WHATSAPP END TO END ENCRYPTION INFO : HOW TO ENABLE & VERIFY

Recently Whatsapp released it’s update which provides it’s user a 100% security i.e Whatsapp End to End Encryption.

WHAT DOES THIS END TO END ENCRYPTION MEANS?

In simple and short words, no one other than you and the person you are chatting with can read or listen to your messages, your calls too are 100% private. Not even government can have access to them as all the messages will be locked and only you and your contact have the key (access) to those messages. This might create some problem in the countries where this encryption is not allowed according to IT laws.

Every message has a unique lock on it, for example, suppose you send a message “Hello” then in the Whatsapp database it won’t be stored as “Hello”, it won’t be plain text form rather it would be like “!@^%#” which is not readable, not even Whatsapp company would be able to decrypt these messages as they do not hold the key to it, which means your privacy is literally all yours now.

HOW TO ENABLE ENCRYPTION ON WHATSAPP?

Unlike other chatting apps like Hike or Telegram there is no need to enable the private mode manually for every single chat, if you and your contacts have the latest whatsapp version installed on their devices then this will get activated automatically.

As soon as you both update whatsapp, you will see a message “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.”

HOW TO VERIFY ENCRYPTION?

Now you need to verify if the encryption is enabled with a particular contact or not. First of all if you see the message “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.” then it means that encryption has been enabled but there are 3 ways you can perform the check:

1.) Open any contact in Whatsapp and tap on the name of that contact to check out their status/DP. There you might see a message with a green lock “Messages you send to this chat and calls are now secured with end-to-end encryption. Tap for more info.”, the green lock and this message tells that the encryption has been enabled.

2.) Tap on this message withing the chat and you’ll see a bar code with some digits below this, ask your contact to send you the screenshot of those digits which are displayed on their device and match all those digits with the digits which are being shown on your device, if they match then the encryption is enabled.

These digits are different for all of your contacts.

3.) Scanning the code: Just below those digits you will see a button “Scan”, tap on this button if the other phone (your contact’s phone) is with you, scan the code and if it shows the green signal then you’e good to go.

Although some users have reported seeing the red alert even they had everything correct, this might be bug which may see a fix in upcoming updates.

How To Remove Virus From Computer Without Antivirus

Can you remove a virus without anti-virus software? The short answer is yes, but it's not easy. Sometimes, depending on how nasty the virus is, you'd need to be a computer genius to successfully remove a virus manually. However, if you are somewhat technically savvy, you can try few things before opting for anti-virus software protection.

Why is it so Hard to Remove a Virus Without Software?

A hacker, or sometimes a team of hackers, who create computer malware all have at least one goal in common. That is to make it as difficult as possible to remove a virus they create from your computer. Some hackers are very intelligent and spend countless hours brainstorming ways to hide corrupt files all throughout your computer, making removal extremely difficult. In general, you cannot simply use Windows Add/Remove software tool to get rid of most viruses today. The display icons for the virus may disappear, but the virus will still be running, hidden in the background on your computer, and continuing to wreak havoc on your system.

In order to remove a virus without software, you will most likely need to search online and download a long list of instructions. You will need to know your computer inside and out and have a good chunk of time to dedicate to the manual removal of a virus. However, if the virus that ails your computer is not all that malicious by relative comparison, a few generalized quick steps, listed below, may or may not do the trick.

Some Quick Steps to Try to Remove a Virus

1. Hold down the CTRL, ALT and DEL buttons simultaneously – this will launch the Windows Task Manager. Once the Task Manager launched, click on the Processes tab. Look through every single process, which is a program that is currently processing information on your computer. If you see anything that looks unfamiliar, search the file name on the web and see if it's connected with any viruses. If you're confident that a particular file is corrupt, click the End Process button for this file.
2. Launch your System Configuration utility and click the Startup tab. This lists all the programs that automatically run once your computer is booted. Most viruses launch themselves whenever you load up your OS, so again, look for any odd or unknown programs on this list. If you see a program with a surefire red flag, delete it from this list.
3. Click the Start>Computer menu and go to your hard drive utility. Delete the viral files directly from your hard drive. This may or may not delete the virus in its entirety.

