VeraCrypt - no idea what hash or cipher was used

March 27, 2018, 4:09 pm

Used VeraCrypt container for a while now, and don't remember which hash and cipher (definitely was a cascade, but don't remember which) were used when it was created.
Somehow I managed to forget a password, while having a pretty good guess on what an almost correct password is (i think I either forgot couple of letter sequence, or correct keyboard layout, or both), and I've generated a dictionary with couple of thousand combinations of password candidates.
I've started reading tutorials on Vera/TrueCrypt usage of hashcat, but it mentions that I will have to know and use correct hash-cipher combination.
When I use VeraCrypt it doesn't ask me for a hash and cipher. Should I look for another solution, or write my own app that will attempt to mount VeraCrypt through a commandline, feeding it a passwords from my dictionary, or is there a way to use hashcat without knowing hash/cipher, and without trying every possible combination manually?

All academic Services may be a purpose of contact for college students to succeed in universities and colleges. It empowers students by giving them up so far data on latest job trends , high faculties and supports them in admission procedure providing them steering all told necessary aspects from direction towards enrollment, academic finance, assessment, accommodation for the amount of education etc.
We perceive that education determines the career and way forward for student; thus, we tend to serve to place them within the right path thus students attain success in their educational and vocation courses like Engineering and Medical Colleges.
Some Top Engineering colleges and Universities we consult are:

BMS College of Engineering Admission
Dayananda Sagar College of Engineering Admission

PES Institute of Technology admission
Reva University Admission
RV College of Engineering Admission
Christ University direct admission
Dayananda sagar college of engineering direct admission
MS ramaiah institute of technology management quota
RV college of Engineering direct admission

The biggest challenge in today’s world is competition. But I would strongly feel is more than competition it’s the competence which matters more than anything else. In India we have been following the conventional method of education since decades & we have been reasonably successful in making India as better place for education. We have build a strong reputation of being one of the major education hub and one of the most preferred destinations for quality education in India.

7Zip Hash, missing SALT? (Salt-value exception)

I've used 7z2hashcat to create a hash of my 7z file, however, it seems to me that the [salt] seems to come out blank.

Hash:
Code:
$7z$1$19$0$$8$9a82378...
*Note, my hash is like 200kb in size.


When I try to load my hash with hashcat 4.1.0, I get the following error:

Code:

I'm not sure what I've been doing wrong here, I've used the latest's windows build of 7z2hashcat, as well as a git cloned copy for Ubuntu. Both hash outputs seems to be exactly the same.

Appreciate anyone who can help me out.

Hi,

If I know that the password format is:

1 upper case
1 special character
1 number
minimum 10 characters 

So I do not want to submit candidate passwords unless they meet that criteria.

What combination of rules/masks would I use.

Thanks in advance.

Having hashcat check certain websites for known hashes

Hello,

Just wondering if anyone thought this would be a good idea.   Normally, when I have an NTLM hash or an LM hash to crack, I'll hit the web first and search a couple websites that have databases with literally over a trillion known hashes.


What do you guys think if hashcat where to have the option of checking these websites before attempting to crack a hash, to see if it was already cracked, and if it wasn't, if someone did successfully crack a hash, then to submit it to the website?

Just a thought.

Thanks!

md5(abcd[salt])=0efa706032b161be6802d5ae093a97cd
what we know is the [salt] consists of 32 characters ( 0123456789abcdef ), seems like a md5 hash.
now I want crack this salt,
if I try to do this:
Code:
hashcat64 md5_hash.txt -m 0 -a 3 abcd?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h?h
I think it's impossible.


Sometime the [salt] was created by md5(a simple str),
in fact, in this case, the [salt] is md5(simple) = 8dbdda48fb8748d6746f1965824e966a


So, my question is, how can I set the mask to a md5 hash result of itself?
suck as...

Hello,

I have a question about Hashcat,

If i have a cap file with multiple handshake,
Its possible to launch a tread of hashcat wich will try one per one to found the password ?

For example :
wpa.cap -> contain 5 handshake,
used tool cap2hccapx to convert the .cap file to a .cap2hccapx without option.
And launch a Hashcat thread with this .cap2hccapx.
Hashcat will try all handshake ?  or just the first ?

And, how its possible to open a cap2hccapx file ? for see what is content.


Thanks alot !

Radeon HD 5770 - No open Cl found ??? (Half Answerd)

Hi, i recently purchased a Radeon HD 5770 for hashcat use, 

After reading up on the forums i found that i could run this graphics card and that it would work on hashcat also.

I am still convinced this graphics card will work, because of other people running the same card with the same issue i have RESOLVED.

Basically, when i run hashcat in GPU o get the following error


No OPENcl Device found...







BUT My system is showing it with opencl 2.0.4.0



So there should be no issues,



However my system info does not display any openCl either



Iv read up on more threads and find that this is a resolvable issue if i can get the OpenCl rekognized by hashcat.



I find this problem will also occure with other programs not finding the openCl



So i need to sort this out.



Does anybody have any idea of what i should do.



Iv been advised to run hascat 3.2 . which i did.



Still same error.



Is there some sort of tweaking or driver required to make it OpenCl compatible or sumthing.



Here is the link from a guy who had the same card with the same issue..(He resolved it)

Only issue with using OLD Hardware is that your support will be limited. I use to run a 5770 HD prior to my 1070 and had no issues with it. I was able to get ~38-44K h/s for WPA2 on Hashcat 3.20 from my recollection. However, the newest rendition of hashcat may throw errors as it is not OpenCL compliant, so you may need toggle a few parameters to get it to work. Also, using older HCCAP format in older hashcat versions has the possibility of "missing" the correct key just for your knowledge. I have not encounter this issue, but that was the reason for the upgrade to HCCAPX.

Good luck on your venture!

Trying to crack a 7z file I forgot the password for.

Got a hash from it, and successfully tested brute force on it for 1 and 2 character combos:

hashcat64 -m 11600 -a 3 freeze.hash ?a?a --increment --status

now want to try a dictionary attack.

hashcat64 -m 11600 -a 0 freeze.hash rockyou.txt --status

So, this starts up the same way, and I get status updates every 10s or so, and it's saying 89 H/s..

But, progress just sits at 0, and the H/s slowly drops over time.

Truecrypted USB, almost there, tweaking help requested

Hello! thanks in advance for reading.
I am working on decrypting a Truecrypted USB key whose password is only half known to me. I was able to crack a test USB key encrypted with TC using hybrid (+mask) attack, so I know I'm on the right track. As for the target USB key, I have come up with the following command:

Code:
./hashcat64.bin -m 6211 -a 7 -1 ?l?d?u ../liveHash/cryptodisk_sdc1.dd ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 password.txt --increment --increment-min 3

notes: password.txt only has one line and that is the half of the password I do know. increment min to 3 as I've made it there thus far in testing.

My questions:
  • is there a faster way to run this?
  • Is it at all possible to feed the mask portion from a dictionary? I'm reasonably certain the missing half of the password will be in the form of english words, probably lowercase and maybe with a some numbers (likely at the end), but those are all truly unknowns. Likewise, length is unknown.
  • I am pre-pending in this case and will move on to appending if that fails, unless there is a way to do both at once efficiently?
  • in the event a different TC algorithm was used, is it at all possible to set multiple algos for the -m option?

I don't have decent hardware at home (have just tested on my laptop), so I'm looking to invest in something that will allow me to run this efficiently, but I did want to reach out and see if I've at least got the right command for the job at this stage.

Cheers, and thanks again for looking!
