DeltaSync decompression progress

After quite some time I finally have some code that seems to decompress the message data returned from Windows Live via the DeltaSync protocol. The code is AWFUL, but the results are looking pretty good.

A little further with the decompression routine

I’ve gotten just a little bit further with the decompression code 🙂 X-Message-Delivery: Vj0xLjE7dXM9MDtsPTA7YT0wO0Q9MTtTQ0w9MA== X-Message-Status: n:0 X-SID-PRA: Daniel Parnell <me@danielparnell.com> X-Message-Info: JGTYoYF78jHVrAq/T4xfKLLpTvwPwE0t6g/vyq6tyzbqln5iNnXwcSMg41wQCSulCxd5N8UB57Lq6un/ug7i0YsGX30yo+pm Received: from randymail-a4.g.dreamhost.com ([208.97.132.207]) by bay0-mc8-f11.bay0.hotmail.com with Microsoft SMTPSVC(6.0.3790.2668); Thu, 29 Jan 2009 16:06:38 -0800 Received: from 192-168-1-101.tpgi.com.au (60-241-72-192.static.tpgi.com.au [60.241.72.192]) (using TLSv1 with cipher AES128-SHA (128/128 bits)) (No client certificate requested) by randymail-a4.g.dreamhost.com …

More Windows Live decompression progress

I’ve not had much time recently to work on the decompression routines as family and work need to take priority over side projects…  Last night I picked the code up again and had a bit more of a look.  I found a couple of mistakes in the code I’d written and am now getting a …

Windows Live compression update

I had a bit of time yesturday to spend working on the Windows Live compression reverse engineering.  I successfully decompressed around 20 bytes.  The previous record was 2 bytes 😉  There are two parts to the compression.  First is the compressed data and the second is pointers back into decompressed data.  The compressed data is …

Windows Live Mail

Just a quick note to let everybody know that I’m making good progress reverse engineering the Windows Live Mail protocol.  With the help of a couple of other people I’ve managed to determine the nature of the compression used on the message data.  We’ve successfully managed to build the decompression table and I’m now working …
