Full seller details: Legal information.
Point it at the .zip you locked and cannot open, let dictionary and mask search do the work on your own machine, and get a plain unpacked archive back.
The archive is yours, the password is gone
You zipped something months ago, set a password, and now the archive will not open because you do not remember it. Online services offer to help, but only if you hand your private archive to a server you do not control. This runs on your own Windows PC, never sends the file anywhere, and works through the password with dictionary and mask search.
How to use it
Add your archives
Drag in a single .zip or a whole folder of them. The tool reads each archive, detects how it is protected, and pulls out what it needs to test passwords - the files inside stay untouched.
Choose how to search
Start with a dictionary of common and likely passwords, or set a mask when you remember the length or part of it - a prefix you used, a suffix, digits on the end. A narrower mask finishes far sooner.
Get a clean archive
When the password is confirmed, save a plain unpacked copy of the archive to a folder you choose. No password prompt, no re-zipping, just your files.
Benefits
WinZip AES is weaker than it looks
Modern .zip archives use AES, but the key is derived with only 1000 PBKDF2 iterations - roughly 100 times fewer than Office 2013 and later. That gap is why a dictionary run and short masks actually finish on a ZIP, where the same attempt on a Word file would not.
Old ZipCrypto barely resists at all
Archives made with the traditional PKWARE ZipCrypto scheme have no key derivation step, so passwords are tested by the billion per second. If your archive predates AES protection, recovery is usually quick.
A whole folder in one run
Load many .zip files at once and let the queue work through them unattended. You get a plain unpacked archive out of each one that opens, all on your own PC.
Why people use it
GPU acceleration
A graphics card tests millions of passwords a second, which is what makes dictionary and mask runs practical. Without a GPU it still runs on the CPU, only slower, and warns you up front how long it may take.
Everything stays offline
The archive is opened and processed on your own Windows machine. Nothing is uploaded, no account is needed, and the file you are trying to open never leaves the computer.
Two protection types, handled
It recognizes both WinZip AES and traditional ZipCrypto, extracts the right kind of hash, and searches accordingly - you do not have to know which one your archive uses.
