This guide uses a program and a very dodgy method to bypass the trial limitations. I think it works with all ebooks on vitalsource as it uses the vitalsource web viewer to scrape every page of the book. The program I used is this one: ebook-converter.com/vitalsource-downloader.htm Sadly the trial removes some pages/chapters.
Convert Bookshelf To Pdf
I found out that it only does the removing of chapters after its finished downloading every file from your ebook. Now we can use this to our advantage.
If you go to OEBPS file which is where it downloads the files, mine was in C: Users ComputerUsernameHere Documents eBook Converter VitalSource Downloader temp BookNumberHere epub OEBPS (BTW this file is only created when you're on the page in the program where it asks you to start downloading the ebook) This is where you gotta be quick. While its downloading the book you have to copy and paste all the files out of the OEBPS file. You gotta do this before the whole book finishes downloading as once its finished downloading everything it'll change some files at the end to 1kb files about some bullshit about buying the full version. (looks like this ) For example: the book I was downloading had 16 chapters, so when the chapter 15 file got created I copied and pasted all the files out of the file into another file. The hard part was getting the last chapter as it basically changed the file to the 1kb trial file thing basically instantly.
After a bit of trial and error I was able to open the last chapter up in chrome (as its a.htm file) just before it was changed it. Then I could save it with chrome in my other folder. The final result was all these htm files looking like this Now I just used adobe acrobat XI pro to combine all the files and convert to pdf.
The whole process took me around 10-30mins per book depending on how big the book was. I found this process out myself a few days ago while I was procrastinating so its really not the best, but as of right now there is no other way to download ebooks off vitalsource. The final result is basically the exact same as browsing the book using the proper vital source program, it keeps all the links/redirects to other pages so if you go to the table of contents page and click on something it'll take you to where that thing is. I hope this helps some people. Also to add, after I created the pdf I used adobe acrobats 'Remove hidden information' tool to remove all metadata and hidden text so I could then share all my books to Library Genesis:) There is probably an easier way to do this maybe by running the program in sandboxie and allowing it to write files but not modify. But I haven't really tested anything as I've gotten all the books I've needed for now.
Hopefully someone cracks the program so we won't have to do all this stuff. Should also add, this website sick.bike/How/nodrm, has a link to another program (which doesn't work anymore) made from the same website. They managed to disable watermark.
If they could do this there must be a way to edit the program so it doesn't rewrite the files when finished. I tried to do it myself but all I got to was being able to change the text that gets written to the file. I've had a look at the GitHub you pasted. It is way out of date and nowhere near as advanced as the other program. I tried getting it up and running but the URL's in the script are all messed up. Even still, it only grabs a bunch of images, so it doesn't end up with links and redirects you had. In the next few days I'm going to have a go at making a new program based off of that one with updated values.
I don't think I'll be able to do the links in the book but at least it will be something. Also, I will not be charging for it and I'll make it opensource. I never really tried it I just assumed the dude that PM'd me did, lucky I kept my post!
Good luck with your program. If you get no where you should check and try crack the program if you got any knowledge in that. This program was my final resort in an exhaustive search, but sadly it stamped a huge red watermark on every page of the output PDF unless I bought it. After an investigation into the sorry state of PDF editors, I decided to edit the program itself.
Luckily the author made a typo in the watermark ('Vitalsource' instead of 'VitalSource') and I was able to track down the string to line 236340 of the xxd dump of the vbkdrm.exe file. By replacing the string with null bytes, the watermark can be circumvented. The patched version is available here. They got the same typo in the new program-.

That is clear. My question actually is the following. I can access the e-books from Bookshelf and then I also did download the VitalSource Bookshelf software so I can access the books on my PC. Yet there the printing option seem very limited as to what one can actually print. Now my question is did you access the books in some indirect way so you had the option to save the whole books as PDF all at once? What did you have to open to be able to print the books?
Can you give me a step by step rundown (e.g. I first opened VitalSource-then I selected a book-then I went under print etc.).
I used the Bookshelf access in the browser instead of the VitalSource download, and had to play with the print range to get it to print/save a whole section/reading at a time. I think the largest section I got to print all at once was 200 pages.
I stopped trying to do this when I found the Android and iOS apps for the CFA curriculum, which are actually considerably easier to use than the Bookshelf thing. Can't print from them AFAIK, but I had mostly wanted the PDFs to read on my phone and tablet and the apps worked just fine for that.
I did decide to get the print books for Level 2 after dealing with it all, though.
VBK As of 27 August 2017 it appears this no longer works because VitalSource is enforcing Bookshelf updates. VitalSource Bookshelf needs to be installed, with the book to be cracked viewable in the Bookshelf program. Was my final resort in an exhaustive search, but sadly it stamped a huge red watermark on every page of the output PDF unless I bought it.

