ZIP Password Recovery

**marex** · Mar 10th, 2001, 06:51 AM

Hi All,

Found this on the net.
Recovers passwords from zip files.

Look at this url

http://ftechsoft.hypermart.net/

Free download.

Tested it on win98 and Win2000 and works fine.

I'm intrested in the benchmarks.

On a PII 300 it was approx: 720000
On a PIII 500 it was approx : 1420000

If you have another pc please let me know your benchmark.

cheers

This looks great! I've been looking for one of these for about a year.

**marex** · Mar 10th, 2001, 10:23 AM

Hi Megatron,

Yes, it is great except for the registration forms. ;-)

It is also time consuming, I'm looking now for a password
of 23 characters!!!

It will take hours before it has been found.

mines goes at 1,300,000 words per sec

now if they could only make one like that for ace :-)

**dimava** · Mar 10th, 2001, 02:14 PM

wow, after i registered it, it goes at around 2-3 million

i have an Athlon 500mhz 130MB ram

Mar 10th, 2001, 02:15 PM

Yes, the registration is annoying...But I think there are ways to bypass it whenever it comes up. e.g: Sending a click message to the button whenever it popus up ;-)

Info

My PIII 500 s busy for about 9hrs and 40 minutes
with a benchmark of 1.2 mil.

I'm still at 0% and the current length is 20.
Mode is Brute Force Attack.

The count for checked passwords is raising and the
current password characters are changing but not
moving to te beginning of the string.

I still have 12 "t" charachters from the beginning,
so after all those time he checked 8.

I wished I had the Athlon or the PIV 1000Mhz

hey guys......have pity on me with my p200mmx
with 64 mb ram

it,ll take weeks.......heh heh

**marex** · Mar 11th, 2001, 03:34 AM

Hi Chopper1

I think you should start it and then leave for a few
weeks on holiday.

It will indeed take a few weeks on a 200mmx.
Can you give me the benchmark, it will be
around 400000 I think.

cheers
Ray

**marex** · Mar 11th, 2001, 05:48 AM

[Dimava]

After registring the program I did not have a
higher speed.

I'm still running on 1200000 on a PIII 500 with 128Mb RAM.

How come you started with 1300000 and after registring
you have 2 / 3 million?

On how many password characters your test was runing,
and on which mode

cheers
Ray

Mar 11th, 2001, 06:49 AM

hi ray.....well its around 366,000 not too good i,m afraid.am trying to overclock with 686mmx software.but will need to get the settings correct.

cheers

john

**marex** · Mar 11th, 2001, 06:55 AM

Hi chopper1,

I've just started a test on a Pentium I 100Mhz

Benchmark give 150000, but it works good as long
as the password isn't greather than 3/4 characters.

cheers
Ray

Mar 11th, 2001, 07:07 AM

hi ray..well on 9 characters it will take 1 year to finish...heh heh

anyone have a good overclock software for a p200mmx by cyrix ?????PLEAASSSEEEEE

john

**dimava** · Mar 11th, 2001, 11:03 AM

so far its been on for almost 10 hours... and it already tried 43 trillion passwords.... Its still searching for the password

**marex** · Mar 11th, 2001, 12:10 PM

At this very moment I have 19 hours 20 minutes.
Current length 20
Always 0%!!!

I wonder if the program is working, the count is
now about 870503759028 !!!

Benchmark : 1245360

cheers
Ray

**Sacofjoea** · Mar 11th, 2001, 12:40 PM

Could someone post a test password zip file? I want to test it..

900mhz Athlon 128mb

**marex** · Mar 11th, 2001, 01:00 PM

You can create a zip file with winzip.

It is very easy to do.

cheers
Ray

**dimava** · Mar 11th, 2001, 02:59 PM

i'll email you a file.. if you get the password, please let me know what it is

**qpabani** · Mar 11th, 2001, 04:51 PM

what if the pass isnt a word?

**dimava** · Mar 11th, 2001, 04:57 PM

it can still find it using brute force... thats why its taking me so long.
so far it has tried 63 trillion passwords in 13 hours and 16min

**Sacofjoea** · Mar 11th, 2001, 06:06 PM

[email protected] email the file.. :-)

**marex** · Mar 12th, 2001, 02:51 AM

Hi All,

I've stopped the program after 35 hours and it have not
giving me the password.

Going to create zip files of my own and do some
testing with different passwords.

One of my zip's password is 3 char long, tested with
brute force, the program said there are more than 7 symbols.

So I think that in the brute force mode something goes wrong.

cheers
Ray

**Lord Orwell** · Mar 12th, 2001, 04:00 AM

The program's help file says that some .zip programs' headers are incompatible with it.

My benchmark on a Duron 750 while surfing the web and running vb and AOL also. (of course 256 meg mem helps here) 1,849,500 (steady and still looking at 21 hours into a 8 character variable-case password)
(and i know amd didnt make a 750 duron- mine is overclocked slightly)

originally posted by chopper1
Anyone know of overclocking software for a pentium 200 by cyrix?

That is about the worst processor you could have in that system. Spring for a amd k6-2 400mhz or whatever and install it yourself. they run about $25
Cyrix 200s dont even really run at 200 mhz. They run at about 180. They use some kind of gay rating they invented themselves to compare themselves to other manufacturers.

**marex** · Mar 12th, 2001, 04:23 AM

Hi Lord Orwell,

True, the program can't read all the headers, but
it is compatible with the winzip files.

So it should find that password in a few hours.

Depending on the lenght of the pasword of course.

