Which Office Files Qualify for Guaranteed Recovery?
Guaranteed Recovery
- Word 97-2003 (.doc)
- Excel 97-2003 (.xls)
- PowerPoint 97-2003 (.ppt)
- 40-bit RC4 encryption
Deep Recovery
- Office 2007+ (.docx, .xlsx, .pptx)
- 128-bit key encryption
- AES-128 / AES-256
- Password hints improve success
How Do I Know If My File Qualifies?
You do not need to know! Simply upload your file and our system detects the encryption type automatically within seconds.
As a general rule, if your file has a .doc, .xls, or .ppt extension and was created before 2007, it very likely uses 40-bit encryption and qualifies for guaranteed recovery.
Common scenarios where old Office files are found:
Why Basic Password-Removal Utilities Hit a Wall
Basic online utilities can only remove editing or formatting protection - the kind that restricts changing cells in Excel or editing a Word document. These workflows cannot handle open passwords.
If your file requires a password to open, the content is encrypted and needs actual key recovery - not simple protection removal.
Our approach is fundamentally different. We do not guess your password. For Office 97-2003 files, we break the 40-bit encryption key directly by testing all possible keys until we find the right one. That is why the success rate is 100%, regardless of password length or complexity.
