    Visual Basic Script

    cscript //nologo scriptname.vbs > letter.txt

    dim a(13)
    startcode=97
    for j = 1 to 13
        a(j) = startcode
    next
    for index=13 to 1 step -1
        thiscode=startcode
        do until thiscode > asc("z")
            a(index)=thiscode
            Mystring = ""
            for j = 1 to 13
                Mystring = mystring & chr(a(j))
            next
            wscript.echo Mystring
            thiscode=thiscode + 1
        loop
    next

    Password generators for DOS and Windows are readily available.
    And some have been written in BATCH  also.
    Code: [Select]
    The folowing is not a true random password, but you can build on it replacing the conditional statement

    @Echo Off
    SetLocal EnableDelayedExpansion
    Set Alpha=abcdefghijklmnopqrstuvwxyz

    For /L %%j in (1,1,8) Do Call :PSW

    Echo Password is [%PSWRD%]
    EndLocal
    GoTo :EOF

    :PSW
    If %random% gtr 10000 (
    Set PSWRD=%PSWRD%%random:~0,1%
    ) else (
    Set /A i=%random:~-1,1%+%random:~1,1%
    If !i! gtr 25 Set i=25
    Set PSWRD=%PSWRD%!Alpha:~%i%,1!
    )
    GoTo :EOF

      Ah, movie password cracker programs... in a real program you would not waste time echoing the trial passwords to the screen... and would anyone choose a password like aaaaagzzzzzzz ?

        If real password (generator) crackers were used in movies it would make for a very very long and boring movie that would go on for days, months, or maybe even years depending on complexity, and might not end in the lifetime of the director! Those scenes where someone gains access in less than 10 seconds and you see characters and or digits scrolling or scrolling and locking on matches is completely ALL HOLLYWOOD!!! The fastest crack would be if it was strictly 13 digits 0 - 9 in which you have 10,000,000,000,000 combinations, but that still would take a long time, just not as long as ones with Alpha involved.

         A good realistic security system in a 007 movie for example with extremely restricted access would probably send a silent alert upon the 5th attempt to enter a password and entering it wrong, should have doors that would lock the person into a controlled space between the last door entered locked shut and the next door they are trying to get past. This system would not allow for the code to be intered unless the door behind them was shut, and sensors could not be overriden which sense for doors position. Then they would get hauled away and likely killed after the 5th wrong password with generator... most people want Bond to Live! ... LOL   So that is why most of the time its a retna scanner with a contact etc, fake fingerprints, and so on for fooling biometric security systems.

        Scenes like Terminator 2 where John Connor rips off an ATM with his friend for arcade money with an account/pin generator are strictly a laugh or "Give me a break" factor for those who know better!!!

        In addition to this, many systems that are used for password authentication in the real world especially for computer or server access will block any further attempts after so many failed attempts were made within a given period of time. Any system not having a lock out is just extremely dumb and left to the movies to display extremely poor security systems.

        I created a table that shows just how complex and how long cracking a 13 character password would be for both Alpha and Alpha-Numeric with a generator that tests ALL COMBINATIONS. With home computers unless you own warehouses full of them and have each one cracking a segment of the whole of all possible combination of possibilities, the odds are greatly against you that it will get cracked in many many lifetimes. The computer is likely to let out its secret smoke long before it gets to a match. However if the password was aaaaaaaaaaaaa and the program started at aaaaaaaaaaaaa and ended at zzzzzzzzzzzzz it would start and find a match immediately, however if it is zzzzzzzzzzzzz it is likely not to happen in your lifetime unless computers become way way more powerful or you have a huge team of systems to use combined processing power of and you allocate smaller chunks of range to generate and test against, and the system that is receiving the password attempts does not get flooded or lock you out. If there is no lockout, there is likely a flood condition where it is overwhelmed, UNLESS you are able to farm the hive of the security system and run this locally at each computer that is looking for a match. The hive being an encrypted  pool of passwords that the real system has and you can test against, its very much not likely to happen in your lifetime.

        That is why dictionary attacks, social engineering someone to giving away the password, keyloggers, exploits by phishing, packet sniffers, etc are used to gain access and password generators are really not the way to go.

        In relation to what you are trying to generate, I generated 4 places with a Perl script using the FOR A to ZZZZ instruction and writing output appended to a file, and it took a while to complete on my netbook. 456,976 combinations in all, and VERY VERY lengthy text file!

        I pretty much wanted to show how unrealistic such a generator was by example  :P

        Password programs use multi-GPU these days and are orders of magnitude faster than a one using a CPU.

        I often forget my passwords and so I need one of these.
