I decided to download alot of Wordlists and combine them to one.

Before I start, i like to ask for your advice.

My steps would be:

1. Combine lists to one file
Code:
cat * > out_file.txt

2. Remove whitespaces (this part first, because otherwise grep counts wrong)
Code:
LC_ALL=C tr -d "\11" < in_file.txt > out_file.txt

3. Keep only wanted characters (remove unwanted chars)
Code:
LC_ALL=C tr -cd "\12\15\40-\176\200\247\337\304\344\326\366\334\374" < in_file > out_file.txt

4. Remove words under 8 and over 30 chars, also removes blank lines (everyone with a password over 30 chars deserves it to be safe :) )
Code:
LC_ALL=C grep -x '.\{8,30\}' in_file.txt > out_file.txt

5. Remove duplicates
Code:
LC_ALL=C sort --parallel=10 -S 90% -T /path with enougth space/ -u in_file.txt > out_file.txt

Am I missing something?

Wordlists I like to use:

  • crackstation
    wpa-sec.stanev
    weakpass
    dicass
    Pwdb_Public
    cyclone_hk
    THP_password
    skullsec
    kaonashi

I know masks and rules are better, this is just for the last way out.

Ask 10 people how to compile a wordlist and you'll get a dozen different answers. :)

I recommend experimenting with this until you refine what method works best for you and your available resources.

My 2 cents:
~I've cracked a lot of plaintext with whitespaces in them.
~8-30 char len is ok for wpa2, but there's a lot of < 8 char plaintext out there depending on what password policies were enforced (especially older db's).
~I prefer hashcat/utils/len over grep for scrubbing char length. @Waffle also has a tool 'splitlen' for splitting wordlist by length.
~Some password policies allow special char, so go easy on what you scrub.
~Things like removing whitespace, char length 8-30, scrubbing, etc, are all debatable and can vary depending on the intended application.
~I sort my wordlists by probability, not alphabetically. This makes a big difference in cracking efficiency, especially on slow algos like bcrypt which could run for days on a multi-gigabyte wordlist. Cyclone_hk is sorted by probability, so try testing it against other wordlists that are sorted alphabetically and see which one cracks faster.
~To compare which method works best, try creating several wordlists using differing methods (ex: basewords.txt, char8-30.txt, scrubbed.txt, wordlist_all.txt, sorted_probability.txt, sorted_alphabetically.txt, etc) and then test them against your hash list to see which method works best. Then test your wordlists with different rules to see which wordlist+rule combo works best for your hash list.

I recommend a very useful tool 'rling' by @Waffle for sorting, deduping, counting, etc. Using rling will greatly speed up your wordlist processing.

Here's a list of some of my fav tools:

Thanks for your reply.

That's what i've found. :) so true.

I use other specific unsorted wordlists with rules depending on the case and I know sort by probability is more efficient.
But I didn't see any tool which is able to handle that amount of data and remove duplicates without any problems.

I already found rling but have not tested it yet. Maybe i give it a try.

I only remove non printable characters. My main targets are german passwords. And as you said, it depends on the intended application.

The main thing i'd suggest is having different versions. Having a master wordlist is great but man does it suck how long it takes to run. Also i'd argue a smaller wordlist with a better rule list is better. So be very picky about what wordlists you add I would personally find as many databases/leaks as I could and run a competition to speak (with a predetermined % to crack to be allowed in).

i woud remove Numeric lines too as that can be Brute forced up to 11 or 12 with resealable Rigs Time (working together for 12)
as 8-10 can be check on just about any rig

I thought about it, but I don't know how without messing up. Idea is great. Someone have a solution?

As I said. This list shoud only be the last way out when everything else failed. Already had good results with small wordlists and rules.

Why dont you put all Wordlists into 1 Folder and drag the folder into hashcat , same effect, iam right?

Hi there, Can you tell me please if you know how to customise worldlist in ULM to have words from 8 char to lets say 16 or up. I can see this option. Thanks Kev
Go to 'Downsize' (at the top) then select 'Save items within the range' (on right side)

When you process the list it will ask for lower and upper bound of items to save

know when you are building a list vertically, there is a box you check at bottom to sort and remove dupes.......
