HOW TO UNLOCK PASSWORD PROTECTED PPT FILE (READ ONLY)

In this blog, i want to share my some of tricks and experiences about  general hacking like unlocking password protected PDF, EXCEL, WORD, PPT etc.

Today i am going to teach you, how to editing and modify of any password protected PPT file.

First of all you have a password protected PPT file and after that apply the following step:

1) You have to change file extension. For example test.pptx to test.zip

     i) there are two way to change the extension as follow:
        a) directly double click on the particular file.
        b) through command prompt.


2) After changing the extension, open the .zip folder and find presentation.xml file.
   (i)    test.zip\ppt

   (ii)   copy that presentation.xml file.
   (iii)  open in notepad and search "crypt" and delete in between the quotes
  "</p:defaultTextStyle><p:modifyVerifier cryptProviderType="rsaFull" cryptAlgorithmClass="hash"cryptAlgorithmType="typeAny" cryptAlgorithmSid="4" spinCount="50000"saltData="IGD5MUl2SfTAX2r8Ma/sNw" hashData="Ve9wEKhZfdyqOTF2IlkrbekLv9Y"cryptProvider="" algIdExt="0"                           algIdExtSource=""cryptProviderTypeExt="0"cryptProviderTypeExtSource=""/>".
   (iv)  do not delete "</p:presentation>" in the end of the xml file.
   (v)   save the file and replace the original file into the zip folder.
   (vi)  rename .zip folder to .pptx

3) Here you go the file is editable and unprotected.

4) Try it and share it also.
