Three steps to make an encrypted ebook

The biggest drawback of e-books is the inability to effectively protect copyright, which anyone can freely view and copy, which is certainly unacceptable for users trying to sell e-books over the internet. Can e-books have some use restrictions like shareware? Recently, I found a very good encryption ebook maker--ebook Studio (download address It can use password protection, reading time and number of expiration protection, relevant chapter content protection and other ways to limit the unauthorized users to read, With it we can provide user-specific registration code as the serial number of the software to be used for charge management.

I. Making encrypted e-books

The first step of the software's main interface, click on the "Select Path" in the "Browse" button to select the path to save the HTML document, and then click "Select Home" in the "Browse" to select the HTML file as the first page, and then you can preview in the "File structure settings" below the book structure of the ebook, Click the arrows in the upper and lower directions to adjust the order of the chapters, for easy reading, it is best to rename the HTML file as a chapter title, just click "Convert file to title"/"Convert all to title";

In the second step, there are three ways to protect your ebook, namely, password protection, time protection and number protection, and when you choose "unprotected", you can see the similarities and differences of the three protection modes in the right area. Here I take "password protection" as an example.

Select "Password protection" to open the window, we can either encrypt the entire book, or only specific pages can be protected, which can be set in the "protected by" area.

The Password Type drop-down list in the password composition area allows you to choose the specific encryption method:

"Single password" is the simplest way to encrypt, we can enter a password in the "Password" input box below, as soon as the reader reads the password.

Note: Check "Store password information to the reader local", the reader only need to enter the password once, otherwise each reading will require a password. The following are the same.

The second is "User name password", the reader needs to provide you with the user name via email, etc., we use the Registration code generator (the software is included) to generate a different password for each user name;

The third is "machine serial number + password", it is similar to the second, but by different computers to distinguish the user, the reader needs to provide you with "machine code", we generate the password according to the machine code.

The second to third type of encryption method is quite similar, the specific choice of which depends on the individual needs. Here the author chooses "Machine serial number + password".

In the third step, click Output file, click Browse to select the save path and file name for the e-book, and then click Generate to compile the ebook that generated the EXE format.

Finally, be sure to click the "Save Project" button on the toolbar to save the project as EBP file, which will be used later when the registration code is generated.

Two. Generate Registration code

If your ebook is popular, readers will soon be looking for you to sign up. What are you waiting for? Get the registration code to someone else!

Execute the "protection"/"Registration code Generator", open the dialog shown in Figure 3, click "Get through ebook Engineering" To select the EBP project file to get the ebook encoding, then click Next, Open the dialog box, enter the machine code the reader sent you, click Add, and then click "Generate Registration Code", You can get the registration code, export it to a text file, sent directly to the registered user, OK, your first business even completed.
