I have been told that Windows XP can have its virtual memory turned off
- but I figure it would be rather hungry for RAM.
I wonder if the entire crypto, floppy reading and writing, text reading
and writing code could be put on a floppy? Maybe a small Linux
installation with one well chosen cryptography algorithm. Then it could
be run on any PC with a floppy, without involving nework cards or a hard
drive. The program might be made constitutionally incapable of storing
the plaintext to the floppy or anywhere else - though it would be good
to read from a text file on floppy when creating the plaintext file.
Maybe create the keys elsewhere - on a Windows or Linux PC. These would
be written to the floppy. Perhaps a single program could generate the
keys and write the entire floppy.
The idea would be to boot from this floppy, decipher the encrypted file,
which could be on that floppy or read from another one, view or edit the
file and then encrypt it again if it had been changed. The user would
need to store the encrypted file on other floppies for safekeeping.
A Linux kernel with no TCP/IP or hard disk stuff might be pretty small -
and I imagine the cryptography code wouldn't be too large.
