Hi all,

I'm currently in the process of re-creating the 3 projects I have for MD5, NTLM and SHA1.

This will mean I'll have in each: 43,745,204,840 (166.46 GB)
Giving me a total size of: 131,235,614,520 (499.39GB)

Average bytes / password: 4.09

The other good feature is the new indexing I have created, I should be getting sub 50 m/s for every request now so will be a lot faster as well as being bigger.

Index is in 3 parts: File Index, Block Index and lastly a Word Index.

Watch this space It will take a few days to generate but will be updated and online soon.

I am also now looking at creating a new MD5 project which will contain ALL my wordlists. This will have 2 indexes and use data compression:

File Index and Block Index.

I've already calculated the lookup time should be ~ 15 - 20 m/s

Sounds good!

Will you remove duplicates automatically? Are you just doing native hashes, or are you looking at pre-solved salted variants as well?

Some basic code I wrote a while back (I think I spoke to you about it at that time) does MD5, MD5x02, MD5x03 and MD5UCx02. It's reasonably fast, taking about 18 seconds to search through 3.2 billion words (many duplicates) in 106 separate files, looking for a single MD5 value. Looking for all 4 types of hashes increases the time somewhat, to about 67 seconds. The overhead is 3 bytes per words, per hash type (plus some headers); for example, the 10K most common password file is 73K on my system, and the index file for it is 164,096 bytes, covering all 4 hash types.

Separately, I wrote some code to start dealing with my &quotsolved&quot hashes. Today, that is about 900 million solutions, of almost 400 different hash types. Primarily, this was to aid in the solutions for hashes without salt, which has been a real pain in my side. As a side benefit, it allows me to see all of the lists on my system which have the same hash value in them - this can often suggest new approaches to lists of &quotunknown&quot hash types. It's pretty fast as well; I can look for 100 hashes through the 900M in about 8 seconds.

Neither of these has been optimized; they use the stock library MD5/SHA1 functions, so there is lots of room for improvement.

And last, I've been working for the last few weeks on mdxfind, which is a more generic hash solver. Currently, it is able to process about 400 different hash types, plus more than 50 variants of each hash type. While it is quite fast, it is not for the casual user, and isn't a replacement for oclHashcat by any means. What it can do is handle really large lists, very quickly. The primary use of it is in solving the &quotunusual&quot hashes, like MD5x10000 (that's how I found one MD5x3992000, 728ae577f4f5fcd6c0b1b1b2ba80990f:admin, for example). The other interesting thing it does is try many different algorithms, at the same time. This is particularly useful for the &quotcombination&quot lists like 32_hex and 40_hex. Of course, it handles all the standard rule files, and such.

Let me know if you want to collaborate on any of this.

OK, the MD5 project is nearly done. The sort function is currently finishing it off but I've tested and the request times are insain! Less than 15 m/s lol, proper crazy fast.

Code:
Trying: hg28s8
DB Time: 1.6561 m/s

Press a key...

OK, the new projects are up and I'm proud to announce that md5decrypter now has 131.235 billion hashes in total across 3 projects consisting of MD5, NTLM and SHA1.

Due to the epic speeds I can now get, I've upped the hash list limit to 32 and I might increase it again to 64 soon.

I am glad to hear this!
