hashcat Forum

Hello

I'm new to hashcat and I wanted to use it to find out a salt, because I know what is hashed and the hash but I missing the salt. How can do it with hashcat? I have to create a file with the hashed text and the hash and then use the brute force attack?

Thanks for the help

It depends on what algorithm was used. Sometimes it's possible to put as input the Hashass as if it was Hash:Salt in order to crack the salt.

Thanks for the reply, any way it's not a password, the hash algorithm is md5 and it's used as checksum, for this reason I know the text and its hash but I need to find out the salt.

So I create a file with the hash:text only and then I use the command:

hashcat -m 10 -a 3 mytexthashfile.txt

I suppose that the format is salt.pass, because I try to find the salt I have to use the reverse one, this means pass.salt mode, am I correct?
Moreover I think that the salt is just plain text with no upper case, numbers and special chars, do I have to specify a custom charset?

Thanks

I'm try to figure it out but it don't get it. I have made a test, let's say that the the salt is "md5" and the text is "function", I just create the hash for "md5function" and put it in a test.txt file, then I create a second file with the text "function" and I call it pass.txt.
Now I want to find the "md5" salt and I use the following command:

hashcat -m 10 -a 3 -e pass.txt test.txt ?a?a?a

But it doesn't find it, what is wrong?

works for me

Thanks it was using the pass.txt as hash file, now it works:

hashcat-cli64.exe -m 10 -a 3 --salt-file=pass.txt test.txt ?a?a?a
