I have literally never in my life seen any meaningful use case for the OTP after about 1974. It's not part of a sensible discussion. :) On May 4, 2021 4:46:31 PM CDT, vedaal via Gnupg-users wrote: >Or, for the really paranoid ;-)you can have random data on a read-only >mini cdrom,and use it

Modern harddisks don't allow that anymore. Should I assume that "low-level format" in this case means something like dd if=/dev/zero of=/dev/sdX [puts on forensics professional hat] Good question! The tl;dr of it is that the technique to wipe a hard drive will vary according to the kind of
