RTSP Authentication Grinder is provided for testing purposes only and is not authorized for use to conduct malicious, illegal or other nefarious activities.

Standard usage is:

python rtsp_authgrind [- l username | -L username list file] [-p password 
| -P password list file] <target ip [:port]>

Right now I would say it is "fair" speed. I can get 100,000+ credential checks through it in 12-15 min. My opinion is the major limiting factor is the device, not the program, as the device I am testing on seems to saturate at about ~120 checks per second.

A few things to know: 1. rtsp devices can be overwhelmed so these default settings could easily cause an error: "Resource temporarily unavailable". Note there may be a bug that skips the checks when this happens, I am tracking that down.

2. Starving the threads can happen (they block) if the THREADBLOCKSIZE is small. So
if you have 10 threads and a block size of 10, you could get some of those threads
doing a large amount of blocking on getting new work items, versus actually doing
checks. I like the larger block size like 30, 50, 100... But it will have to depend
on the number you have.

3. This ONLY does BASIC auth right now. I have hooks in to do DIGEST auth later (see
to do list)

To Do:

1. Add DIGEST Auth
2. Fix the skips I think are happening when service congestion occurs
3. Fix the reporting... I would like for it to display the current speed and such, but what I originally did was clunky
4. Update to add THREADS and THREADBLOCK sizes to command line params (-t THREADS, -b THREADBLOCK?).
5. General speed and efficiencies
6. Self throttling?
7. Better reporting (like a -o file option that tees)?
