How to Crack Excel Password without Any Software?

Password protection is one of main features of MS Excel which allows user to protect their confidential data from unauthorized access. There are two types of passwords which can be added to an excel file: "Password to Open" and "Password to Modify" (or edit excel sheet). Many times excel user forget their own password and hence loses access to their important (and confidential) data. To help such users I am writing about how to remove "Password to Modify" excel sheet without any software.
  1. Change the file extension of excel file from xlsx (or xls) to zip.

  2. Right click on the zip file and extract the content of this zip file.

  3. In extracted zip folder navigate to location xl->worksheets and right click on the password protected xml sheet.
  4. Open this sheet with Notepad and then search for the tag “sheetProtection”.

  5. Once you find the “sheetProtection” tag then you need to delete this tag and save the file.

  6. Now replace the old xml file (in zip archive) with this edited xml file. (You can also replace complete xl folder simply by dragging it to zip archive).
  7. Now change the zip archive extension from zip to xlsx and open the file.

Now you can edit the excel sheet without any password.
Note: - (a) Always make a backup copy of original excel file to avoid any accidental loss of data.
(b) This method works only with MS Excel 2007 and 2010.
(c) This method does not work to unprotect excel sheet if it is protected with “Password to Open” excel file. In such situation you can use excel password recovery software to open password protected excel file.
I hope that by following the above mentioned steps you can easily remove password of your encrypted excel sheet.

How to manage security settings of outlook PST file?

Almost every outlook user is aware that email items such as emails, contacts, calendars, notes get stored in a PST file format in Outlook. These PST files also stores important and confidential information of user so it is very necessary to maintain the proper security of PST file. When an outlook user creates a new PST file then MS outlook offers him to choose from three types of encryption:
No Encryption–When you enable this thenthere is no encryption on Outlook PST file (as the name suggest). Anyone can access your PST file by using a text editor so it is always better to avoid this encryption setting.
Compressible Encryption - If you use compressible encryption then your PST file is encoded in format which can be compressed by using compression programs. If a PST file has compressible encryption then it can not be read by any text editor.
Higher Encryption - This type of encryption settings ensure highest degree of protection. High encryption enabled PSTfiles can also be compressed but degree of compression is less as compared with 'Compressible Encryption'. It also increases time to fetch data from a PST file having Higher Encryption setting.
If your PST file does not contain confidential information then you can use 'Compressible Encryption' (or even No Encryption) otherwise you should always select "Higher Encryption".
Beside these securities setting you can also enable password on outlook PST file. Enabling password on PST file ensures that no unauthorized user can access it irrespective of the security settings (compressible or Higher Encryption). The only thing which needs to take care is that you should well memorize your password so that you never forget it. In case you forget PST file password then no need to worry because you can use outlook password recovery software to recover password of PST file.
I hope after reading this article you will be able to protect your private and confidential outlook data from unauthorized access.
