Self Decrypting Archives

Because you can't make a vendor install a piece of software, free, licensed,
unlicensed, etc . They just won't do it. Also, most of the people I'm
dealing with are not in the least technically inclined.
Spreadsheets is programmin' to them. (I cringe when I think about someone
asking me to "program an excel file" for them. --- I'm gonna need lots of
therapy---just look at my eye twitch.) You know the ones who take classes
to be 'certified' to send and receive e-mail, then proudly hang the
certificates of completion next to their college diploma. (TWITCH
TWITCH--- It's getting worse).
So, SDA's have saved my bacon on more than one occasion. I have recently
started using GPG because it lets me call it remotely from an FTP script on
the local host. This way I can use JCL (batch to you DOS types) and run my
file transfers from the master scheduler. This is fine when the recipient
can receive encrypted e-mail attachments, or FTP. But the few that need
LOTS of hand holding to open an e-mail attachment are the ones who give me
the most headaches, and are also the ones who won't install software.

I'm curious why installing GnuPG isn't a viable option. (I assume
this is a Windows platform). I certainly understand the resistance to
install a new program under Windows, but given the use you are talking
about (regular symmetric encryption of a file) GnuPG doesn't need to
be "installed" to be used. Just unzip the archive and you can run the
'gpg' program. No installation necessary, and to "uninstall" just
throw the program in the trash.
If you really wanted to, you could even send your receiver a zip file
containing the "gpg" binary, plus the encrypted file, and a batch file
that contained something like "gpg theencryptedfile.gpg". Poof:
instant SDA. Of course, it's still insecure ;)
