ZIP Key recovers passwords for ZIP archives created with WinZip, PKZIP, or any other ZIP-compatible software. Forgetting a password for an archive created a long time ago is a common annoyance. ZIP Key helps you get your data back. Brute Force, Xieve, Known Plaintext, or Dictionary attacks are used to recover the password. The Brute Force attack is fast, with up to 3,500,000 passwords per second on an average PII system. With a 95 percent recovery rate for English words, the Xieve search yields up to 3,000,000,000 passwords per minute. If at least one file is available unencrypted, a Known Plaintext attack decrypts the whole archive for you, regardless of the password length. A Dictionary attack supports mistypes and additional user dictionaries. SureZip Recovery decrypts most WinZip archives in less than an hour, regardless of the password used to protect it.

Version 6.5 supports advanced AES Encryption for ZIP archives.
