UnlockZip

The service lets users upload encrypted PDF, ZIP, or RAR files and run automated password‑recovery attempts using brute‑force and dictionary techniques. It detects the encryption type, then executes a configurable attack for up to 35 minutes, reporting progress on a status page and emailing results when a password is found.

A small upfront fee (3‑5.9 EUR) initiates the custom attack setup; the final charge is applied only if the password is successfully recovered, reducing financial risk for the user. The platform supports legacy and modern encryption, including AES‑256 for archives, and offers granular control over attack parameters to improve success chances.

Uploaded files and recovered credentials are automatically removed from the servers after the process finishes, aiming to preserve privacy and confidentiality. The tool is positioned as an experimental utility for individuals who have forgotten passwords to protected documents or archives.
