FAQ GreenForce-Player is a new portable alternative media player, with the function to encrypt video and audio files. http://gfp.rrsoftware.de/index.php?option=com_content&view=category&id=31&Itemid=41 Thu, 04 Dec 2014 00:36:10 +0000 Joomla! 1.5 - Open Source Content Management en-gb How can we make a standalone player with a encrypted file? http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=109:how-can-we-make-a-standalone-player-with-a-encrypted-file&catid=31:general&Itemid=41 http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=109:how-can-we-make-a-standalone-player-with-a-encrypted-file&catid=31:general&Itemid=41 How can we make a standalone player (even if my friend does not have the
green force player and I send him a converted gfp file and give him the
password, he should be able to play the video.) how can I do that?

 

To create a standalone executable file, you just need to check "add player to the media file".
If you use the Player it self to create the protected file you find it under the tab "Others".
If you use the Crypt tool from the SDK you can set it directly in the main window. There you can also set a Icon for the executable. (Encryption documentation)

Where will the password saved? http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=105:where-will-the-password-saved&catid=31:general&Itemid=41 http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=105:where-will-the-password-saved&catid=31:general&Itemid=41
The password will be saved in the settings of the GF-Player (database in the folder: C:\Users\[USER]\AppData\Roaming\GF-Player\data.sqlite) on your computer and will be not copied with every GFP file.
So it will be asked at every PC(User on a computer).

The passwords are also encrypted with a dynamic password created of the computer hardware.
So it's secure, if any one copies the settings file, so he can't play it on his computer!

How effectively does the option “Disallow Snapshots” protect the media from creating screenshots? http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=57:how-effectively-does-the-option-disallow-snapshots-protect-the-media-from-creating-screenshots&catid=31:general&Itemid=41 http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=57:how-effectively-does-the-option-disallow-snapshots-protect-the-media-from-creating-screenshots&catid=31:general&Itemid=41 The security depends on the option which is selected.
If the option “Active” (default is “Inactive” option) is used then there is only a weak
protection. Hotkeys like print, print+ CTRL, print + ALT will not work.
If the option “Extended” then it will be harder to create screenshots of the media. Although
it will be still possible. Media files will not be displayed if mirror drivers are active. Also it will
protect against desktop screenshots (only for Windows Vista / 7). If this option is used it will
also disable the DWM of Windows while the player is running.

How to install the GreenForce-Player? http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=56:how-to-install-the-greenforce-player&catid=31:general&Itemid=41 http://gfp.rrsoftware.de/index.php?option=com_content&view=article&id=56:how-to-install-the-greenforce-player&catid=31:general&Itemid=41 The GreenForce-Player does not need an installation. It requires only the GreenForce-Player.exe.
Therefore it is ideal for use on a portable media like an USB stick.
The file extension “.gfp” will be registered automatically at the first start of the application.
There is also an Installer available which will create additional entries in the program menu and on the desktop.

For the password you can set a tip/hint to help you to remember your password. You can also set tags and a cover (.bmp, .jpg, .jp2, .png, .tga and .tiff) for your protected media file. If you want to protect the media against snapshots you can use the option “Disallow snapshots”. Choose “active” for a weak protection or “extended” for an advanced protection.
