Winzip - Forgot Password - Doomed ?

[3MiR]

I've zipped a very important doc.

and I put a password up...

And now...

I forgot my password

I've tried google and I found a bunch of programs that will crack the password but only if they are 4 chars max :S

and this password has 15+ chars.

yeah, I found the programs that could help me, but ask for money.

Is there a way to open my wip without playing money, or am I doomed ?

You could try this one: http://www.goof.com/pcg/marc/fcrackzip.html
But if the password is that long it can take several days to find it.

Do you use numbers or letters, or both and do you use CAPs, do you not know
it is very important

 

[3MiR]

my pass contains only letters, no caps or letter either.

yes it's a long one though.

but about that crack ... I don't have the time to figure it now but if you can please post how to actually use it

Extract fcrackzip.exe to a folder, say C:\zip, copy that passworded zip file in the same folder, then Start/Run C:\zip\fcrackzip.exe <zipfilename>. Here are the options you can use:

O and to crack a 15+ digit password will take over a year with an Intel Pentium 4 HT 3.00 GHz processor so sorry

 

[Lorand]

Yeah, at 15 digits there are approx. 93,795,878,600,000,000,000,000 combinations to verify.
If you want to use such freaking long password, you should memorize it better...
