Challenge Books for study

[leonardonhesi]

Hello LaDidi

The rar file attached to the post really has no password.
".. the. ReverseBooks.exe NET exe file does not accept" reversing "the password."
In fact, the challenge is to discover passwords through reverse engineering, to get the links to download the PDF, the password I mentioned "reversing" will be used only after the breakdown of the challenge,this password is to unzip the pdf books..
As my native language is Portuguese of Brazil (pt/br) all strings in the executable are PT/BR.

Thank you and good luck
