I have a question regarding the ideas which have been circulating about using CD ROMs as key storage. How does one go about rapidly and effectively erasing everything on a CD ROM? The reason I ask is, in the case of OTPs you want to cancel your key as it's used, to prevent accidental double-use of key; and of course in any system you want to make sure that all your crypto material can be wiped squeaky clean in the event of a barbarian invasion.

A lab proven method: Take CD-ROM. Place in standard kitchen microwave. Set on high power cook for 5 seconds. Press start. Watch the action. Hang resulting artifact on wall as curiosity, which is all it's good for now. Let the wave air out a little (this won't fry it). A great way of trashing obsolete but confidential CD's, and perhaps the cypherpunk equivalent of flushing the dope stash. Tim O.
