Hex ch and small problem - ccprime - 02-03-2017

hi
now DES is supported but i still have problems to figure out it

Code:
hashcat64.exe -m 14000 "C:\test3des.txt" -w 3 -a 3 -o "C:\test3desresult.txt"

input file looks:

Code:
47DC9810ADE39295:A04AB36B33E34FF2

and from log:

now, when i do like this:

Code:
hashcat64.exe -m 14000 "C:\test3des.txt" -w 3 -a 3 -1 ?b?b?b?b?b?b?b?b -o "C:\test3desresult.txt"

with ?b?b?b?b?b?b?b?b then in log i have:

Code:
Input.Mask.......: ?1?2?2?2?2?2?2?3 [8]

Input.Charset....: -1 ?l?d?u, -2 ?l?d, -3 ?l?d*!$@_, -4 Undefined

it always give's me default charset
how to do it correct ??
and why when i change hash type from 14000 to 14100 i have "Invalid mask" ?? it's only key len diferent
what i do wrong ??

Sad

i read all wiki, faq's, post's etc etc, and i'm still confused Sad

RE: Hex ch and small problem - philsmd - 02-03-2017

It seems that you are mixing up custom charsets (-1 xxx) with the mask itself.
This makes no sense: -a 3 -1 ?b?b?b?b?b?b?b?b

-1 is the same as --custom-charset1 and it is used to define a custom charset (a set of characters)
what you probably wanted instead is to run this:

Code:
hashcat64.exe -m 14000 -a 3 -w 3 -o "C:\test3desresult.txt" "C:\test3des.txt" ?b?b?b?b?b?b?b?b

RE: Hex ch and small problem - philsmd - 02-03-2017

The problem here might be that the keyspace is way too huge and therefore a "integer overflow" is reached. 255^8 = 17878103347812890625 (yeah, a huge number!).

Try with a smaller mask instead...

BTW: you should better use the built-in charset, so something like this:

Code:
hashcat64.exe -m 14000 -a 3 -w 3 --hex-charset -1 charsets/DES_full.charset -o "C:\testdesresult.txt" "C:\testdes.txt" ?1?1?1?1?1?1?1?1

RE: Hex ch and small problem - ccprime - 02-05-2017

thanks Smile

thats works Big Grin

its show me just 3 years on -w 4 Big Grin

w3 show 60 days more Smile

but i still have a question, why we cannot use ?b in cmd line ?
and what about 14100 ? should i DES_full.charset make it double inside ?
now i cannot figure out 14100 :/

RE: Hex ch and small problem - atom - 02-06-2017

?b doesn't make sense because DES strips the highest bit and you'll end up with a 56 bit keyspace. That's what DES_full.charset is optimized for, to search only within this 56 bit keyspace.

RE: Hex ch and small problem - ccprime - 02-07-2017

and what about 3des ?
use the same charset file ?

RE: Hex ch and small problem - ccprime - 02-08-2017

i made few tests, just to check the max time to find key

DES tests:

with those parameters i have 3 years 61 days
-1 charsets/DES_full.charset
?1?1?1?1?1?1?1?1

with this 1 year 59 days
-1 charsets/DES_full.charset
-2 charsets/DES_0_9.charset
?2?1?1?1?1?1?1?1
where DES_0_9.charset is without ABCDEF

Code:

with this 9 days 2 hours
-1 charsets/DES_full.charset
-2 charsets/DES_one_byte.charset
?2?1?1?1?1?1?1?1
where DES_one_byte.charset is only one byte 00

but for 3des when i use
-1 charsets/DES_full.charset
-2 charsets/DES_one_byte.charset
?2?2?2?2?2?2?2?2?2?2?2?2?2?2?2?1
i have

Skipping mask '?2?2?2?2?2?2?2?2?2?2?2?2?2?2?2?1' because it is smaller than the minimum password length

1. how to run 3des ? what i do wrong ? its just a len of key 16 not 8
2. can someone who have x4 1080 show me max time for DES and 3DES ?

This totally makes no sense. Do not confuse a key with a password.

Quote:1. how to run 3des ? what i do wrong ? its just a len of key 16 not 8

For 3des you need a key with exactly 24 octets, not 8. there no way to bf this

Quote:2. can someone who have x4 1080 show me max time for DES and 3DES ?

Here's DES with 4x1080:

As I said, you can't BF 3des keyspace (integer overflow, too).

thx for respond atom@ Wink

now i know lots of more
thx again

btw about 3des and integer overflow/buffer overflow
maybe hashcat should be slower for 3des, not made so many instructions
it can be fixed Smile

is this possible to fix it ?
just to make it work
