wordlist generator !

Hi all.

Is there any sort of wordlist generator. Like i want to create words containing lower case and digits of 8 characters. Is there any tool available in linux to do it ? also can the tool in advance tell me how much space shall be required to store the file.

Kindly guide me

Hi,

After some digging I found an old script I found on-line that creates random words based on some criteria:

Code:

 #!/bin/bash

## word generator : random 'words'

##  with given length, or range

##  with choice of wharacters to be used



chars0="a b c d e f g h i j k l m n o p q r s t u v w x y z"

chars1="A B C D E F G H I J K L M N O P Q R S T U V W X Y Z"

chars2="0 1 2 3 4 5 6 7 8 9"

chars3="& | Ã© @ â¬ \" # ' ( Â§ ^ Ã¨ ! Ã§ { Ã  } ) - _ Â° ^ \" \$ [ ] % Ã¹ Â£ Âµ = + ~ : / ; . , ? "



function increment {

    INPUT=$1

    [[ ${#INPUT} -ge $minlen ]]  && echo $1

    if [[ ${#INPUT} -lt $maxlen ]]; then

          for c in $chars; do

              increment $1$c

          done

    fi

}



function showUsage {

    echo "$0 MAXLEN [MINLEN] [a [A [n [p]]]]"

    echo

    echo "    MAXLEN    integer  Maximum lenght, or specific lengt if MINLEN is omitted"

    echo "    MINLEN    integer  Minimum lenght, equals MAXLEN if omitted"

    echo ""

    echo "    characters:"

    echo "    a    lower case    a-z"

    echo "    A    Uppercase      A-Z"

    echo "    n    numeric        0-9"

    echo "    p    punctuation    . ?" 

}



## argument handler

[[ "$1" = "" ]] && showUsage && exit

maxlen=$1

[[ $2 -eq 0 ]] && minlen=$maxlen || minlen=$2



for arg in "$@"; do

    case $arg in

          a) chars="$chars $chars0" ;;

          A) chars="$chars $chars1" ;;

          n) chars="$chars $chars2" ;;

          p) chars="$chars $chars3" ;;

    esac;

done



#fallback

[[ "$chars" = "" ]] && chars="$chars0"



## kickof



for i in $chars; do

    increment $i

done



exit 0

If you run the script (./word.generator.sh 8 8 a n > 8.char.words.list), you'll get all the permutations.

I don't have a clue how large the created file will be (I'm guessing several hundred Mb, possibly a few Gb). I do know that it will take a long time to generate the output....

Hope this helps.

Well assuming something like 'aaaaaaaa' is acceptable for all lower case and numbers and also assuming that one line per word would mean 10 characters per line (2 for \n),
then I would say about ... 11Tib (give or take)

How do you calculate this? I know there are 36 possibilities at each position and you need 10 chars per permutation (assuming 8 positions). But how to calculate all this to a accurate number?

Thanks in advance.

Well my math was a little rusty, but I used the following:

Code:

((36! / 28!)*10)/1024^4 ~ 11.1Tib

I've been playing with the above and cannot get correct numbers when creating tests. I think it has got to do with XY! not using aaaaaaaa bbbbbbbb etc

0-9 on 2 positions => 100 (10^2) combo's, not (10!/8!) => 90
0-9 on 3 positions => 1000 (10^3) combo's, not (10!/7!) => 720

Took me a while, but after trail and error I came up with this:

Code:

((36^8) * (8+1)) / 1024^4 ~= 23 Tb

Not that the OP will be happier with that number :D

Using: 4 positions, using a-z + 0-9:

Code:

$ ./word.generator.sh 4 4 a n > 4pos.36

$ ls -l 4pos.36 

-rw-r----- 1 druuna internet 8398080 Oct  3 22:27 4pos.36

 $ wc -c 4pos.36 

8398080 4pos.36

$ echo "((36^4) * (4+1))" | bc

8398080

Sorry ... my bad .. was thinking about combinations instead of repeating permutations ... good catch :)

So more than double ... ouch
