SPac combines both compression and encryption into the
one product and utilizes a user-friendly interface to
make manipulating your secure archives simple.
In addition to compression and encryption, SPac has a
unique, we think, feature that makes it simple to
protect and share sensitive files. Any SPac package
can be converted into a self-extracting archive with a
difference. The difference with SPac over similar
tools is that the recipient of your package does not
require their own copy of SPac. They can add, delete,
and modify files in the package as well as simply
extracting them.

By using SPac your sensitive files need never exist
permanently on disk, while still allowing trusted
friends and associates the ability to modify them.
Once the user has supplied the required password, they
can modify the files simply by double-clicking on
them, the changes will then automatically be encrypted
and stored back in the archive, and the working file
will be wiped from disk.
