Recovering password from WinZip

[bojan]

I forgot the password of the encrypted Winzip archive... and now I am at the mercy of overpriced web rescuers... or not?

I have one non-enctryted file (jpg) that is also inside the archive, and I tried to use one of the plaintext-attack capable demo applications... but it can't find the file for some reason (becaiuse it is not in the root directory?).

Does someone know about simple app that will extract the password from that archive?

try method 2 on this page. least nsis is legit and will compile your zip into an exe and will bypass the password apparently

bugger.

jog your memory.
Look at the file's creation date.
Then go through your password manager equivalent and find one that was created around the same time.

At least, Winzip won't lock you out after 3 tries, right?

Memory, eh...
I came up with couple of dozens of possible passwords when trying to use ZIPCracker. Nothing worked... I really protected that file ;)
I remember at that time I was for some reason pressed to change the password, and the od one dissapeared into oblivion.

Brute force attack is probably not practical because I think there may be 8-12 characters in that password. It will take time to crack it...
Anyway, thank you all for your help.

Kali linux has tools for dictionary and brute force attacks on zips. download the LiveCD, burn to disc and boot from it on a spare machine plug in a thumbdrive with your zip file, let the machine do the work. Some tools let you wildcard your brute force attempts to save time in case you know something about the password. Kali is free. Dictionary attacks are hugely fast even with variation options compared to bruteforce. Some files have tools that use some exploit to remove passwords (PDFs are easy to remove protection). Kali is a great toolbox but not for computer newbs, though there are heaps of youtube and web tutorials for using kali on particular files. Its an all freeware tools Distroso you're not getting cracked "warez" files, I use it for penetration testing to secure networks rather than on files.