I tested on a winzip file with a password of 3 characters
and let him search over a length from 1 to 10.
I tooks about 5 minutes to give me the exact password.
But I noticed that the result came out of the dictionary.
If I use only the "Brute Force" it will take hours to find
it, if he finds it.

Now I testing on different lenghts to see what happens.

cheers
Ray

**Lord Orwell** · Mar 12th, 2001, 05:28 AM

i crashed my computer
I was writing a program to maximize all windows (for another post). Don't try this at home. The result isn't pretty. It even maximized and made visible ole windows and the start button window. Since that window is z-order on top, i had to ctrl-alt-del to close explorer.

**dimava** · Mar 12th, 2001, 07:14 AM

yep, it is taking hours so far its been on for 20hours, and 20 minutes, and it has checked 94billion passwords (brute force). I hope it finds it in the next few days

**marex** · Mar 12th, 2001, 12:55 PM

Hi All,

I'm going to write to the software cy and ask
them some more information.

When I received the answer I'll tell you,
hope there is not a bug in the program.

cheers

hey john......this motherboard will need to be replaced.it only takes up to a 233 mhz processor.oh well time to make a change.........

could i stack 2 ??? heh heh

Benchmarks

Some benchmarks:

Pentium I 100Mhz 150.000 pass/sec
Pentium I 200Mhz 366.000
Pentium II 300Mhz 725.000
Pentium III 500Mhz 1.250.000
Pentium III 700Mhz 1.859.000

Athlon 500Mhz 2-3.000.000 !!

If yoy have others please let me know.

So far my test is running for about 40 hours.
I'm running now on the PIII 700Mhz and let it go
to see if the program really works.
I wanna now!!!

cheers
Ray

**Lord Orwell** · Mar 13th, 2001, 06:45 AM

You can get a Motherboard AND a processor both for quite a bit less than $150. Depending on processor, as low as $100. check out pricewatch.com or motherboard.com. If you can't order on line, shop around in your town. For around $200 you are looking at an Athalon 700, motherboard, and Memory too

My Duron 700 cost $65 2 months ago.

**marex** · Mar 14th, 2001, 04:13 AM

Hi Guys,

I have some bad news I think.

I receive no response from the company.

After some tests with the program I calculated
global time and this is the result.

Suppose you have a password with 10 characters
from a to z.

Now after calculating the total of possible passwords
it gives me : 141167065653376.
This just by taking 26 characters to power 10.

Then on my PC I have a benchmark of 1250000 pass/sec.

So I need 112933677 seconds = 1882228 minutes = 31370,47 hours = 1307,103 days = 3,58 years.

Thinking on my passwor of 28 characters,
I've stopped my computer because this is crazy.

If I'm wrong let me know.

It was to good to be true.

cheers
Ray

**Lord Orwell** · Mar 14th, 2001, 05:39 AM

Well basically each digit is going to make the time required increase by 62 (assuming upper/lowercase letters and numbers only). If an 8 digit pass takes 2 days, then a 9 digit one will take 1/2 a year.

Plus the documentation states that there is a limit on the size of a password it will find.

However, that is why the program is "multi-machine" You and 10 of your buddys all run the program at the same time on different machines and it cuts the time requirement down quite a bit. That way, a 9 digit pass will take 15 days, instead of 150

If you have more than one computer(like i do), then you can see a huge advantage from this feature.

**marex** · Mar 14th, 2001, 05:48 AM

Lord Orwell

Yes that's right, I have 4 computers now running
but still have the problem that my password has
25 characters, so if the program must find that
it takes years.

Maybe considering to buy a mainframe

cheers
Ray

**Lord Orwell** · Mar 14th, 2001, 06:13 AM

How do you know it is 28 characters? Are you simply running a test on a file you created?

**Afroswed** · Mar 14th, 2001, 06:58 AM

any one who can attach a zip(with password) file so i can test the program that u are talking about...
please with a 4 charakters password so it wont seek for days a simpel one pleas then next time u can give me a zip with a harder password.....I am gona kick some as with my Computer ....

**marex** · Mar 14th, 2001, 07:00 AM

Lord Orwell

Yes I put a very long password into the file.
Something like this

" http://www.mypassword2345678 "

So the program has some work to do :-)

I created a vb program to calculate the time
and it is crazy if you see the results.

If you have passwords no longer than 5 chars then it's ok.
I'm testing different benchmarks and characters now.

cheers
ray

**marex** · Mar 14th, 2001, 07:10 AM

Hi Afroswed,

The program works fine with files compressed with
Winzip.

So just create a zip file from any file with winzip
and put a password in it. No bg deal.

Just remember keep the password on max 5 digits. :-)

cheers
Ray

**Afroswed** · Mar 14th, 2001, 07:23 AM

it was not that esay to not make a (zip-pass)
thanx it toke 5 sekends to get the pass with a 4 charcter ,,,,,now i trying to se how long it takes to get the password "anis4idria4anis" it 15 charakter! :O

**marex** · Mar 14th, 2001, 07:40 AM

Afroswed

If you have Winzip on your computer you can
create a zip file with a password.
No big deal.
Just remember to keep the password below 6 chars.

cheers
Ray

**Lord Orwell** · Mar 14th, 2001, 07:15 PM

depends on what you are doing, i suppose. It found my 8 digit multi-case password in less than 2 days.

Also, upon examining the help file, it appears that it is possible to run the program multiple times on the same computer. You might be able to get a speed increase this way, if you have a speedy processor and a lot of ram.
