I want to allow run specify command on my website, through PHP exec() function, so i found the way, to add www-data in sudoers.d files to allow run specify commands without asking password.
I tried next things:
- check where is program catalogue
whereis hashcat -> hashcat: /usr/bin/hashcat
- Add a new file to
sudo visudo /etc/sudoers.d/www-dataand add next line
www-data ALL=(www-data:www-data)NOPASSWD: /user/bin/hashcat
- Try to run it through www-data:
sudo -u www-data sudo hashcatAnd then i get this:
[sudo] password for www-data:, that means it doesn't seems to work
What can i do wrong, and what i should do then? And is my decision to do so correct? Is there a better and safer solution?...

That problem is solved, by removing the
(www-data:www-data) so my "www-data: file in sudoers.d looks like:
www-data ALL=NOPASSWD: /usr/bin/hashcat
Thanks all for answering and give me a hint to solve this! Especially thanks to @cyberbrain for my carelessness!
I am given a hash ("1u9Tc6HX") and the salt ("Ff"), and I am told to crack the password knowing that it has been hashed with DES algorithm. Using hashcat, I have known that the password is ("michael") and I am now trying to hash this password in order to compare it with the hash given. However, I have tried using (openssl enc) command but it always asks me for the password used for encryption, what I am not given, so I don't know how to hash ("michael") using DES and salt ("Ff") and get ("1u9Tc6HX"). I am open to change the procedure and try other things in case you think is easier to crack by other way. (I am working with python) Any comment and help is appreciated.
Pd: Example: Ff1u9Tc6HXxJo Enunciate: The password has been hashed using the DES algorithm. The entry consists in 13 printable ASCII characters, where the two first characters represent the salt. With DES, only the first 8 characters of the password are used....

Passlib is a popular library for password hashing:
I'ld like to calculate a public key from a private key. It must work using OpenCL. It seems hashcat has a nice library but I'm not sure how to use it.
Other libararies are also possible. secp256k1-cl seems to be very difficult to use https://github.com/hhanh00/secp256k1-cl/blob/master/secp256k1.cl
See below an example of how it might work based on inc_ecc_secp256k1.cl.
Should I use
parse_public on the known base point
G to get the coordinates in a
point_mul with my random secret passed via
k and the base point
G passed via
basepoint_precalculated to get the pubkey in

I've found a working solution
I'm trying to do to a test launch of hashcat with these two passwords:...

echo -n instead of
echo otherwise your password will include a trailling
\n (newline character), which Hashcat will not try to match.
I am analysing the amount of hashes cracked over a set period of time. I am looking to save the current status of the crack every 10 seconds.
Recovered........: 132659/296112 (44.80%) Digests, 0/1 (0.00%) Salts Recovered/Time...: CUR:3636,N/A,N/A AVG:141703,8502198,204052756 (Min,Hour,Day) Progress.........: 15287255040/768199139595 (1.99%)
I want these 3 lines of the status saved every 10 seconds or so. Is it possible to do this within hashcat or will I need to make a separate script in python?...
ANSWERAnswered 2020-Apr-13 at 22:56
You can enable printing the status with
--status and you can set the status to prints every X seconds with
--status-timer X. You can see these command line arguments on the hashcat options wiki page, or
hashcat -a 0 -m 0 example.hash example.dict --status --status-timer 10
I'm assuming that you just want to save everything that gets printed by hashcat while it's running. An easy way to do this is just copy everything from stdout into a file. This is a popular s/o question, so we'll just use this answer.
To be safe, let's use
-a which appends to the file, so we don't accidentally overwrite previous runs. All we need to do is put
| tee -a file.txt after our hashcat call.
Give this a shot, it should save all the statuses (and everything else from stdout) to
I'm new to computer security but I'm trying the same to make a toggle case attack starting from a dictionary password.
I read there that it's possible to alternate uppercase and lower case word starting from a dictionary to have all combinations (case sensitive).
I don't know what command to use and 4 now I'm stopped on standard dictionary attack...
