Remove DRM from PDF files protected by Vitrium (protectedpdf.com)?


 
Just want to be able to read my university's ebooks on my iPad and they are UID/PW protected. the PDF's indicate they are using Protectedpdf made by a company called Vitrium
Code:
http://www.protectedpdf.com/sbe/sbehowitworks/
Anyway around this?

Only way I have found around it is to print the PDF to an XPS file and then use Adobe Acrobat (9 or X is what I tried it on) to create a new PDF file from the XPS file you just created. Its a long process but it's the only way I have found around the Vitrium Protectedpdf DRM.

What about printing to PDF directly using virtual PDF printer software like freeware PDFCreator?

Not sure if that will work. I use Acrobat and it will not allow you to print a protected PDF to another unprotected PDF. Its worth trying to using other software such as PDFCreator, CutePDF or similar software.

CutePDF results are as follows:

ERROR: undefined

You my friend are genius, thank you it worked like a charm! Simple straight forward and it didn’t take all that long either.
Thanks

ETrip, what worked? I've tried with PDFCreator and CutePDF. None of them worked for me.

I followed this then pushed it to HTML from Acrobat.
Viewing in hex editor the font coding is 3 bytes [8C EF XX] instead of normal 1 byte [YY] per character, a capital A would be XX=9F and YY=41. XX descends 1 while YY increase 1 per character [Reverse mapping]

I can do a slow HEX search and replace with NotePad++ but this is painful and time consuming, anybody know a program that can do such HTML editing where I could us a macro or script or look up table to do the conversion?
