Maybe if we work together, we can crack the code?
Too late, already been done, and unfortunately I thought in google terms and tried to Google the clues, and the result was the second hit.
If you want to keep going then I'll tell you the first thing that I noted was that the numbers before the colon were all hex code - 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10 11 etc.
The second thing is that the alphanumeric codes to me looked like what used to happen at my old work as there was some issues with their network, and occasionally I would get a stream of data when I was browsing that actually came into my sessions from somebody else's browsing. Long story, but if someone were online in a chat room or in a game or something that was not html encoded but something that piggybacked off of the browser and I got their interrupted session, I'd have a screen of results not dissimilar to:
Kx7vy-VBtpYJ PyDg0PjbgxkJ Rd1xXw4alLkJ FeaBmsxfey8J
YsNAjeTGJVEJ leYDU1RuuwIJ jufN-4x1RnAJ IhifTIhRpmoJ
8Maz8upc508J 5dh9_zqVdkIJ xyZftsH8RFsJ L_zmPN_48bMJ
If it helps at all when looking at these in courier font face you'll notice that each is the same length in characters.
If you just want the answer then you can go here, but to be honest I was slightly disappointed.
