如何找到并播放由Lynda.com的Android或Windows应用程序下载的视频 [英] How to find and play videos downloaded by Lynda.com Android or Windows app
问题描述
有是一个应用程序，这些特征通过他们的Android和Windows应用程序下载他们的视频进行离线观看。我想知道，这是否应用程序将保存这些视频，如果他们被加密，如何解密并播放它们？
我是一个程序员，但我对此事一无所知的Android / Windows应用程序的开发，这里是我已经能够到目前为止破解：
在Android
现在看来似乎把视频保存在：/storage/emulated/0/Android/data/com..android.root/files/videos//encrypted/
这些文件没有扩展名，我把它们复制到我的笔记本电脑，并试图给出不同的流行媒体扩展，什么都没有WMP，VLC和放大器至今工作; Quicktime播放器。
我试图找出使用论坛报文件类型（在此链接指定： http://goo.gl/EU99G3 ）这个实用程序将推荐它的MP3文件（当它应该是一个视频），我改变了扩展，MP3，它没有任何工作。
我试图打开在ISO克星和其他几个应用程序的文件。最后，尝试当我选择来计算检查选项不同的事情，Android系统本身，它显示一些MD5和SHA-1的值。我没有太多熟悉这些术语，但是想通了，这些文件似乎是加密
如果我尝试直接打开Android上的这个文件，系统开始产生十六进制转储，然后资源管理器崩溃。
现在，如果这些文件是真的视频文件是加密的，是有办法，我才能解密，并直接在视频播放器中播放？
在Windows商店App在我的笔记本电脑的视窗8.1
我发现应用程序的文件存储在：
C：\\ Program Files文件\\ WindowsApps \\ .com..com_1.5.0.2_neutral_split.scale-140 _
C：\\ Program Files文件\\ WindowsApps \\ .com..com_1.5.0.2_x64 __
C：\\ Program Files文件\\ WindowsApps \\ .com..com_2015.924.1324.2728_neutral_〜_
我能弄清楚如何分配给当前登录用户的权限，并获得访问这些路径到达，但不能作任何进一步的进展都发现在这些文件夹加密和非加密的视频文件。
我明白，如果我真的只是想要下载的视频文件有很多更好的和容易的方式直接登录他们的网站，并使用任何视频采集应用程序或扩展，它一样容易了，这确实的作品。
但在这里我的本意不是要下载的视频，而是我只是好奇，做自我学习和探究事物的道德黑客。只是想了解，是否甚至可以解密，找到适当延长，并直接播放这些没有应用程序或没有。而哪里Android和Windows应用程序都被实际存储我自己的设备上这些影片对此我无法访问/播放无需应用..呵呵做得好应用程序开发者！
任何帮助或指针AP preciated。感谢：）
我想知道同样的事情，我做了一些探索与windirstat，发现了一大捆文件时间：
<$p$p><$c$c>C:\\Users\\*username*\\AppData\\Local\\Packages\\lynda.com.lynda.com_0dmhem0sv94sr\\LocalState\\offline\\194074他们是.file，但路数是视频和他们玩VLC罚款。很可能浪费时间与他们并添加.AVI或什么的，到最后的完整性，如果你想..
There is an App which features downloading their videos for offline viewing via their Android and Windows app. I was wondering where does this app saves these videos and if they are encrypted, how to decrypt and play them? I am a programmer but I know nothing about Android/windows app development, here is what I have been able to hack so far:
On Android
It seems like it save videos at: /storage/emulated/0/Android/data/com..android.root/files/videos//encrypted/ These files have no extension, I copied them to my laptop and tried giving different popular media extensions, nothing worked so far in neither of WMP, VLC & Quicktime Player. I tried to identify file type using TrID (as specified in this link: http://goo.gl/EU99G3) and this utility suggests its an mp3 file (while it should be a video), I changed the extension to mp3, it did not worked either. I tried opening the file in ISO buster and several other apps. Finally while trying different things, on android system itself when I choose the option to compute checks, it display some MD5 and SHA-1 values. I am not much familiar with these terms but figured out, these files seems to be encrypted If I try to directly open this file on Android, System starts generating Hex Dump and then file explorer crashes. Now if these files are really the video files and are encrypted, is there a way I can decrypt them and play directly in a video player?
On windows store App in my laptop's Windows 8.1
I found App files are stored at:
C:\Program Files\WindowsApps\.com..com_1.5.0.2_neutral_split.scale-140_
C:\Program Files\WindowsApps\.com..com_1.5.0.2_x64__
C:\Program Files\WindowsApps\.com..com_2015.924.1324.2728_neutral_~_
I was able to figure out how to assign privileges to currently logged in User and gain the access to reach at these paths but couldn't make any further progress to find encrypted or non-encrypted video files in these folders at all.
I understand that if I really just want to download the video files there is much better and easy way by directly log in to their website and use any video grabber application or extension, its as easy as that, which does works.
But my intention here is not to download videos but rather I am just curious to do ethical hack for self learning and exploring things. Just want to understand whether it is even possible to decrypt, find appropriate extension and play them directly without the app or not. And where does both Android and Windows Apps are actually storing these videos on my own device which I am unable to access/play without App.. huh well done app developers!
Any help or pointers appreciated. Thanks :)
I was wondering the same thing and I done some exploring with windirstat and found a large bunch of files at:
C:\Users\*username*\AppData\Local\Packages\lynda.com.lynda.com_0dmhem0sv94sr\LocalState\offline\194074
They are .file but the large ones are the videos and they play fine in vlc. Could probably mess around with them and add the .avi or whatever, to the end for completeness if you wanted..
