Hi all,
I use FilePasswordDB with a small smtp-server (a very small toy), but when
I use the hash function the authentication doesn't work.
Here few lines of code:
"""
def _hash(name, clearpsw, hashedpsw):
# a very simple hash function ?
return md5.md5(clearpsw).hexdigest()
# return 'aa'
# doesn't work; password file content is correctly "hashed"
smtpusers = checkers.FilePasswordDB('smtppasswords.txt', caseSensitive=True,
hash=_hash, cache=True)
# work! in the file the passwords are in plain text
#smtpusers = checkers.FilePasswordDB('smtppasswords.txt', caseSensitive=True,
cache=True)
mailservice = mail.MailService()
mailservice.setQueue(relaymanager.Queue(QUEUE_PATH))
mailservice.smtpPortal.registerChecker(smtpusers)
smtpserver = mailservice.getESMTPFactory()
application = service.Application("Console SMTP Server")
internet.TCPServer(SMTP_PORT, smtpserver).setServiceParent(application)
"""
The error is:
Failure: twisted.cred.error.UnhandledCredentials: No checker for twisted.cred.
credentials.IUsernameHashedPassword
Obviously FilePasswordDB doesn't provide that credential when there is the
hash function; why smtp connection is hashed and not in plaintext? How can I
get it works?
I found a similar question, with no answer:
