• New environment variable %KIXCRYPTDEBUG% set to "1" if the package was made with the "-d" debug flag.
• New environment variable %KIXCRYPTEXE% which is the full path to the package name when started. This is also quite experimental, so let me know your findings.
• %COMSPEC% is no longer included in the default execution command.
• "-x" experimental script protection

VERY IMPORTANT 2
There is a problem with environment variables being expanded when starting the unencrypted script under the control of a command interpreter. To avoid this issue, either:
1) Don't use environment variables in your script or disguise them so that they don't appear as %ENVVAR%.
2) Don't use %COMSPEC% (command.com or cmd.exe) in your execution (-e) string. The default command no longer includes %COMSPEC%.
If you don't use the "-x" switch KiXcrypt works as it always has (or at least it should let me know about any regressions)

For those of you interested in how it works, the "-x" option writes a boot script rather than the encrypted script. The encrypted script is passed as command line variables, which are then catenated in memory to form the original script. This is then Executed().

If you create the package with the debug option the recreated script is saved as "bsdebug.kix" so you can compare it with the original script if there are problems.

Note, if you have a very large script you may get problems with environment space.

To save you hacking it, here is the boot script:

code:

---

Break OFF
$KIXCRYPTCOUNT=0
$KIXCRYPTLINES='Exit 1'
While Execute('Exit IsDeclared($$sKIXCRYPT$KIXCRYPTCOUNT)')
	Redim Preserve $KIXCRYPTLINES[$KIXCRYPTCOUNT]
	$KIXCRYPTNULL=Execute('$$KIXCRYPTLINES[$KIXCRYPTCOUNT]=$$sKIXCRYPT$KIXCRYPTCOUNT')
	If $KIXCRYPTLINES[$KIXCRYPTCOUNT]='0' $KIXCRYPTLINES[$KIXCRYPTCOUNT]='' EndIf
	$KIXCRYPTCOUNT=$KIXCRYPTCOUNT+1
Loop
If %KIXCRYPTDEBUG%
	$KIXCRYPTNULL=RedirectOutput('bsdebug.kix',1)
	Join($KIXCRYPTLINES,@CRLF)
	$KIXCRYPTNULL=RedirectOutput('')
EndIf
Exit Execute(Join($KIXCRYPTLINES,@CRLF))

For instance, using "CMD", "COMMAND" or "%COMSPEC%" will generate a console.

yet again, is there a way to make this standalone?
if not, think I need to go back to simple sfx stuff

How good is the encryption?
Hmm. The encryption itself is quite good because it is proprietary. Only I know how it works and I'm not telling. It is good because without knowing how it works it is hard to get started cracking it.

I'd love to be in a position to get peer review of the code and techniques, but even giving hints would lessen the effectiveness of the encryption, so I can't divulge anything. Sorry

is not true.
if you haven't created a console beforehand, all these do NOT create a console.

Yes, and no The point about this comment is that using "wkixcrpt.exe" will not stop a console being created. It will not create one itself but if by your actions one is created then it will appear. Some ways of doing this:

• Use "kix32.exe" or another console application.
• Use "wkix32.exe", but forget the "/i" switch.
• Use "%COMSPEC%" in the execution (-e) command

code:

---

wkixcrpt -e "%COMSPEC% /C wkix32.exe /i %KIXCRYPTFILE%" "myscript.exe"

the usage switch at least does not work

how do I make reliable soft if kixcrypt crashes on existing file?
