Part of twisted.conch.checkers View Source View In Hierarchy

Implements interfaces: twisted.cred.checkers.ICredentialsChecker

Checker that authenticates SSH public keys, based on public keys listed in authorized_keys and authorized_keys2 files in user .ssh/ directories.
Method requestAvatarId
Method checkKey Retrieve the keys of the user specified by the credentials, and check
Method _cbRequestAvatarId Check whether the credentials themselves are valid, now that we know
Method _ebRequestAvatarId Undocumented

from twisted.cred.checkers.ICredentialsChecker