Remove a Virus Easily With Software

If you have a very nasty virus, removing it manually is going to consume a lot of your time. If you are not particularly tech savvy, trying to remove a virus manually could be a waste of time if you're not successful, and it will give you a headache in the process.

The top-rated anti-virus software suites have a high rate of success when it comes to removing many types of pre-existing infections on your computer. The best anti-virus software can also protect you from nearly 100 percent of future threats. Since this software ranges in price from as little as $30 to $60, many users find that using anti-virus software to remove a virus is by far the best solution.

Adobe PDF Guide

Adobe PDF is probably the best format for sharing documents as the layout and formatting is preserved across all platforms, the documents are read-only and also because most computers and mobile devices can easily open PDF files.
 This guide shares a host of useful things you can do with the PDF file format with the help of software tools and web apps that don’t cost a penny. You can edit PDF files (no Adobe Acrobat required), combine multiple PDFs as one, extract pages from PDFs and so much more. Let’s get started.

The Best PDF Tools & Apps

1. How do I create PDF documents without Adobe Acrobat?

You can use Google Chrome to print web pages as PDFs  without any extensions. Mac OS has PDF printing capabilities built-in while Windows users can install a virtual PDF printer like Nitro Reader to create PDF files from any Windows application using the regular Print command – just choose Nitro from the list of available printers.

SaveAsWWF from WWF is another PDF printer that creates printless PDFs. The other popular alternative is BullZip for Windows.

2. I don’t want to install any software. Are there any web apps for converting a bunch of documents to PDFs?

Sure. You can upload your documents to Google Drive and then export them as PDF files using these special links. Alternatively, you can email the documents toattachconvert@pdfconvert.me and perform the conversion by email. The latter options comes handy when you need to convert documents to PDFs on a mobile phone without any apps.

3. How do I convert a PDF file to another format like Word or HTML?

Upload the PDF document to zamzar.com and you’ll be able to the convert the file to other formats like doc, html, text, and more. Or you can use your Gmail account to convert PDF to HTML.

4. Someone sent me a PDF document in Chinese. How do I translate the PDF into English?

You can easily translate PDF files from one language to another using Google Translate. Go to translate.google.com, upload the PDF file, choose the destination language and hit the Translate button. The document text is translated though the formatting won’t be preserved.

5. How do I edit a PDF document?

PDF files are essentially read-only documents but there are workarounds to help you edit PDF files.

6. What is the easiest way to extract text from a scanned PDF document and use it in a Word document?

You can easily extract text from regular PDFs using the text selection tool in Adobe Reader but for scanned PDFs, Google Docs OCR is a good choice. Upload the scanned PDF document to Google Docs, select the option that says “Convert text from PDF and image files to Google documents” and then choose File – Download as Word to save the extracted text.

Alternatively, you can download FreeOCR, a Windows-only app for extracting text from PDFs.

7. How do I merge two or more PDF files into one? Can I also change the page order in the PDF?

You should use PDF Fill, a versatile PDF editing tool that lets you combine multiple PDF files into one. PDF Fill can also be used for rearranging pages of a PDF file or for rotating pages – a handy option for fixing the orientation of scanned PDFs. And if you prefer online apps, a good option is PDF Mergy.

8. I have a restricted PDF document that neither allows printing nor can I select text from the PDF. Can these restrictions be removed?

You can use online services like PDFUnlock.com or freemyPDF.com to remove all common restrictions around a PDF file – such as print, copying, etc. – without requiring any passwords.

9. Some PDF files on our intranet are password-protected and the employee who created those PDFs is no longer with the company. How can we open these PDFs?

There are several workarounds to help you open password protected PDFs. The PDF Unlocker app from AppNimi.com tries to guess passwords for your PDF using the Brute Force algorithm.

