<h3>Creating New Keys:</h3>
|
||||
<h3>Changes at Barnes & Noble</h3>
|
||||
|
||||
<p>In mid-2014, Barnes & Noble changed the way they generated encryption keys. Instead of deriving the key from the user's name and credit card number, they started generating a random key themselves, sending that key through to devices when they connected to the B&N servers. This means that some users will find that no combination of their name and CC# will work in decrypting their ebooks.</p>
|
||||
|
||||
<p>There is a work-around. B&N's desktop apps for Mac and Windows (nook for Mac/PC, nookStudy) generate a log file that contains the encryption key. For Mac the log file can be found somewhere in [user folder]/Library/Application Support/Barnes & Noble/ and for Windows the log file can be found somewhere in C:\Users\admin\AppData\Roaming\Barnes & Noble\</p>
|
||||
<p>In both cases, the log file will be called BNClientLog.txt</p>
|
||||
<p>You will need to open the application, sign in to your account, and download your books, checking that you can read them in the application, and then quit the application.</p>
|
||||
<p>Then you must open the log file in a text editor and search for CCHashResponseV1. Immediately after that text should be some more text, similar to ccHash: "rLYiGD+vcPoXvsj/87kDAb1AkBy="<p>
|
||||
<p>Copy the text after ccHash, include the " marks. Save it in a new text file, with file name extension .b64</p>
|
||||
<p>Follow the instructions below "Importing Existing Keyfiles:" to import that newly saved file into the preferences.</p>
|
||||
|
||||
<h3>Old instructions: Creating New Keys:</h3>
|
||||
|
||||
<p>On the right-hand side of the plugin’s customization dialog, you will see a button with an icon that looks like a green plus sign (+). Clicking this button will open a new dialog for entering the necessary data to generate a new key.</p>
