CEB to remove print shielding combat

First, the text

I've suddenly been hooked on homemade operating systems (actually trying to challenge myself), but I don't think there's enough information. Buy it. I'm a poor VC programmer hands not a few two silver, next E-book bar ... I think colleagues who often go to the book station for free should know what it feels like. But in a series of books there are always two e-books on the internet can not find, so I a hard-hearted when the Spring Festival company Hair 200RMB didn't take, in www.china-xxx.com bought 1100 download currency to go down.

Download is not cheap Ah, one is about 300, my 1000 only enough 3. And I've never been down before, but the e-book from the station in the D version is in PDF format and I think it's probably right now. Did not expect to pay the download currency, into the download page I have Meng, to install what Apabi, and must be through the Apabi under the book to see, in the middle of what registration, authorization certificates and so on. Pretend it, register it, fortunately do not silver, and Apabi download interface to give the download URL (after my verification, if directly with FlashGet download from the URL, get the data and by the Apabi down to the very different), but the irritating is that the station is only allowed in the three separate machines to download, and the account information only retained for six months, God, for me this 3-year jump 7 back trough of the "heterogeneous" which is enough ah? But I still have a solution, that is-Qiang Qiang-we cracked version of the Super Star A group of sharp weapons--flashpaper!

But...... When I opened the ebook with a happy look ... What about my cute "print" Item? Look carefully, in the "menu" does have "print", unfortunately--not with M (-|-) M what's going on? I don't have to pay for this edition, so I won't use it? Look at it with the description of the CBE file, you can use the "print" Item ah, it seems to be produced when the seal?

What to do? In cases where there is nothing to do with the cool dog poison, in an attempt to use VC call Apabi provided by the OCX, I would like to use the official production tools on the same file processing and then compare to find the mark of the seal printing, unfortunately the official production software only make the CE version of (xeb file).

I want to keep it under the Barina, maybe someday a man of God will come to save me. Or put down the free section on the station (for the sake of the safe passage of my first charge section). Free chapter of the download does not need to Apabi, is directly a RAR file, I think this time it is a PDF, did not expect to untie a look or cbe$%@#@%@%$. Suddenly I thought, not through the Apabi,rar only one file without authorization certificate, perhaps ... Sure enough, free chapters can print!!!!!! (a company development department in a remote corner issued Chenyuluoyan laugh) really wise thousand worry, must have a loss! For the same book, with the same software for the compression of its parameters must be 99% the same, for this situation is free and charge the parameter is only in the printing and licensing of different, and the parameters are generally in front of the file, as long as the charge and no charge of the section of the file head comparison, You can find the printed flag bit (as long as it does not encrypt the sign bit).

The following is a comparison of two cryptographic chapters:

The following are the results of the encryption section and the free chapter comparison:
