WINZip Password

[hunnich]

Recently I tried to open a document that I Zipped with WINZip but I forgot the password for it. Is there any way that I can open it without the password? Its an important document and I really need to get it open.

you can get tools to brute for the passy but that cant take along time (longer the passy the longer it takes)

you not have no winzipped copy??

Izarc (search google for your best mirror, I don't want to overload one), can brute-force a zip password (with character range limits if you are sure you used, say, only lowercase alpha).

Even WITH limits, it's still painfully slow, as each additional character means an exponential increase in combinations.
If the password is vulnerable to dictionary attack, then that's another way.

Other password crackers can use a better technique, the "known plaintext attack" if you have an identical copy of any file in the archive.

If I'm not mistaken latest version of Izarc has excluded the zip password module, for rather obscure reasons...
