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.

Unprotect Excel Sheet with Brute-Force Attack and Masking Technique

-->

MS Excel provide many features to manage and analyze large volume of data. Graphical representation tools and inbuilt (mathematical, financial, statistical and logical) functions make it very easy for everyone to analyze and summarize data without any special expertise. Besides so many user friendly features, MS Excel also provides a very useful security feature called “Password Protection” to prevent unauthorized access (or modification) of valuable data. This password protection feature of MS Excel allows User to protect entire workbook, individual sheet or cells of a file. 

Many times it happens that Excel user forget the password enabled by them to protect their worksheet. In such situation it is really very difficult to unprotect excel sheet without password remover software. I searched a lot to find methods of removing excel password without software but did not get even a single method which can do this. From my search I analysed that almost all the excel password remover software are based on two features: Brute-Force Attack Technique and Masking Technique.

Let me explain you how Brute-Force Attack and Masking Technique help to unprotect excel sheet. 

Brute-Force Attack Technique – This technique involves making all possible permutations of characters (lower case letters, upper case letters, special characters, numbers) of your password. All excel password breaker software provides you the option to specify the probable length and characters in your password. On the basis of the password length and characters all possible permutations are made and run through for checking. Total time taken by software to recover excel password directly depends on the total number of permutations (which in turn depends on the length and complexity of your password). 

For example if your password is 3 characters long and include numbers, Upper case and lower case letters then there will be total 62 * 62 * 62 = 238328 guesses or permutations (Here 62 = 26 lower case letters +26 upper case letters + 10 numbers).

Masking Technique – Many time it happens that user remember first few (or any) characters of their password but not able to recall full password. In such situation Masking Technique allows user to specify the initial (remember) characters and replace the unknown characters by '?'. This helps Brute-Force process to search for the unknown characters only and hence reduces the time to crack excel password. 

Overall we can say that because of Brute-Force Attack and Masking Technique excel password remover software has very high success rate. So, if you forget your excel file password then you can use any excel password recovery software based on Brute-Force Attack and Masking Technique.

How to Solve the Problem “Outlook keeps asking for password”?

Many Outlook users complain that Outlook keeps asking for password (network password) repeatedly. Situation becomes worse when “Enter Network Password” pop-up message appears after every 20-30 seconds. Pop-up keeps on flashing even the user has entered correct username and password. Enabling the “Save Password” or “Remember Password” also does not solve the problem.

The possible reason for this problem can be:

• Corrupted Outlook profile.
• Registry has incorrect Protected Storage System information.

Solving corrupted Outlook profile problem:

This problem can be solved by creating a new outlook profile and connecting this profile to the .pst file of old profile (or damaged profile).

1. Create new outlook profile.
2. Locate the .pst file used by damaged profile (you can find it at location C:\Documents and Settings\ user_name \Local Settings\Application Data\Microsoft\Outlook\Personal Folders.pst).
3. Configure new profile to use .pst file of old profile. This can be done by following the given below steps (based on MS Outlook 2010):

1. Open Outlook.
2. File tab -> Info -> click Account Settings (in Outlook 2007 Account Settings option is available in Tool menu, in Outlook 2003 and 2002 Tool -> Options).
3. E-mail tab-> click your email account. (in Outlook 2003 and 2002 Mail Setup -> Email Accounts -> View or change existing e-mail accounts - > Next)
4. In the "Account Settings" dialog box Click "Change Folder".
5. Click New Outlook Data File-> click Office Outlook Personal Folders File-> click OK.
6. Browse and locate the .pst file of old profile-> click OK.

Solving Incorrect Registry information Problem:

1. Close all the programs
2. Click Start -> Run
3. Enter "Regedit" and Click "Ok"
4. Locate the folder : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
5. Edit Menu-> New-> Expandable String Value
6. Name it as "AppData"
7. Double click new entry and write "%USERPROFILE%\Application Data" in "Value data field" box.
8. Click "OK" and Close the registry editor.

