DECZIP - an encoded .ZIP decoder
--------------------------------

As a software developer, I often want to send my customers executable files.
These may be products, updates, fixes or utilities they have requested.

I usually put these in the commonly available and well known ZIP format as it
makes it easier to send multiple files together, and does reduce the size of
the email attachment.

Unfortunately due to the prevalence of malware, most email transporters do
not allow executable files to be attached to an email, and also know the ZIP
format and will scan for executables within them.  Simply renaming the files
does not help, as most of them look at the data within a file to determine if
is one of the disallowed types.

To work around this, I wrote a program to encode .ZIP files to make them and
their content unrecognizable.  Unfortunately .ZIP extractors will also not see
them as valid, which leads to...

DECZIP is a program to decode my encoded .ZIP files. It creates the original
.ZIP file locally on your system.

*** NOTE: If you receive an encrypted .ZIP anywhere other than directly from
DDS/Dave Dunfield, or if for some reason you don't trust what I send to you,
you should NOT run DECZIP to decode the file.

I will send you a file with the type ".Zzz' where the 'x's are any character
from 'A' to 'Z' ("ZIP" is avoided).  To decode it you will need DVM, a free
edition is available on the DDS website:

I use a DVM program because they are not recognized by systems as executable
files.  If this should change, I will update DVM and DECZIP as needed.

Note that currently the free DVM runs under Windows (Win32 or Win64).

You will also need DECZIP.DVM and DECZIP.BAT which are available on the
same site under the name "ZIP decoder".

You must place the supplied .Zxx file as well as the DECZIP.BAT and
DECZIP.DVM files together in a directory, then just double-click DECZIP.BAT
to decode the original .ZIP file into that same directory.

If you do not have DVM in your command path, place DVM.EXE in the same
directory.
