please help with crunch command...

[Hoe]

Hi,

I do want a word-list with min 4 and max 8 with a pattern abcd@@@@
So my command would be

crunch 4 8 0123456789 -t abcd@@@@ -o abcd.txt

Crunch will give me an error of minimum must be the same length of the pattern which obviously 8.
Please help me how to get the command right.

so my word-list would produce something like this

abcd1
abcd12
abcd123
abcd1234

Not just like this

abcd1234
abcd4231

Thank You

Man! Is just you READ the error!

for i in `crunch 1 8 1234567890 %`; do echo "abcd$i"; done

Hi,

can you give the actual command, so I can easily follow through... I can't get the command above to work.

crunch 1 8 1234567890 %`; do echo "abcd$i"

Thank You

I dont know where you found it: crunch 1 8 1234567890 %`; do echo "abcd$i"
I think that you have some problem there, I posted this commandi just changed to 3 to dont generate a big output):

root@anubis:~# for i in `crunch 1 3 1234567890 %`; do echo "abcd$i"; done

going off topic here... using crunch with aircrack-ng, does it save the word list? so if i did a 0 to 25 with abcdfghABCDEFGH would that save and use up a lot of my memory? or does aircrack make the list, try it, then delete it on the spot?


(im new to this :P)

[Crash]

Yeah, crunch saves the list.
Just take a look in man/help witch one is the option to do that.

This will work:

crunch 5 5 "0123456789" abcd@ -o File1

crunch 6 6 "0123456789" abcd@@ -o File2

crunch 7 7 "0123456789" abcd@@@ -o File3

crunch 8 8 "0123456789" abcd@@@@ -o File4

A good overview for crunch can be found by searching Crunch A Day With Tape. There are two(2) of these study the later one.

When using with aircrack-ng you can either have crunch write a file to text and then have aircrack-ng access it thru the -w command.

Otherwise you can do a crunch aircrack-ng passthru something like this:

crunch 10 10 "0123456789" | aircrack-ng handshake.cap -b XX:XX:XX:XX:XX:XX -w -

Only do a passthru if the wordlist is so big that you cannot precompute or store it. A passthru slows down the cracking speed.
