Installation
------------
-Do **NOT** select "Get plugins to enhance calibre" as this is reserved for "official" calibre plugins, instead select "Change calibre behavior" to go to Calibre's Preferences page. Under "Advanced" click on the Plugins button. Use the "Load plugin from file" button to select the plugin's zip file (ignobleepub_v02.5_plugin.zip) and click the 'Add' button. Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.

Click 'Yes' in the the "Are you sure?" dialog. Click OK in the "Success" dialog.
Customization
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.
* Unique Key Name: this is a unique name you choose to help you identify the key after it's created. This name will show in the list of configured keys. Choose something that will help you remember the data (name, cc#) it was created with.
-* Your Name: Your name as set in your Barnes & Noble account, My Account page, directly under PERSONAL INFORMATION. It is usually just your first name and last name separated by a space. This name will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences.
+* Your Name: Your name as set in your Barnes & Noble account, My Account page, directly under PERSONAL INFORMATION. It is usually just your first name and last name separated by a space. This name will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences. For some B&N accounts, the name to use is the name used in the default shipping address. For some B&N accounts, the name to use is the name used for the default Credit Card.
* Credit Card number: this is the credit card number that was set as default with Barnes & Noble at the time of download. Nothing fancy here; no dashes or spaces ... just the 16 (15?) digits. Again... this number will not be stored anywhere on your computer or in calibre. It will only be used in the creation of the one-way hash/key that's stored in the preferences.
Click the 'OK" button to create and store the generated key. Or Cancel if you didn't want to create a key.

-# Revision history:
-# 1 - Initial release
-# 2 - Added OS X support by using OpenSSL when available
-# 3 - screen out improper key lengths to prevent segfaults on Linux
-# 3.1 - Allow Windows versions of libcrypto to be found
-# 3.2 - add support for encoding to 'utf-8' when building up list of files to cecrypt from encryption.xml
-# 3.3 - On Windows try PyCrypto first and OpenSSL next
-# 3.4 - Modify interace to allow use with import
-# 3.5 - Fix for potential problem with PyCrypto
-# 3.6 - Revised to allow use in calibre plugins to eliminate need for duplicate code
+<p>This plugin is meant to decrypt Barnes & Noble ePubs that are protected with Adobe's Adept encryption. It is meant to function without having to install any dependencies... other than having calibre installed, of course. It will still work if you have Python and PyCrypto already installed, but they aren't necessary.</p>

- # Uses shell32.GetCommandLineArgvW to get sys.argv as a list of Unicode
- # strings.
+<p>Upon first installing the plugin (or upgrading from a version earlier than 0.2.0), the plugin will be unconfigured. Until you create at least one B&N key—or migrate your existing key(s)/data from an earlier version of the plugin—the plugin will not function. When unconfigured (no saved keys)... an error message will occur whenever ePubs are imported to calibre. To eliminate the error message, open the plugin's customization dialog and create/import/migrate a key (or disable/uninstall the plugin). You can get to the plugin's customization dialog by opening calibre's Preferences dialog, and clicking Plugins (under the Advanced section). Once in the Plugin Preferences, expand the "File type plugins" section and look for the "Ignoble Epub DeDRM" plugin. Highlight that plugin and click the "Customize plugin" button.</p>
- # Versions 2.x of Python don't support Unicode in sys.argv on
- # Windows, with the underlying Windows API instead replacing multi-byte
- # characters with '?'.
+<p>If you are upgrading from an earlier version of this plugin and have provided your name(s) and credit card number(s) as part of the old plugin's customization string, you will be prompted to migrate this data to the plugin's new, more secure, key storage method when you open the customization dialog for the first time. If you choose NOT to migrate that data, you will be prompted to save that data as a text file in a location of your choosing. Either way, this plugin will no longer be storing names and credit card numbers in plain sight (or anywhere for that matter) on your computer or in calibre. If you don't choose to migrate OR save the data, that data will be lost. You have been warned!!</p>
+<p>Upon configuring for the first time, you may also be asked if you wish to import your existing *.b64 keyfiles (if you use them) to the plugin's new key storage method. The new plugin no longer looks for keyfiles in calibre's configuration directory, so it's highly recommended that you import any existing keyfiles when prompted ... but you <i>always</i> have the ability to import existing keyfiles anytime you might need/want to.</p>

Open a command prompt (terminal) and type "calibre-debug -g" (again without the quotes). Calibre will launch, and you can can add the problem book(s) using the normal gui method. The debug info will be output to the original command prompt (terminal window). Copy the resulting output and paste it into any online help request you make.</p>

DOWNLOAD HIDDEN FILES FROM B&N
------------------------------
-Some content is not downloadable from the B&N website, notably magazines. The Greasemonkey script included in the tools modifies the myNook page of the Barnes and Noble website to show a download button for normally non-downloadable content. This will work until Barnes & Noble changes their website.
