In the case of cloned
containers, only one copy of a key-block
needs to be saved and hidden; but it is still important to use
as robust a password as possible. Cloned containers are usually
frowned upon when using Scramdisk; because getting the password for
just one will gain access to all the others. SCD makes cloning a
viable, and convenient option; because of the way SCD de-emphasizes
the importance of the password when the key-block is removed.
USING VERY SMALL CONTAINERS.... Small SD containers can be
used as digital envelopes for e-mail and
file transfers; after an exchange of SCD'd key-blocks. It is necessary to reboot your system before attempting to move, or copy, a small (260Kb-4Mb) container if you are running Win95/98 or ME...since even tho' the new information will be intact on disk, when Windows moves or copys one of these newly modified files it will read them not from disk, but from vcache...which will not have the changes in it. The result is that the container, when copied by a move-instruction or a copy/paste, will be either empty or otherwise unchanged at its destination. There are very explicit explanations for this behaviour in Win95/98/ME systems; but they'd glaze your eyes over if I tried to expound on this. Just remember to reboot after altering a small container if you intend to email it, move it, or copy it to another folder on your hard-drive or removable media. This does not affect NT, W2K, or XP systems.
Using SCD as a Scram-Dicer,
or with SCD-Xor, victims of keyloggers who suspect their
passwords are compromised will still have absolute control over access to
their containers as long as the physical locations of the relevant key-blocks
are secure; and if they erase (35-pass) any copies of the key-blocks used in
restorations/removals from their hard-drives. Sami Tolvanens "Eraser" is recommended
for this purpose. SD containers SCD’d and burned
to CD’s may be considered inviolate; until copied to a hard-drive and the
key-block restored with the SCD utility. When it comes time to actually discard an obsolete container, its key-block should be SCD'd, or at the least, SCD-Xor'd with a throwaway key-file before deleting the container. This is especially practical if you have gotten into the habit of using clones. The key-block is the only route an attacker has; so trimming in this way serves a real purpose. |
