials for an avatar id, use SSHProcotolChecker.successfulCredentials[avatarId]
. If areDone
returns True, the authentication has succeeded.

Part of the ICredentialsChecker
interface. Called by a portal with some credentials to check if they'll authenticate a user. We check the interfaces that the credentials provide against our list of acceptable checkers. If one of them matches, we ask that checker to verify the credentials. If they're valid, we call our _cbGoodAuthentication
method to continue.
Parameters | credentials | the credentials the Portal wants us to verify |
Called if a checker has verified the credentials. We call our areDone
method to see if the whole of the successful authentications are enough. If they are, we return the avatar ID returned by the first checker.
