How Do I Crack A Microsoft Word Password
Sofie Kovalcheck
If you're concerned about end-users in your organization losing access to password protected Office files, the DocRecrypt tool might be for you. Note that you have to deploy the DocRecrypt tool BEFORE the file in question is password protected. DocRecrypt can't retroactively recover files that were password protected before you deployed DocRecrypt. For more information see: Remove or reset file passwords using DocRecrypt.
The procedure is standard for most Office applications, so for this example, we will use Microsoft Word 2016.
First, open the Office document you would like to protect. Click the File menu, select the Info tab, and then select the Protect Document button. Click Encrypt with Password.
Select Require a Password to Open the Document, then type the password in the corresponding field. For each keystroke, the password strength meter evaluates your password and indicates the password strength.
I have a password protected Word document that I created myself, have been opening and editing daily. I used it at 9am this morning and it was fine. Then I tried at 4pm today and it tells me the password is incorrect. I have restarted the laptop, emailed the document to myself and tried on two other devices. But it still says the password is incorrect. I am 100% sure the password is right as I have been typing it in daily for weeks.
Do you have Microsoft Word documents with sensitive information? If you have Word files you want to protect, you can easily lock it with a password. You can even mark the file as "Read Only" if you don't want other viewers to make accidental changes. Always use a password you can remember as you won't be able to recover it if it's lost. This wikiHow will show you how to password-protect a Microsoft Word document using your Windows or Mac computer.
NOTE: Do not send an email with the file and the password in the same email. Find some other manner to communicate the password to users other than email if you will be emailing the file.
By default, Microsoft Office 2016* uses AES-256-CBC with 100000 rounds of SHA1 for password verification using a 16 byte salt. AES256 is currently considered the industry standard by many for symmetric encryption. SHA-1 isn't considered a very secure algorithm for password storage since it's a fast algorithm and can be accelerated massively using GPUs. However, since a 100000 iterations are used, this weakness is mitigated to some extent (although it still isn'tanywhere near as good as a dedicated password hashing function like bcrypt/argon2), and if you use a strong password, it shouldn't matter either ways. So the cryptography used by Office 2016 is strong enough to be currently uncrackable provided a sufficiently strong password is used.
Word 2013 and 2016 moved on from the weak ciphers they used in the past when password protecting documents. The problem is that if you're using backward-compatible document files (.doc, instead of .docx), then you're still using the old broken ciphers. There is also a possibility of the data being exposed in temp files or in memory.
As for password managers, Keepass is great. I love it, and it's open source. But I finally moved on to cloud-based password managers because I have three desktop machines (two Windows, 1 Mac), two laptops (Windows, Mac), a smartphone, and an iPad, plus a VMware server running various other server and workstation instances, and syncing my Keepass file(s) between all of the devices where I need access just became a pain in the neck. I researched LastPass, initially, and satisfied myself that they're doing the cryptography right. Later, I checked out 1Password in depth and came to the same conclusion. There are others. I'm not trying to make product endorsements here.
The issue shared by all password-based encryption mechanisms is that they take a strong encryption algorithm (such as AES) and make it far less secure. Instead of requiring a long, complex, and randomly generated encryption key, all an attacker needs is a human-created, often short and simple, encryption password.
The bigger issue, however, is not that passwords are crackable, but that they are shareable. Any legitimate user that you give the document to, along with the password, can share both of those things with an unauthorized party. This could be intentional, in the case of an internal leak, or unintentionally, through social engineering, the storage of the password in an insecure location, etc.
The same applies to the contents of the document itself. If there are no additional editing or copy protection controls, a user with the password can just copy the content to another file or into an email or text chat and share the file that way.
Though as we discussed password-protecting a document in Word will not stop leaks or unauthorized sharing, it can be useful to protect documents before they are opened. Doing so is thankfully quite easy:
If you want to encrypt a Word document for email, you can just password-protect it in Microsoft Word and then send it using any email application such as Outlook, Gmail, etc. However, you also have to find a way of securely transmitting the password to the recipient so they can open the encrypted Word document. This can become cumbersome if you have multiple files to encrypt and send to multiple recipients.
A more secure way of encrypting a Word document for email would be to use PGP encryption (it uses public key technology instead of passwords) and encrypt the Word document as an attachment. Alternatively you can use a dedicated secure email app or service such as Hushmail.
The protection Microsoft Word can provide is not suitable for document sharing in a business environment. It is definitely not suitable for the protection of confidential and sensitive information. Its editing protection is basically useless, and its password encryption is only suitable when the document is in transit or at rest.
All Office files (Office 2016 and above) that you password-protect are encrypted with AES 256-bit. Office 2010 and above uses AES 128-bit. Older versions of Microsoft Office use a proprietary encryption algorithm.
No, you can restrict access and prevent editing, copying and printing by using Microsoft Rights Management Services (RMS). This uses cryptographic keys instead of passwords to protect content. Additional controls such as expiry, and tracking is also available in Azure RMS (the cloud version). However, Microsoft RMS can be bypassed by any user with view access via the use of a simple .exe file published by researchers years ago.
Locklizard does not use passwords to protect Word documents, so there are no passwords for users to share or for tools to remove. We use secure and transparent key management with a licensing system, AES 256-bit encryption, and DRM controls.
IMPORTANT: When setting a password for a document, remember to save the password in a secure location, such as a password vault (TCIT recommends using LastPass for securely storing passwords. Contact the Service Desk to get LastPass)
Microsoft Word's password-protect functionality is designed to prevent edits and modification to templates and other important documents. However, it can be a real pain if you need to edit or change a document and either don't have the password or have forgotten it. Word's password protection isn't very secure, however, and is easily broken with a quick shift in format.
If someone sends you a password-protected Word document, chances are good there's a reason for the lock. Sometimes businesses use them to protect core templates and sometimes they're in place to ensure marketing materials aren't edited before they go live. If you think you should have access to a document but do not, speak with your supervisor or the document creator to find out why.
I have a very weird issue I'm working on. We have some Microsoft Word documents that will randomly apply a password to it when saved. It doesn't happen all the time and I can't pinpoint if there's a specific reason why it happens, but it's becoming a big issue for a client of ours.
I did notice one strange thing. When opening the document (without the password lock) and using Microsoft Word's document inspector tool, the inspector finds custom xml. When this custom XML is removed and then the document is saved and closed, when it's re-opened, the password is applied. Perhaps it has something to do with the custom xml in the documents? Is there any way to view any custom xml in a Microsoft Word document (.doc)??
I caught my husband cheating and he has a Word doc (Office 2016 so docx) that is password protected. I really need to be able to get into that file- anyone know of any software that will help me either remove the password or show what it is? I appreciate your help!
In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array[1] key.[3] Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document.[4]
In Office XP and 2003 an opportunity to use a custom protection algorithm was added.[3] Choosing a non-standard Cryptographic Service Provider allows increasing the key length. Weak passwords can still be recovered quickly even if a custom CSP is on.
In Office 2007, protection was significantly enhanced since a modern protection algorithm named Advanced Encryption Standard was used.[3] At present[when?], there is no software that can break this encryption. With the help of the SHA-1 hash function, the password is stretched into a 128-bit key 50,000 times before opening the document; as a result, the time required to crack it is vastly increased, similar to PBKDF2, scrypt or other KDFs.[citation needed]
Attacks that target the password include dictionary attacks, rule-based attacks, brute-force attacks, mask attacks and statistics-based attacks. Attacks can be sped up through multiple CPUs, also in the cloud, and GPGPU (applicable only to Office 2007-10 documents).[citation needed]
