honestly, ron, i don't know at this point. i have an old backup of the
files, copied to cd before i encrypted them (what a brilliant idea the
latter has turned out to be -- argh!). i think those older versions are what
i'll have to default to. i'm running into brick wall after brick wall re
decryption, even though i'm almost certain the cert/key combo i've recovered
is the correct version for the files. in fact, it has to be; they are the
only files i've ever encrypted on this machine.
i've tried re-establishing a user account with the same name as when i
encrypted the files, then importing the cert/key combo into that account
(with full admin privileges). that doesn't work any better than importing
the cert/key combo into my current user account (with a different name) or
even a direct admin account approach. that said, is there a private or
public key (or some other security block) set up unique to each account,
such that even though i've recovered the cert/key combo from my previous
account i still can't use it for anything?
man, these bricks are hard.
