How to crack / open password protected pdf documents

Oftenly, either we forget our password or need to open any protected document for legal reasons. Mostly we end with guessing how to open password protected word document or excel or pdf documents. I came across such a situation to crack open a pdf document.

I did a google search and didn't find any suitable software that can crack the password. Anyway the technical expert Amit Agarwall says something to crack the password. Below is the extract from labnol blog where clear description is given……

There are basically two types of PDF protection - the original PDF creator can either restrict opening the PDF file itself or he can restrict others from modifying, printing or copying text and graphics from the PDF file. Here are a few possible workarounds:

When there are Copying or Printing Restrictions on PDF

Say you want to print a couple of pages from the PDF document but the document settings won't let you do that.

Open the document in Acrobat Reader or Foxit and capture the PDF page as an image using any free screen capture software. If there are multiple pages, you may try SnagIt since it can autoscroll and capture multiple pages of the document in one-go.

If you want to copy just a portion of text from some PDF page, use a screen capture tool with OCR features (like Kleptomania, Capture Text discussed here)

Alternatively, you can invest in commercial solutions like Advanced PDF Password Recovery from elcomsoft.com and PDF Password Remover from verypdf.com. These utilities may not recover the password for you - they'll just remove the restrictions from the password protected file. For more tips, check the Adobe PDF Guide.

When there are Document Opening Restrictions..

This is a very tricky case and there's no straight-forward solution to read PDF documents that are password-protected at the Open level.

The software will use methods like Brute Force, Key Search and Dictionary Attack to guess the password. They will try to use all possible character combinations as the password and so the process might take hours or even days and would really depend on your computer's processing power.

Advanced PDF Password Recovery Professional edition from ElcomSoft is a recommended option. When (if) the password is found, the program shows it, as well as the number of passwords which have been tested, and the program speed.

Legal Issues: - you maybe surprised to learn that these PDF password cracking software are absolutely legal and Microsoft even awarded ElcomSoft a Gold Certified Partner status.

Google providing search results before you complete search query

Long back Google proposed the idea of providing search results before any one completes their query and infact, the idea is now implemented what it is called 'contextual discovery'. The assumption revolves around the idea of being able to look at either a person's browsing profile or their location profile and serving up interesting data to them without them searching for anything.

Marissa Mayer, Vice President of Location Services at Google said "The idea is to push information to people", "its location in context. Inside the browser and a toolbar, we can look at where people have been going on the Web - then we deliver it. But it's a big UI challenge."

Google provides information based on a user's location on mobile phone while on PC, the search results would pop up in a panel on the browser complementing the user's own Web browsing. "We can figure out where the next most useful information is. In a restaurant, maybe it's a menu. Or maybe it's a social menu. It's about explicit and implicit location," she said.

The search is being done by taking users location as a piece of context for finding what they want without them actually searching for anything.

Mayer's explanations should be read alone with Google CEO Eric Schmidt's remarks at the TechCrunch Disrupt Conference in San Francisco in September where he said at some point in the future, Google's search technology will be autonomous. He had anticipated about the technology being able to offer users search results even before they've looked for them.

How to unlock / reset micro SD memory card password?

Some of the advice I got from my friends to unlock / reset micro SD memory card password:
1. The best way to unlock the micro SD memory card is to reach a mobile repair shop in your town. They will probably have a Memory card unlock. It’s a small device like card reader and unlocks the memory card. They will charge you up to 1$ here in India. But you can’t get all the data back. Try using Applications like recover my file after unlocking.
2. The other solution is to format the card you need a Memory Card Flasher. Buying it is not a wise decision, as you won't be getting into the same problem again and again. So carry it (the memory card) to a Cell phone repairing shop, who has a flasher, they'll do it for you. It’ll take 10 to 15 minutes to format a card (for 1GB). They may charge anything between 50(INR) to 150(INR), depending on how dumb he thinks you are! I got it done for 80 bucks (due to my impatience) @ National Market, Bangalore, India.
3. Put micro SD in mini SD adaptor and put in N73 nokia or try on others simbian nokia where you can put micro sd. with FE explorer go to C:,system>mmcstore and transfer that file to pc. Open with notepad and read pass... u can use other program for simbian who search for all password on phone, input micro SD and scan.
My other friend explained the same thing to unlock memory card in two methods……
Method 1: Recover memory card password, using Fexplorer. We need Fexplorer for this mobile hack. After installation, Browse to c:\system folder in your mobile phone. Here you would find a file mmcstore .This file is actually used to store memory card passwords in a mobile phone . Rename this file to mmcstore.txt and open with notepad. Now you will see the memory card password as it is, exactly.
Method 2: Unlock memory card passwords of Nokia Nseries and Eseries phones. The first hack to recover the password of memory cards will not work on Nokia Nseries and Nokia Eseries devices. Here we will use the remote lock feature for re-setting the password. For this, go to your pones settings >Security >Phone and SIM> and then allow Remote lock. The password of your remote lock will be the password of your memory card .So if you want to change the memory card password, just send an SMS containing your remote lock message.
