About this tool

AES-256 vs legacy ZipCrypto

Old-style ZipCrypto encryption is trivially broken — modern tools crack it in seconds. This tool uses WinZip AES-256, the same encryption WinRAR and 7-Zip use by default. Files encrypted here open in every major archive tool with the right password.

If your password is weak, the encryption can't save you — pick 12+ characters with mixed cases, digits, and symbols.
