Modern versions of Excel (2013 and later) utilize 128-bit AES (Advanced Encryption Standard) encryption for passwords that protect the entire workbook from opening. There is a common misconception that software can "crack" these passwords instantly. In reality, true AES encryption is mathematically unbreakable via brute force in a reasonable timeframe. LostMyPass, like other recovery tools, does not "break" encryption. Instead, it employs a combination of (trying every possible combination of characters), Dictionary attacks (using a pre-defined list of common words), and Mask attacks (where the user remembers part of the password, such as length or specific letters). LostMyPass distinguishes itself by optimizing these attack vectors for Excel’s specific hashing algorithm, significantly reducing the time required compared to generic password crackers. : If you remember specific details like length
The software doesn’t just guess randomly. It offers: like other recovery tools
