Recently I wrote an article explaining how to Password Protect Office 2007 Documents. Because the process is so much different, I felt it necessary to write a separate groovy How-To Article for Password Protecting (and encrypting) Word 2003, Excel 2003, and PowerPoint 2003 documents (yes it’s also possible to add Passwords to Access – however, I’ll write that article shortly). So, just follow the simple step by step process below to quickly Password Protect/Encrypt your Office 2003 Documents (.doc, .xls, .ppt).
Using passwords, you can prevent other people from opening or modifying your Microsoft Office documents, presentations, workbooks and databases. It’s important to note that if done RIGHT, this password protection/encryption process is excellent, which makes it hard to crack. So, let’s get to it.
1. Open the Document you wish to encrypt/password protect
2. Click Tools, then Click Options
3. Click Security tab, and then Click Advanced button
4. Scroll down and Click RC4, Microsoft Enhanced RSA, and AES Cryptographic Provider. By default, the key length is 128, and the box Encrypt document properties is checked. Verify this and Click OK
Please note – It’s crucial to use a strong passphrase or password below.
5. Click in the box Password to open and Type a password. Click OK when finished
6. Renter your Password and Click OK
7. Click File, then Click Save As. (Or, if you have already saved this document, just Click Save, and you’re done.)
8. Type in a Filename and Click Save
Finished! Very Groovy and Secure!!!
- Password to open: By default, this feature uses LAME encryption so be sure to add a long Passphrase along with Enhanced RSA & AES encryption under the Advanced Option.
- Password to modify: This feature does not use any encryption method. It’s designed to collaborate with content reviewers you trust; not to help make your file more secure. It’s a nice way to allow people to VIEW the document but restrict them from making any changes.
- Both passwords: You can assign both passwords. One to access the file and one to allow specific reviewers permission to modify its content. Just be sure each password is different from the other. 🙂
