great job m8!

It works just fine but it won't decrypt more than 4 files in a row.

I used command line with windows .exe:

LyndaDecryptor /D "K:\Linda Courses\ldc_dl_courses\417082"

and it returns:

K:\Lynda_v1.2>LyndaDecryptor /D "K:\Linda Courses\ldc_dl_courses\417082" [ARGS] Changing mode to Folder decryption! [START] Init Decryptor... [START] Decryptor successful initalized!

then it is hanging, cursor is blinking. on click it aborts

also, you hardcoded "video2brain Desktop App" while it is actually: "Lynda.com Desktop App" C:\Users\AppData\Local\lynda.com\Lynda.com Desktop App which also leads to an error while trying to use /DB option

K:\Lynda_v1.2>LyndaDecryptor /D "K:\Linda Courses\ldc_dl_courses\417082" /db [ARGS] Changing mode to Folder decryption! [START] Init Decryptor... [START] Decryptor successful initalized!

[DB] Creating db connection... [START] Error occured: Could not find a part of the path 'C:\Users\1\AppData\Loc al\lynda.com\video2brain Desktop App'.

I'm also having this issue and still haven't found a solution

DaveLampton commented 8 years ago

@h4ck-rOOt, Thnx for creating this!

I'm having the same problem, in Directory decryption mode it gets through only the first four files then it just hangs. When I try to encode any one of the remaining files using File decryption mode, it immediately exits with the error:

[START] Error occured: Index was outside the bounds of the array.

...followed by the usage instructions.

h4ck-rOOt commented 8 years ago

@plutonian2016 thx man The app was developed to decrypt files downloaded by Video2Brain Desktop App, so i personally don't own a Lynda.com Account or even using the Lynda.com Desktop App.

Feel free to edit the path in Program.cs or combine them to support Lynda.com Desktop App. All you have to do is replacing the hardcoded path on this line with your path. I'm going to support both versions, now that i know the path to this app.

So theres a technique called semaphore i've used to program this app and it seems this is the culprit of all error hanging after 4 files. This issue needs more investigation from my side.

Maybe you can debug this behavior in VS2015?

h4ck-rOOt commented 8 years ago

@DaveLampton just hang in, im going to investigate the strange behavior next week...

mdomnita commented 8 years ago

The binaries available here have the 4 file limit, happened to me too. But when I built the project from Visual Studio community 2015, the built one worked just fine. Probably it was a bug when the binaries available here on github were compiled? Or something changed in Visual Studio since then? Did not follow the timeline, though so I don't know when or where this was changed.

KTsarlz commented 8 years ago

@mdomnita Can you post or link me to a working version? If that's okay with you. I cant really compile the build I dont have vs 2015, only vs 2008

mdomnita commented 8 years ago

There is one in one of the other topics saw it earlier. I can only give you one in the afternoon (6 hrs from now or so).

@mdomnita Yah, saw that one. Tried that one but it didn't worked for me,

mdomnita commented 8 years ago

Then I will build one in the afternoon/evening and post it. I only have all stuff at home and I don't have access to it until then.

KTsarlz commented 8 years ago

@mdomnita Thanks for that! I will be patiently waiting.

mdomnita commented 8 years ago

https://goo.gl/iKiGM2 try this. Just unpack, go to the folder and run LyndaDecryptor.exe /D coursedirectory Works for me.

KTsarlz commented 8 years ago

@mdomnita Tried this on one of the courses I have. It now works!! Thank you! Hope @h4ck-rOOt will make this to work with the master and hopefully will be able to convert .captions to .srt

ZerocoolZa commented 8 years ago

After the code rewrite this issue should be fixed.
