Hi

I wonder why i get this error " Signature unmatched No hashes loaded." ?

 

C:\john-1.9.0-jumbo-1-win64\run>perl 7z2john.pl Secret.7z > Secret.hash

C:\john-1.9.0-jumbo-1-win64\run>


Then


C:\hashcat-6.1.1>hashcat.exe -a 3 -m 11600 Secret.hash ?a?a?a?a?a?a?a?a --force
hashcat (v6.1.1) starting...

Does the format of the outputted hash match what's shown in the examples?

https://hashcat.net/wiki/doku.php?id=example_hashes

 

Is this a test file or something you've obtained?

@omnius This is test file and I zipped with 7z.

The 7-Zip has hashmode 11600

Does the outputted hash match the format provided in the examples?

It looks like your hash starts with "Secret", if the filename is inside your .hash file I would remove it.

 

Try using this to extract the hash instead, there is a Perl and .exe version.

@omnius The outputted hash is: Secret.7z:$7z$2$19$0$$16$08675781a95ffc88d93699ad0cf8beb4$....

I testet  with Secret.7z I got the error above.

Thanks for your link I'm using 7z2hashcat

$7z$2$19$0$$16$08675781a95ffc88d93699ad0cf8beb4$

But this time got this message

C:\hashcat-6.1.1>hashcat -a 3 -m 11600 Secret.hash ?a?a?a?a?a?a?a?av --force

I don't see an error in that output, but that 'v' at the end of your mask might be breaking something?

You could try adding -O as I think that reduces you to around 24 chars but improves speed.

Could you please identify your current issue?

It started out as a signature failure, but that seems to have been sorted out. Aas far as I can see from your latest post, you've got everything working. What is it that you think is wrong, and what should it be instead, in your opinion?

That looks to be working, you are however trying to crack on what looks like an on-board GPU. Which is why it says it will take so long to crack. 

7zip is a very slow algo to crack, especially with mask attacks. Since you created the zip, you could try making the mask "match" your password e.g. ?u?l?l?l?d?d?s?s. Though I fear this will still take a very long time with an onboard card.
