BCWipe for *nix is a bit complicated for novices. AFAIK, it does not automatically do swapoff, mkswap & swapon, so some users will either not wipe their swap device (most likely), or will wipe it and fail to get it working again. My humble WipeSwap script -- all eleven lines of it -- will automatically detect the swap device, turn it off, wipe it, re-create it, and turn it back on for you. Because it's easy to use and safe, more users will be encouraged to clean out that rat's nest of data traces now and then. Also, BCWipe can be dangerous in some hands: a simple typo, and there goes a working disk volume. My scripts are separate and clearly labeled. It's impossible to destroy data with the WipeSwap or WipeFree scripts. Only the WipeAll script will do that, and it's disabled by default. Thus, unless you are at least an experienced user, you will have to read the README to get that one working. Furthermore, my scripts (http://basicsec.org/tools.html) are incredibly simple and totally transparent. Almost anyone can understand what they do. You don't have to take my word for *anything*. OTOH, BCWipe uses a more secure wiping routine, they say. But once you've gone from merely deleting to filling with several passes of random data, there is little more to get out of a software solution, except a false sense of security. The next logical level, really, is physical destruction. Still, there is always room for improvement, and several list members have made excellent suggestions for improving the scripts. I'll be posting updated versions in a few weeks' time, as soon as i get them all tested on enough different systems. chrz, t.
