Re: OT: how to securely produce a large data file for "one time tape" encryption input

Yes, its XOR rather than "and"... just a reversible process of masking plain chars with random data.
Thanks for the wiki link, it describes the pros, cons and history. FWIW, I intend to destroy the DVD via a microwave oven. That cooks / welds / evaporates the metallic layer in the DVD, so thereby destroying the binary 0 and 1's. Try it, and watch the sparks fly!
Using river or traffic noise for random data is a good idea thanks.
I suppose the random number generation would have to be outside of Windoze to be secure. Ah well...
Just an idea.. why not simply use a dvd with 256 large image files for your random data? Of course to make the key you'd have to read in the file and "process" it a bit before use. When the MIB see your photo collection they will be much less likely to figure it out than if they see, eg, encrypt.dat
