can't crack PBKDF2-HMAC-SHA1 with sample provided - ashimoto - 07-27-2018
Hello there, and I am sorry if that matter has previously been exposed.
I am running hashcat v4.1.0.
In the examples shown there:
https://hashcat.net/wiki/doku.php?id=example_hashes
"sha1:1000:MzU4NTA4MzIzNzA1MDQ=:19ofiY+ahBXhvkDsp0j2ww=="
is supposed to correspond to "hashcat".
However, when I'm trying the example:
echo sha1:1000:MzU4NTA4MzIzNzA1MDQ=:19ofiY+ahBXhvkDsp0j2ww== > sup
echo hashcat > dic
and then, while running:
hashcat64.exe -m 12000 sup dic
I am getting what I attached in the screenshot.
That's why my other hashes are not cracking, as well.
Any workaround/information about this ?
Thanks in advance for your help and attention !
Regards,

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework
