My code will track what parts of the DVD have been used, to ensure its not reused. Didn't think I needed to mention that.
I thought you should have known, as Greg explicitly asked you about it:
Are you providing the same blob of random data to all users?
As I said, I am not an expert. Greg, perhaps you misunderstand my intent; I want my conversations with my wife back home to be private; I want to show the data collectors the digitus impudicus on principle.
As Greg says, if you were to roll out your own encryption method then you'd fail at this.
That said, if you create a true OTP and use it properly (including destroying it properly), then there's no issue here. But OTP's aren't very popular in part because they're so cumbersome to use.
if its protection through obscurity then fine, its intended use is for me only.
Sounds like a rather dangerous attitude. But hey, it is your data after all.
All I asked for, was a way to produce random numbers where there is no chance of Windoze uploading copies. Useful suggestions were given, thanks.
Cheerio,

Alas, this is not enough. http://www.wired.com/2015/03/researchers-uncover-way-hack-bios-undermine-secure-operating-systems/