Note: Before following this solution make sure that you have created a backup copy of registry.

I hope that with the help of these two methods you can make outlook to remember your mail password. So no more complaints that Outlook keeps asking for password.

How to Unlock password-protected Email Account

Outlook Express (Photo credit: Wikipedia)

Each one of us wants to keep our vital data safe and protected, whether it is data stored on the hard disk or data contained in an email messaging application. For the same reason, all email applications support password-protection and give you the opportunity to lock your email accounts containing a warehouse of confidential and business-critical information. For most of us, the task of remembering the password is quite horrifying and tormenting. Losing the password of your email account or some other application is a frequent problem faced by almost every user. This problem will indeed make all your work-related mails and other items inaccessible and pose a serious threat to your productivity. To avoid such circumstances, you should use competent Mail password recovery software.

I want to discuss a similar case of one of my close friends. He has a habit of setting strong passwords to his email accounts and follows a routinary practice of changing the password frequently. He has a multitude of accounts configured in various email clients. Well, for security reasons, changing the password in a week or two is often advised. However, this can also prove to be dangerous. You may easily lose these passwords and end up making all your email account data inaccessible.

Additionally, complex passwords are generally difficult to crack using the simple and conventional methods. But, at the same time, they are hard to remember. My friend had a similar problem. He lost the password set to his own mail account and made his account permanently inaccessible. His attempts to recall the password ended with no successful result.

In all such situations, it is wise to opt for a third party Mail Password recovery tool. Before going for a third party tool, do not forget to use all the inbuilt measures to recover your lost password.

There are a range of software in the market that can be used to recover password of all commonly-used email clients, such as Microsoft Outlook, Outlook Express, Windows Live, Incredimail, Mozilla Thunderbird, Netscape Communicator, etc. These software employ advanced brute-force attack to quickly get close to the exact password match.

Excel Password Remover to Reset Password of Protected Excel File

Dock icon for Excel 2011 for Mac (Photo credit: Wikipedia)

-->

Are you searching for an option to protect your Microsoft Excel sheet? Or you do not want any one to make any alteration in your MS-Workbook? Or you do not want anyone to even open your MS-Excel sheet until and unless you provide him/her a password? Then don't worry! This is possible with latest versions of Microsoft office. Confidentiality and privacy are the two words which developed the need of password protection in your Microsoft Office Suit applications. Therefore, you can save your important Microsoft Excel sheet in three different manners like:

• Password To Open: Applying this utility no one can even open your excel sheet until and unless he/she has the password. You can do this via Save As>>Tools>>Security Options and an existing one Main Menu>>Tools>>Options>>Security.
• Password To Modify: So, after applying this protection, you can protect your Excel sheet from unwanted changes. Thus, the people who only know the password can make alterations in your MS-Excel sheet. To do so go to Tools>>Protect Document or Unprotect Document

However, to remember a lot of password is out of the strength of humans and provide the same password to different files does also not make sense. Hence, various big organizations which use password to protect their Excel sheets also provide use MS Excel password recovery tool.

Let me tell you my example. I joined a new office last week, the person whose work I have to handle, had protected some of his Excel files and went without telling their password to anyone. However, to start the work I have to view few of them. The situation became worse when I found out that I can not even open some of the very important files. I immediately told the whole situation to my Team Lead and he recommended me to contact the system administration department. I contacted them and told them the case. Therefore, to recover Excel password, they installed a password recovery software in my computer and in just few clicks and short time I all of the passwords were saved in the text document format at the prescribed location in my computer.

An efficient Excel password remover software can recover both the passwords 'to open' and 'to modify'. These software use Brute-Force attack mechanism to give you 100% result. The software which I used provides various parameters that help to narrow down the search for Excel password. Hence, most of the software can recover the password from Excel sheets created in MS Excel 2007, 2003, 2002, and 2000.
