    Default chapter 8-1

    Can anyone provide more info on how to do a Column transposition cipher to solve ch 8 ? I've been trying every way possible with no luck. I've spent a week on this with no luck. Thanks for any help as I'm new to this.

    I use the following "guess and test" method:

    write out all the letters in one row.
    pick a number x.
    divide up the letters into x equal-sized rows (except maybe the last row)
    read the columns (either from top to bottom or bottom to top)
    if the columns are gibberish, pick a different x and repeat

    Example:
    XnmfrncnniXeXsaaXciXmasnhXiXxeXkauroopXhselrcXltpi iXtiXpoagoXstcr

    First I guess x=4 and get

    XnmfrncnniXeXsaaX
    ciXmasnhXiXxeXkau
    roopXhselrcXltpii
    XtiXpoagoXstcr


    the columns don't make sense, so I try x=5:

    XnmfrncnniXeX
    saaXciXmasnhX
    iXxeXkauroopX
    hselrcXltpiiX
    tiXpoagoXstcr


    and read the columns from bottom to top, left to right:
    thisXisXanXexampleXforXcrackingXaXcolumnXtransposi tionXcipherXXXX
    A funeral can be real fun if you mix it up a bit

    Hi all,

    If anyone has access to Microsoft Excel and is interested, I've written a tool to help solve transposition ciphers. I've sent it to a few people already and I think they've all found it useful. Or at least I hope they have!

    If anyone wants me to e-mail it to them, PM me.

    Default Poem solved, but #7 Still stumps me

    Wow, that hidden poem was gruesome. If I am not mistaken, it was made harder by a few letters that were missing or wrong. And the last group was not there, but that is not too troublesome. I actually got it by working backwards(as posted elsewhere), by guessing the author's name, then matching up the capital letters with the author's known poems. After transcribing all the text, correcting my errors and massaging it a bit, I got the poem I was suspecting. I wrote computer programs to help with all of this. As a side note, due to this hunt, I researched and actually wrote a program that cracks Playfair ciphers.

    We go from these few that take forever to the absurdly simple, but I do have one of the seemingly simple questions that has me stumped. Can anyone give me a clue as to the answer for #7? The obvious one doesn't fit, nor does any I have been able to come up with.

    Did you read the instructions on the cryptex page? That should help

    Thanks. I knew it had to be something simple I was overlooking.
