    Hi Phil

    Question 2
    I used bpx getdlgitentexta to break the program then one f12 to get to the zipfile.
    when you f10 into the file you all of a sudden land in kernel.
    Just f12 through it back to the zipfile and the next step you will again land in kernel but f12 through it and you will be in the zipfile where you can start to investigate the code.

    Question 1

    I know that the password it works with must be 12 as I made two zip files with the same text file but with one character in the password different (capitalized)
    Then I did a file comparison on the two files and found only 20 bytes different between the two.
    At 4052BF push [ebp+08] it reads 12 of these characters only likewise at 401015 -401020 only 12 characters are moved.
    So logically 12 characters must be the length of the encrypted password.

    Hope that answers your questions.
