I am interested in hearing from people out there who have had experience in dealing with data encryption software...ie, software to password protect files on my HD. The caliber of people I am dealing with makes it useless to make the files invisible or to use shareware such as lockout (which can be overridden by inserting a floppy)...I have heard of MacSafe (commerical) and am wondering about it's ease of use and reliability. Also, what happens to your encrypted software if for some reason you forget your password? Is it permanently encrypted? Is there no hope for it? Also, if anyone else has heard of any shareware programs that do this, that would be my first choice, but I have not be able to locate anything shareware that does data encryption. Are there other commericial packages? Thanks for the advice... P.S. I will be using a Mac II so it needs to be compatible. ******************************************************************************* * Greg Ford * * Univeristy of Southern California Internet: gford%nunki.usc.edu@usc.edu * *******************************************************************************

From article <4074@merlin.usc.edu>, by gford@nunki.usc.edu (Gregory Ford): > I am interested in hearing from people out there who have had experience > in dealing with data encryption software...ie, software to password > protect files on my HD. I have purchased PC Tools for the Mac by Central Point Software which has several very useful programs (worth the $). The one in which you would be interested is called PC SECURE. There is an application program and also a DA that does the same. I have used them and they are easy to use. > Is it permanently encrypted? Is there no hope for it? The user is warned to not forget the password . . . > Also, if anyone else has heard of any shareware programs that do this, I have heard (but not used) one called MacPassword which I believe was posted recently to comp.sys.mac.binaries. > that would be my first choice, but I have not be able to locate anything > shareware that does data encryption.

I highly recommend "Sentinel" by Super Mac Technology. It will encrypt file
and / or folders (HFS sensitive) using either DES or a block crypt (your
choice). It also can make the encrypted file invisible. The only trace of
the files that I have been able to see is: If you have a folder that APPEARS
empty, you can check the window bar and (I believe) it will say "21 items"
(whatever's appropriate, etc.) which would tip you off that there IS something
there. But the software implementation of DES is good, as far as I know.
God help you if you forget the "key", Super Mac won't! Nor should they in my
opinion... write it down elsewhere, make it something arcane or whatever, but
if you "forget" the key and can't retrieve your files, then you purchased
GOOD software! If phone support gave you the "trap door" password, what makes
you think they wouldn't give it to a polite albeit malicious user? BTW:
When I say "you" I don't necessary mean YOU!
Lemme know what you come up with.

P.S.: Sorry this is rather bizzare! I had to kill the letter once, and then
use the dead.letter - long story! And to add insult to injury, the mailer
rejected my efforts to e-mail this to you (see header stuff). Mother told me
there would be days like this!
