    "Html": "<p>Well, let's see, that HttpRangeStream thing - I think that might be some sample code that I published a while ago, is that right?&nbsp; I'm pretty sure it's not part of DotNetZip, and it's not something I can support.&nbsp;</p>\r\n<p>But I can offer some ideas.&nbsp; First, I have no idea what the problem might be.&nbsp; The errors that you see suggest that there is corrupted data in your encrypted stream.&nbsp; This may happen if HttpRangeStream is reading the wrong data, or is reading data out of order, and so on.&nbsp;</p>\r\n<p>I have two suggestions for what I would do to diagnose and solve this problem.&nbsp; #1, wrap the HttpRangeStream in a BufferedStream so that it buffers as it reads; this may solve the problem immediately, with no diagnostic effort.&nbsp;&nbsp; If that doesn't work, then #2, I would introduce some tracing or diagnostics directly into HttpRangeStream to see what reads are occurring, and what it is returning.&nbsp; Then compare that to a stream read from a regular filesystem file. (You may find it helpful to create a new stream type, like TracedStream, to wrap around the HttpRangeStream or FileStream.&nbsp; The TracedStream would collect diagnostics on each Read() call, and then pass through the read to the wrapped stream.)</p>\r\n<p>Good luck.</p>\r\n<p>&nbsp;</p>",
