Protecting whodunnit's novel draft of her zombie romance with a very strong password was a great idea. This is until you can't remember the password to unlock the Microsoft Office document. And now there is no way to enter..
Fortunately, several really useful programs remove password protection from Microsoft Office. Here are five of the best.
Before we begin, let's clear one thing up. You should only use these tools to remove passwords from your own documents. When you use one of these tools on any other document, there is a chance that you are committing a crime. We don't want to have anything to do with it..

If you have a file from an older version of Microsoft Office, there is a good chance that you can remove or extract the password. Unfortunately, those looking to crack passwords in the latest versions of Microsoft Office are almost out of luck.
Supports: Microsoft Word and Excel 95-2003
The Free Word and Excel Password Recovery Wizard is one of the first options to consider. The program tries to unlock files using a dictionary or brute force attack (as most of the other tools on this list do). Attempting to put in a modern Microsoft Office file results in an error.
There are options to configure both types of attacks. The dictionary attack uses different case sizes with the option of a custom word list, while the brute force attack uses variable password length as well as the option of a custom character set.
Supports: Microsoft Word and Excel 95, 97, 2000, XP, 2003, 2007, also claims to be compatible with 2010, 2013
Word Password Recovery Master is another free and useful option to consider for removing and recovering passwords. It is compatible with a wide range of versions of Microsoft Office, making it useful for solving a large number of problems.
The claims of support, however, are not entirely truthful. During my tests, the program was unable to recover or remove basic passwords created with Office 2010, so I have more doubts about its ability to remove encryption in later versions.
However, Microsoft Office 2003 passwords were easy to remove. The program also notes that it does not support custom encryption types, only Microsoft Office's default encryption.
Supports: All versions of Microsoft Office
Elcomsoft Advanced Office Password Recovery (AOPR) is our first professional tool. As such, it comes with a price tag. In this case, you get what you pay for.
At $49, the Home Edition is the cheapest option. However, it doesn't allow the use of GPUs to crack or remove passwords and relies solely on CPU power (and the Home Edition is limited to a single CPU, too).
GPUs are more efficient password crackers, so if you are determined to crack that password; I would suggest upgrading to the $99 Standard Edition.
In addition to price, AOPR has a wide range of features, allowing for custom dictionaries, custom character sets, and variable password lengths, as well as running short pre-brute force dictionary attacks just in case. Also, if you know something about the password you can “mask” information to speed up the process.
AOPR is guaranteed to work on earlier versions of Microsoft Office. The program also successfully unlocked several test documents I ran, though the passwords weren't particularly difficult. Given enough time, AOPR seems like a great option (even if it's expensive if you're just unlocking one file).
Supports: Microsoft Word and Excel 97, 2000, 2003
Figure it! is a slightly older password cracker, originally developed for Windows 95. However, it still works with Windows 10, and better yet, it doesn't require installation, it runs as a simple executable file. It's basic, it only offers a brute force attack, with limited dictionaries as well. But it will work for those basic passwords, in old Microsoft Word and Excel files.
Supports: All versions of Microsoft Office
SmartKey's Office Password Recovery Program is another tool worth paying for if you find yourself in a password protected situation. Like Elcomsoft's AOPR, given enough time, this program will crack an AES-128 key (as long as the key is not that hard). Además, la interfaz de usuario es una de las mejores herramientas de descifrado de contraseñas y es sin duda una de las más fáciles de usar..
La versión estándar te costará $ 24.95 pero no permite la aceleración de GPU. Teniendo eso en cuenta, pagaría $ 34.95 por la versión profesional que permite hasta 32 CPU y ocho GPU.
Claro, hay más programas de descifrado de contraseñas de documentos de Microsoft Office por ahí. La mayoría ofrece la misma funcionalidad que los programas anteriores; Otras opciones de pago cuestan más pero ofrecen la misma gama de características.
