Re: HTTP sniffer for Digest Authentication?

Hello

  Below is a fragment from my access log with a 10-second nonce. Apache
  asks the client to reauthenticate (with a 401 response and a new
  nonce) every 10 seconds.

Yup you correct. I read up on how webserver implement nonce generated
digests, and this seems correct. I guess the nonce has to have a min
lifetime of 10 or more because of the stateless nature of HTTP ??? Maybe
someone can enlighten me on this.

  After extending nonce lifetime, I took a set of request headers
  from the audit log and used them in a new request, and was
  successfully authenticated. I could repeat the process as many
  times as I wanted. That is, until the original nonce expired.

This seems doable, and should be easier, if nonce is set to expire @ 300
sec intervals.


Thanks.
