python error message

Hi Folks,

I’m using a fresh KALI installation. When I use commands like “ldapdomaindump” or “crackmapexec” I get errors like these:

Traceback (most recent call last):

File “/usr/lib/python3.8/hmac.py”, line 51, in init
raise TypeError(“Missing required parameter ‘digestmod’.”)
TypeError: Missing required parameter ‘digestmod’.

Every time it has something to do with “parameter digestmod”.

I guess it goes into this direction : ValueError('`digestmod` is required.') in Pytthon3.8 · Issue #702 · fortra/impacket · GitHub

But I don’t know what to do, because I’m using a fresh and clean installation of Kali. I already tried things like “apt-get update / upgrade” + “pip3 install impact”. But nothing helped.

Any idea ?

Thanks in advance,
Raphael

Maybe you have to install impacket instead impact (or it’s a typo)?
pip3 install impacket

I had the same error from CME when i first installed it. I updated all Python packages using pip3 install -U and that got it running

The below seemed to fix it -

pip3 list --outdated --format=freeze | grep -v ‘^-e’ | cut -d = -f 1 | xargs -n1 pip3 install -U

Thank you greyhatyosh, this worked perfectly. How did you come up with this long command?

working for me too. Thank a lot @greyhatyosh

If you tried the appeal method and still failed, I suggest you use the same method as mine

Download CrackMapExec/requirements.txt at master · Porchetta-Industries/CrackMapExec · GitHub

Then install with pip3

do what > @backK said:

Download https://github.com/byt3bl33d3r/CrackMapExec/blob/master/requirements.txt

Then install with pip3

If you guys getting the same error even after doing this ! Its the issue with impacket. Make sure you have the latest and try this command it worked for me :smiley:

pip3 install impacket --upgrade --user

This was a pain in the ■■■. One of the above steps worked. I did @greyhatyosh steps (thank you!) and also did an impacket update. I would just like to add - make sure you reboot your machine after installing everything.

I had the same problem, thanks to @greyhatyosh’s tips it was solved.
Thanks a lot @greyhatyosh.

I experience the same but tips doesn’t work properly. What I found out is after run this I had crackmapexec 5.0.2 but the last binary is 5.1.1. so, I download the binary and it works fine.
