i have a one hccap file and i need hex mask code like ?d?d?d?d?d?d?d?d


specifically   1234567890 - abcdef  8 char like 22dd134f or ff2aad33 or 222edfa7

how can i mask lowercase and digital hex based 8 char...

(im use cudahashcat64.bin)

ty for the help, sorry for language : )]]>

Im quite new to using Hashcat.

My first database I happen to have Im testing against to which I also have the source to how it was hashed is proving more difficult that I thought.

It has been hashed twice as follows. (there is no salt)

$Hash1 = SHA1([password-to-hash);

$Hash2 = SHA1($Hash1);

Now $Hash2 contains something like "FF 12 FE ........" in Hex etc.

Now Hashcat can have a go at this now with the right parameters even though its doubled. (I believe).

The problem I have is that the Hex output of the double hash has been converted to a base 10 Decimal number and that is what is now the hash.

i.e. "FF12FE...." will become: "25518254...." which without some sort of delimiter I cannot convert back to Hex again. (without coding something)

Is there a way to deal with this within Hashcat or do I need to go off and create my own rainbow tables maybe.

I realize this means that SHA256 needs to run two rounds as the input data (pass+salt) is longer than one block.

Currently I'm getting a line exception when i try to use 1400 (with hybrid + mask) or 1410 (sha256($pass.$salt)).]]>

I am looking at some hashcat benchmarks and i noticed that at the crypt function (e.g. md5crypt) it outputs the following

Hashtype: md5crypt, MD5(Unix), FreeBSD MD5, Cisco-IOS MD5

Workload: 1000 loops, 32 accel

Does the workload which is measured in loops have to do with the gpu-loops paramter or it means that we have 1000 ieterations of MD5 algorithm (i.e. MD5(MD5 ..... MD5(string) 1000s MD5s)?


Thank  you very much]]>

If I do real crack it is 10 Kilohashes/second.

How can I specify the character set necessary to find this with hashcat? Shouldn't take too long, it's only 6 characters long.

The following does not work:

$ cudaHashcat64.bin -m 100 -a 3 --custom-charset1=«»Tt€\$ test.txt ?1?1?1?1?1?1

The following actually works, but if I have to specify all 2 and 3 byte characters as potential hex combinations, I'll be wasting a _lot_ of time trying invalid combinations:

$ cudaHashcat64.bin -m 100 -a 3 --custom-charset1=«»Tt€\$ test.txt ?1?1?1?1?1?1?1?1?1?1
