Please upload the file below and use it to check the password against a database of over 14 million passwords. The encrypted hash in John the Ripper is extracted using the utility zip2john. By attacking the hash, you can save thousands of times by entering password information for a zip file into a password prompt. A ZIP2 file, a pkzip file, or a torent can all be converted to a ZIP2.
