multihashing of sha1($salt.$pass) possible? - randyberger - 12-27-2010
Hi,I'm new to this so a simple answer will be helpful
I want to use this command:
Code:
oclHashcat.exe sha1.hash -1 ?d?d ?1?1?1?1?1 ?1?1?1?1?1?1 -m 102where:
sha1.hash is something like this:
Code:

...................and so on,list must have 8x10000 hashes(same 8 hashes with different value inside $salt(the value is some digit in range 0-9999 in hex)!
The target is to obtain 11-digit pass!

Yes, I am pretty sure it is feasible. The question is why you did not try it instead and/or what problem did you get?
I suggest also you modify your order of ?1 and put it like this:
?1?1?1?1?1?1?1?1 ?1?1?1
It's better to have a multiple of 4 in the left section.

First,before i try the above,i must receive one valid hash
alt with password(must happen this days),so can be able to see if the command works or not in some good time-frame,else I'll have to wait with days(80000*10^11 combinations are a lot of computing time)before eventually receive conformation is it correct or not.Also generating a file with those hashalt variables are too much time also for me,because I don't have the knowledge to make some script who will generate it for me at this time!Maybe someone here will help me with this script,maybe not
EDIT:Maybe I do all wrong
for example here is command line for ighashgpu,off course with only one hash,coz ighashgpu does not support multihashing for sha1:ighashgpu.exe -hm:0 /t
ha1 /min:11 /max:11 /uh:00010203040506070809 /salt:0405040200XXXXXXXXXXXXXX00 /h:22E674C15D2DA3C80125CCF661A82BF0F59EDC82 for info:
green text X in salt is value that i know by default;
red text are the values from 0-9999 in HEX(in my case the number is 4542).I must try them until i get match witch will lead me to my 11digit code
orange is my hash(i can get 8 hashes).
So I want to crack simultaneously with those 8 hashes do decrease the time maybe x8 times.If any of these hashes match I'll have my password.
How can I do that?

RE: multihashing of sha1($salt.$pass) possible? - randyberger - 12-29-2010
Updating info.....
So here is correct pair of pass,salt and hash:
tested with this cmd
Code:
ighashgpu.exe /t:sha1 /min:11 /max:11 /uh:00010203040506070809 /salt:07070902003543010412367400 /h:07381fe21f9a4e56740ee3162a7c06e6aad15493
pauseI can not reproduce the result in oclHASHcat,don't know why...this is the command i used:
Code:
oclHashcat.exe hash.hash -1 ?d?d ?1?1?1?1?1?1 ?1?1?1?1?1 -m 102in hash.hash file i have only one line:
Code:
07381fe21f9a4e56740ee3162a7c06e6aad15493:07070902003543010412367400Code:
pass:0709010007050508040804(in hex) or 79107558484
salt:07070902003543010412367400(in hex)
hash:07381fe21f9a4e56740ee3162a7c06e6aad15493here is initial data that i know:
Code:
354301041236740
hash_1:07381fe21f9a4e56740ee3162a7c06e6aad15493
2:6f937b59267113842c9ef56e30be83b6258dd5b8

7:11f341fd9db2aab2ea560dcc00c42b724dc317ac
8:6c0b9c3db41ab03d78464a2462b3dbdbce4b2ec5So..cracking all hashes will lead me to same(or other but still useful) 11-digit password!
About salt( here is the key
)....salt:07070902003543010412367400 where:
random_number _from_00000000-09090909 in hex (0-9999) in my example 07070902 in hex(7792)
00 - zero byte
initial_data in my example 35430104123674
00-zero byte
The target:I must try one hash with salt that has changing random_number _from_00000000-09090909 until i find password 11-digit(22 in HEX)
Every hash has different random_number(in other words different salt) but leads to the same (maybe different but still usable) 11-digit password(not proved yet)!
How to test all 8 hashes simultaneously with current salt is my question??!!!Because 1st match will give me my password!!!Also how to organize all things together....
10x again for contribution!
RE: multihashing of sha1($salt.$pass) possible? - atom - 12-29-2010
sorry, but this does not work with oclHashcat for two reasons:
1. you can not add salts or charsets in hex
2. you can not crack plains of size 15 or bigger and you need 24
RE: multihashing of sha1($salt.$pass) possible? - atom - 01-21-2011
multihashing of sha1($salt.$pass) is (and was) possible but the reasons why sl3 unlocking with oclHashcat is not possible still remain the same even with the latest version.
RE: multihashing of sha1($salt.$pass) possible? - atom - 01-31-2011
support for salted hex and salted charsets comes in oclHashcat v0.26