Note that this only works with.
I've recently been exposed to VitalSource as a course I'm taking has its primary textbook only available from VitalSource. In any case, I've found Bookshelf to be quite annoying and slow, so I took out some time to figure out the format.vbk Format The.vbk format is, at its core, a container format. It contains all the components of the book, laid out as files in the container.
Pi kappa alpha risk awareness handbook of chemistry. It's sort of like the type of large resource packs you see in games these days. The file is read from the end: there is a 'magic number' that identifies the file as in.vbk format, the size of the header, and the header itself.
The header is an XML string that contains basic information about the file, such as version, built date, file table info, sanity info, and some metadata. The rest of the data are file data as laid out by the filemap. There are currently four distinct categories of book formats that can be contained by the.vbk file.
They are vitalbook, epubbook, picturebook, and pdfbook. VitalBook The vitalbook format (aka DashML) is basically an XML document, stored with VitalSource's proprietary serialization format.

The document has a custom XML schema. Images and videos are stored as file entries in the.vbk container. Patent for the serialization format can be found.
Also of interest is, which includes an old copy of the DTD for the XML, starting on page 35. Last known DTD version is 3.2. EPUBBook The epubbook format is just the contents of an EPUB file put inside a.vbk container, along with search indexing data. The files can be extracted and packed to a Zip file for a valid EPUB book. PictureBook The picturebook format contains images of each page of a book. Alongside those images are a manifest, text contents of each page, metadata file for position of glyphs (for text selection), linebreaks, and links, and index files. This format may be harder to convert to e-book reader formats, considering they're just images.
Probably the best format to convert to is PDF. PDFBook The pdfbook format is basically the same as picturebook, except instead of images of pages, there is a single PDF of the book.
The text content and page metadata files are still generated and included (for whatever reason). The PDF appears to be the same file as is submitted by the publisher.
DRM The DRM used in this system is pretty straightforward. The individual streams inside the.vbk are encrypted with AES-256 CBC as necessary (i.e. Everything except for cover and cover thumbnail). The keys for the files are stored in a license file (oddly, also a.vbk; its password is encrypted with RSA-2048 OAEP and the encrypted password stored in the.vbk's header). The license file is delivered from VitalSource's server, and contains basic account information (name, email, device ID) and book information (password, print and copy limits, expiration date). The patent for the DRM system can be seen.
(Interesting to note, the system in practice deviates slightly from the patent by using a single, static RSA keypair instead of a unique keypair for each user.) While it appears no.vbk is distributed without encryption, it is entirely possible to read one that is not encrypted (I tried it on Bookshelf; although it'll prevent you from opening the file if it doesn't find its ID (derived from file name.) in the license file, a rename did allow the decrypted book to work just fine). Next steps What I'd like is to get VitalBook support in calibre. I've made a utility to decrypt, extract, and convert.vbk files (convert meaning vitalbook to XML, not other types to other formats, though I do have an epubbook to EPUB converter). Unfortunately, it's all written in C#, and I don't know Python, so I can't write a plugin for calibre. Would anyone be interested in bringing support for it to calibre? I'm thinking most basically extracting epubbooks and PDFs for import, and getting metadata from the.vbk header.
(Although the metadata doesn't contain publisher name, publication date, or category info.) Existing converters Although there are no 'offline' converters publicly available right now, there are still ways to convert certain VitalBook variants into other formats. PDFBook: Use the to dump the embedded PDF file. EPUBBook: Use to convert to EPUB. VitalBook and PictureBook: Use a PDF printer to convert to PDF. Note this may be slow, and the resulting pages will include a watermark header and the page quality may be lower.
In the U.S., it is legally dubious thanks to the DMCA. It is legal to create it, and it is legal to possess it, but it may or may not be legal to distribute it (as I understand it, hinging in large part on whether you can convince people that such a book constitutes a 'computer program', making it qualify for a fairly significant loophole).
What you could do, though, is document how the format works, but leave out the de-DRM portions, and let somebody else outside the U.S. Re-reverse-engineer the remaining bits.
