thanks for this Tim,
This is the closest so far.
It has a 'work-with' feature that simplifies to an extent the decrypt ->
work-on-file -> encrypt cycle.
I've searched about and as Tim states, the difficult part is the
"stand-alone" part.
Another possible thought is that there are a ton of apps out there,
some freeware, the majority it appears shareware\commercial.
Cryptography is a complex field. It's important that you get much more
than you pay for if you really want freeware security. A false sense
of security is worse than no sense of it at all... you'll keep better
tabs on your jump drive if you know it's wide open.
Many people would consider a password protected zip file encrypted,
and it is, until someone really tries to defeat it that is.

AES Free 2.4: (~.5 meg)
"AES Free is the program that creates self-extracting encrypted
AES-files for Windows. Self-extracting files are executable programs
(EXEs) that contain a AES-file and the software necessary to
decompress the contents. Users can decompress the contents of a
self-extracting AES-files simply by running it like any other program.
No other software is needed. These self-extracting AES-files are ideal
to storage and electronically distribute the information because they
contain multiple compressed files and folders."
"AES Free use AES algorithm and 128 bit keysize. The length of the
password may be up to 7 symbols."
7 characters??? That might be easily be considered as crippleware by
many, but fully functional to a person working in a friendly office.
The number of permutations is plenty high enough that someone isn't
going to sit down and hack out your password over a cup of coffee, if
you use a good one. There are 7^127 possible 7 letter combinations if
I recall stats and 7^250 (or so) possible combinations if you fully
utilize the ascii character set using alt\value combinations.
In an editor, or in a trial passphrase try:
alt\128
alt\171
alt\198
alt\252
Hold your right alt key while pressing a 3 digit number above, then
release the alt key before going to the next. These are valid
characters in PGP passphrases.
Anyway, you might have some luck with this program if you're not a
high powered corporate courier. If you just want to know you're locked
down "pretty good," this might work.
