C# Application Octet Stream

I have an issue with data coming from the internet. I have a package coming from the internet that has the content-type:application/octet-stream.

My question is how do i decode it to readable values (such as 1,4.321,-2.6013 etc)? or is there any application that can do this?

For example:

3ecccccd is 0.400 (http://gregstoll.dyndns.org/~gregstoll/floattohex/) some are real numbers. 07d0 is 2.000

HTTP's Content-Encoding header only applies to how data is encoded inside of the HTTP message itself, not how the data itself is encoded outside of HTTP. There is no Content-Encoding header present in your example, so HTTP is not encoding the data in any way, it is giving you the raw data as-is.

When HTTP's Content-Type header is application/octet-stream, that mean the data (after decoding it based on the Content-Encoding, if any) is raw 8bit data, the sender does not know what the actual type of the data is. Without a more meaningful Content-Type to tell you what the data actually represents, the only thing you can do is analyze the raw data and make educated guesses about what it might be, unless you know through other means what the data is supposed to be.

Usually, binary data formats have a header/signature at the front of the data to identify what the data is, so you might start with that.

Until you can identify the data type, you cannot know which bytes represent what kind of values, what endian is used for multi-byte values, etc. In short, you need more information about the data you are downloading in order to know how to process it.

That content type does not indicate any encoding. All it means is that the data represents a stream of (8-bit) bytes. How they're encoded is an entirely separate matter. To discover the encoding, you can look at other headers (such as Content-Encoding), or else the encoding might be implicit, in which case you'll need to consult documentation. Then choose an appropriate decoding strategy based on that.
