Command Line Escape Characters (WinZip)

[Guest sean_walsh]

Hi

 

I have a zip file that is encrypted with a tricky password, which I

need to extract from a .bat file.

 

The password is: -33,33_(}33"33*33=33|33^%33

 

So I try this line in a .bat file:

"c:\program files\winzip\wzunzip.exe" -o -s-33,33_(}33"33*33=33|33^%33

MYZIP.zip C:\MYZIP\

 

This hits a problem because of the double-quote in the password.

"ERROR - missing closing quote on argument"

 

This also doesn't work:

-s"-33,33_(}33""33*33=33|33^%33"

 

I believe the ^ char is an escape character for DOS Command Line

arguments, but that doesn't work. I tried to simplify this by changing

the password temporarily to 33"33 and using the following arguments:

-s33^"33

-s"33^"33"

 

No luck. If I try this:

-s"33""33"

 

It DOES actually get passed, but it comes back with "Skipping xxxx -

the password is incorrect", even though if I use winzip through the

interface, it works.

 

Any ideas?

Some password . . . Try this command:

wzunzip.exe -o -s-33,33_(}33"33*33=33|33^%%33 MYZIP.zip C:\MYZIP\

nope, no luck.

 

There seems to be a few problems: the ^ is a special char, the | is

too, and the " needs to be doubled up somehow.

 

I didnt realise % was too...

 

I tried:

-s-33,33_(}33"33*33=33|33^%%33

-s-33,33_(}33""33*33=33|33^%%33

-s-33,33_(}33"33*33=33^|33^^%%33

-s-33,33_(}33""33*33=33^|33^^%%33

-s-33,33_(}33^"33*33=33^|33^^%%33

 

no luck....

As you have found out, there are several types of "poison" characters in

your password, namely ("|^%. While it may be possible to compose a string

that negates the interpreted meaning of each of them, it would be far more

productive to compose a password that avoids these characters. There are

numerous other special characters on the keyboard such as ~`!@#$*_-+={}[] -

use them instead!

Sean,

Try running this .bat file

 

set mypass=3,3"3|3^3

echo %mypass%

 

Can't find a way to get % in the string though, maybe you can?
