How to set Word password and password cracking method

Office Word documents are the most of the software we use in office, so office security issues have always been our concern, in fact, everything has two sides, can be locked on someone can unlock the problem of knowledge technology. Here are two ways that I can use the Office Word document to set the password for Office Word documents, and to crack down on how office Word is protected.

Password settings for Word files

File Menu Settings

1. Open the Word document that you want to encrypt.

2. Choose "Save As" of "file", appear "Save as" dialog box, select "General Option" in "tool", appear "save" tab.

3, respectively in the "Password to open" and "Password to modify" Enter the password (these two passwords can be the same or different).

4, again confirm "open password" and "Password to modify permissions." Press OK to exit the Save tab. 5, file files.

Set by Tools menu

1. Open the Word document that you want to encrypt.

2. Select the Options command on the Tools menu, and the Options dialog box appears.

3. In the Options dialog box, select the Save tab.

4, respectively, in the "Password to open" and "password to modify" to enter the password, point "OK" exit.

5, save the file.

Second, crack Word file password protection

When using Word for file Protection, we often use form protection (tool-> Protection document), with form protection most thorough, the user cannot edit, also cannot carry on the copy&paste operation, the Word document flaw can let you use the very simple method to remove this password.

1, open Word document, file-Save as-select HTML format, save as an HTML document, open the HTML file with Notepad, search "<w:UnprotectPassword>", you will see the words 5bcecf7a (if the password is 123) )。

2, with UltraEdit or other similar tools to open the original protected Word document, search 7acfce5b, search after, all with 8 0来 replaced, save. At this point the Word document password is emptied, you can cancel the document protection, the password will not be entered, press a carriage return.

Ms has not yet provided a patch for this vulnerability, I think the short-term may not be able to solve the problem, I suggest that future documents do not use this thing to protect. If there is no requirement for the format of the text in the document, the HTML file can be opened directly with IE.
