Cracking performance lower than expected? - MA40 - 08-04-2021
Hello.
HashCat always sends me this message:
Code:
Cracking performance lower than expected?
* Update your backend API runtime / driver the right way: https://hashcat.net/faq/wrongdriver
* Create more work items to make use of your parallelization power: https://hashcat.net/faq/moreworkIs this always done as a rule or is it that I have something wrong configured and I have to improve it?
All the best.
RE: Cracking performance lower than expected? - philsmd - 08-05-2021
you need to mention more about what you are trying to do (including the command and the input size: size of dictionary, size of rules etc).
The FAQ (the link) explains it quite good, what the "problem" could be. Sometimes it's not worth to bother too much about this message (depending on the time needed to finish the attack etc), but it's important that you understand that hashcat isn't able to achieve full acceleration with the current command and input (that's the most important part of the warning message). Just read and try to understand

Thanks.
The command is as follows:
Code:
$ ./hashcat.bin -O -m 11300 -a 0 -w 4 -D 1,2 -S -o bitcoin.cracked bitcoin.hashes **********.txtThe dictionary file **********.txt is 21.7 GB.
The bitcoin.hashes file has 86 hashes.
All the best.
Code:
$ ./hashcat.bin --restore
