In last few days I noticed many comments complaining about files that UnpackSDC can’t handle. I downloaded one of files that the tool failed to decrypt and it looks MS changed encryption schema again… ;/
The good thing is that I already have original MSDNAA downloader handling new file format so hopefully unpacksdc will be able to deal with it in short time – I just need to take look and analyze if that’s something breakable again 
UPDATE: I didn’t have chance to debug the downloader yet, but from static code analysis looks like Blowfish is in use. I will try to figure out if the encryption key is static once I find some time to run a debugger.

Hi,
Great application just what I need.
Have you had any joy with the new encryption? Will you be releasing the source files for this application?
C’mon problem-solver, what about those schemas? Could it be figured out?
Thank you for informations about new obstacles from MS and for your work about it!
