Can you crack a ZIP file password?

Forgot password of oen ZIP is it possible to crack zip files or is it a fairy tale?

 

[lucky.sparks]

brute force and dictionary attacks, nothing good if "you" were creative with your password and/or used symbols or random strings

I got around 50 passwords, they're all 10+ letters, and have at least one uppercase letter and at least one special character, but I tried all of them which means I've made a new version of some of my passwords and can't remember it.. Doesn't helps that they're all on serbian or russian language for met remember them more easily so I ran a dictionary of words thru John to try to crack it but didn't work...

check if you haven't placed an accidental space somewhere.

or if you have a pattern of how you make your passwords, perhaps you can guess your password.

but yeah, this sucks, once I had put disk encryption password on a server that didn't go out for a year, and then one day it rebooted. Took me an hour of pure panic to remember it.

Very possible and there actually alot of tools out there already that do it for you for free as long as the pw isnt ridiculously complex

I have 20 solana wallets this is the 20th one's seed I store them all on old HDD that I plug in only when I need those seed phrases and there's airdrop that gives me 500$ for each of those 20 wallets and i just can't fathom password that i used for 5 of the wallets, rip 2,5k :sob: :skull:

I tried the John tool, but my password is surely 10+ letters, one uppercase, one special character and is not on English but rather either Russian or Serbian

I am damn sure there might be some tools who can do that, you need to do digging to find working tool.

I always had luck with a program called Password Recovery Bundle 2012 that I have on an old Laptop running Windows 7.

Short answer is no. ZIP files are encrypted with AES-256.

The key that you're looking for is derived from that AES-256 encryption, by using a mathematical function called "slow-KDF".

The problem is that AES-256 is uncrackable with our current theories of physics.

There are too many calculations to be done! You're required to test all 2^56 possible keys to make sure you find the correct one.

Dude! 2ˆ56 is an obscene ridiculously large number! Our brain can't even understand that order of magnitude.

Insert it into Wolfram Alpha. It's 115 followed by 78 zeros! There's no fckng way on this earth to bruteforce this, no matter how sophisticated a dictionary attack is. Not even quantum computers can solve it.

Sorry, but, you either come up with a whole new understanding of the laws of physics, or you should forget about this zip file!

I doubt cracking a password for a zip/RAR file is doable unless it's a dictionary brute force method, but it depends on the complexity of the password. It may take from 1 day to 30 years or more to crack

I'd say to just say bye bye to that file.

Doable.

Plaintext attacks are your best best.
There are a lot of known vulnerabilities in the way Zip files are encrypted. No need to bruteforce anything.

I have a ZIP file that is locked with a password. Can you open it? I am willing to pay $150 for the password.
