    Default Password generator/ crunch

    I'm in trying to figure out how to create a good password list with crunch, I've discovered that most standard wpa passwords I've come across is 10 digits/letters long, with 0-9 and A-G in various combos. Usually 5 numbers and 5 letters. Does anyone know where to download password list like that? anyone know how to filter out useless combos such as 1111111111, 1111111112, 1111111113 etc...???

    you can start with
    ./crunch 10 10 ABCDEFG0123456789
    which will generate a 2.1TB file (17 ^ 10)
    However you said you don't want 1111111111, 1111111112, etc so I would add -p before the charset and see if that is more to your liking. The -p option will generate permutations instead of combinations. However it will generate 17 character long words which probably is not what you want. You might as well just use:
    ./crunch 10 10 ABCDEFG0123456789 and be certain that every combination is checked.

    I am also close to releasing a new version of crunch that has support for specifying the locations of character, numbers, and symbols in the pattern. So if you know that the password is in the format of char, char, num, num, char, sym, num you can use:
    ./crunch 7 7 -t @@$$@^$ ABCDEFG 0123456789 \!\@\#\$\% (yes you need the forward slashes to escape the sequence)

    Sooo....

    would I be right in think that to create a wordist with char/letter/char/letter/char/letter/char/letter I would use:
    ./crunch 8 8 -t @$@$@$@$ abcdefghijklmnopqrstuvwxyz 0123456789 \!\@\#\$\%

    this is exactly what I am after!

    also can I pipe through the input on the fly to aircrack? by simply piping??

    Well you can do the following ;

    Using lower alpha and numeric only in sequence a1a1a1a1
    Code:
    ./crunch 8 8 -f charset.lst lalpha -t @%@%@%@%
    Using upper alpha and numeric only in sequence A1A1A1A1
    Code:
    ./crunch 8 8 -f charset.lst ualpha -t @%@%@%@%
    Using both lower and upper alpha
    Code:
    ./crunch 8 8 -f charset.lst mixalpha -t @%@%@%@%
    You can change the charsets to suit your needs as well as the sequence with the -t option.

    Cheers,

    any help with piping the output into aircrack??

    Thanks again this forum rocks!

    I've worked out how to pipe it into aircrack now but think I would still like to take out some combos for example 0a0a0a6s and things of that nature which are not really feasible as passwords thanks for all the help guys...

    These forums rock hard!!
