Re: How do I know if its encrypted?

If you want to not be able to read the files on your storage site, then why not just try reading them? Check their entropy to make sure it is maximal, check that they can't be unzipped, unstuffed, displayed as gif or jpeg files. When a new format becomes popular add that to the list. This is all you can do. What does this gain you? I'm not sure. If someone posts encrypted Windows 95, then publicizes the location and the key, people will get the data just as easily as if it were not encrypted. Hal
