Remove DRM protection from epub and PDF files





Disclaimer: I did not pen the programs mentioned in this post. I simply collect the notice on the Internet, which can be found easily with Google exploration. I think DRM is bad, but piracy is not good one and the other.

If you have an epub or PDF file with DRM passport, you may find it annoying because you are now allowed to interpret the file past a certain number of days, or you cannot press it to read on paper. It turns out that removing DRM from every epub or PDF file is not difficult. Some person (or persons) wrote three Python programs to bestow that. Using them is very easy. The original post (of the father, I suppose) is here.

I assume you already have Adobe Digital Edition installed and your computer was already registered (so that you can read DRM’ed files).

First, you ~iness to have Python installed in your system. You also need a Python library called PyCrypto. The easiest passage to install both Python and PyCrypto is to download and induct the Enthought Python Distribution. If you use Linux or Mac, Python is repeatedly pre-installed.

Second, you need to download the Python programs to put out DRM: ineptkey.pyw for retrieving the key, ineptepub.pyw to decrypt epub files, and ineptpdf.pyw to decrypt PDF files. All these programs be possible to be found easily on the Internet. Just ask Google.

Third, one time you have downloaded ineptkey.pyw, run it and it will indite the key to a file named adeptkey.der in the same folder. In case you don’t know how to cast a Python program, just open the shell, change to the folder of the program you wish for to run, and type ‘python <name of the program file>’ followed by <ENTER>.

Let’s recite you have an epub file from which you want to change of place. the DRM protection. Run ineptepub.pyw, select the input file and give the name of the output file, then click ‘Decrypt’. For PDF files, use ineptpdf.pyw instead.

Some people claimed that ebooks without DRM be directed better than DRM’ed files. I think it doesn’t form sense. Probably it’s a bug of their reader software or devices.
