DEU V 6.60
DEU was originally CEP 1.00, but changed considerably. DEU
actually encrypts files, CEP just renamed the files and hid them
from site. DEU is 100% accurate in both encryption and
decryption, so there is no need to make backups. Look for
other versions within a few days/weeks. I plan to continue
updating this utility. This is SHAREWARE, and the shareware
version can only have 3 letters for a password, REGISTERED can
have up to 15 letters.
USAGE
There is a simple syntax for DEU:
Transforming a file with people around:
C:\>DEU /E /Ffilename.ext
This syntax encrypts filename.ext, password prompt, defualt
method used.
C:\>DEU /D /Ffilename.ext
This syntax decrypts filename.ext, password prompt, defualt
method used.
Transforming a file with password on command line:
C:\>DEU /E /Ppws /Ffilename.ext
This syntax encrypts with password, default method used.
C:\>DEU /D /Ppws /Ffilename.ext
This syntax decrypts with password, default method used.
Trandforming a file with a certain method, (No increase in
size of output file)
C:\>DEU /E /Ppws /M# /Ffilename.ext
This syntax encrypts a file with a certain method,
Replace the # with one of the following numbers,
1,2,3,4,5, or 6. Each number is a different method.
/Ppws can be omitted giving the prompt.
C:\>DEU /D /Ppws /M# /Ffilename.ext
This syntax decrypts a file with a certain method,
Replace the # with one of the following numbers,
1,2,3,4,5, or 6. Each number is a different method.
/Ppws can be ommited giving the prompt.
PASSWORD:
The password can be entered at the command line as shown
above.
OR:
The password is an internal function, brought up
automatically, it can be up to 3 characters long.
(REGISTERED, 15 characters). I was in too much of a hurry
to get this version out that I didn't want to add the
password to the command line, look for it in the next
version.
The Password prompt will look like the following:
Password? ***
* is the echo character used, instead of seeing each letter
you typed, a * will be shown in its place. The backspace
bug has been corrected.
History:
V1.00 -- CEP100.ZIP

rename it. 1 file per directory

Still using Dos's commands but added ability for
5 files in one directory. Also, last version
made.