Alternatively, you can completely remove passwords from PDF files that are frequently viewed and instead place these files inside a password-protected folder of your computer.

10. How can I apply annotations or add text notes to my PDF documents?

You can use the free Adobe Reader app, available for both Mac and Windows, to annotate and comment inside PDF files. Go to the View menu and choose Annotations under the Comments menu. The toolbox has tools for highlighting text, you can add text blocks, create freehand drawings or even add sticky notes to the document.

Alternatively, use PDF Escape to add annotations, call-outs and text to your PDFs online in the browser without requiring any software.

11. How can I fill PDF forms online without Adobe Reader?

Go to PDF Filler, upload the PDF form and start typing. You can even pull PDF forms from your Dropbox or Google Drive.

PDF Filler will convert your PDF form into images and the user can type right on top of these images. When you have filled the form and are ready to print, the images and user text are combined into a single image. The other good option isFillanyPDF.com that is free as well.

12. How can I add watermarks or even my signature to a PDF document?

First draw your signature in Paint (or other photo editing tool) and save it as an image. Now open Adobe Reader and choose Tools – > Place Signature. Copy-paste that signature image anywhere on the PDF page. You can use the same technique to insert watermarks inside the PDF.

If you are on a Mac, open the PDF file inside the Preview app and choose Tools – Annotate – Signature – Create Signature from Facetime Camera. Sign your name in blank ink on a piece of white paper, hold the paper up to your webcam to scan the signature and you can then place it anywhere in the PDF.

13. I have a PDF ebook that contains 200+ pages. Is there a way to extract selected pages from the PDF and save it as another smaller PDF?

You can use the free PDF SAM (split and merge) utility to extract one or more pages from a PDF document and save them as separate PDFs. The tool, available for both Mac and Windows, can also be used to merge multiple PDFs into one file.

14. How can I protect my PDF documents with a password?

Upload the PDF file to pdfprotect.net, set a security password and export it as PDF again. The service can be used to password-protect files up to 10 MB in size.

15. How do I embed PDF files on my blog?

You have several options. Upload the PDF file to Google Docs and then embed it in your web pages using the Google Docs Viewer. Alternatively, upload the PDF to document hosting sites like Issuu, Scribd or SlideShare and use their Flash based viewer for embedding PDF into your web pages.

Bonus Tip – Manage your PDF collection

Did you know that you can upload all your PDF files to Google Play and read your PDFs in the web browser or any of your mobile devices. The Google Play Books app is available for both Android and iOS platforms and thus your collection always stays with you wherever you go!

How To Setup Wireless Network without a Wireless Router

Let’s say you have one internet connection at home that you want to share across all your desktop and laptop computers, your Wi-Fi enabled mobile phones, tablets, video game consoles (like the Xbox), digital photo frames and any other wireless devices that you may have at home.

How do you do this?

The easiest way to setup a wireless network, as we all know, is with the help of a router – just attach a wireless router to your modem and any Wi-Fi enabled gear, that’s located inside the signal range of your router, will be able to connect to the web using that lone Internet connection.

Setup Wireless Network without a Wireless Router

Now consider a slightly different scenario – you have all these Wi-Fi enabled devices at home but there’s no router. Well, there’s no reason to buy one because you can still easily setup a wireless network as long as your computers have a wireless network adapter*.

Most new desktops and laptop computers are already equipped with internal network adapters so you are ready to go without a router.

If your computer doesn’t have built-in wireless capabilities, you can either buy aUSB network adapter that plugs into the USB port of your desktop or go for awireless adapter that directly plugs into your notebook’s PC Card slot. Desktop users can also opt for an internal wireless PCI card but you’ll have to open the computer case in order to install this network adapter.

Create a Wi-Fi Network without a Router

Now that you have everything in place to create a Wi-Fi network, let’s actually build one.

For Windows XP and Vista users

If your main computer, that is already connected to the internet, is running Windows XP, Vista or even Mac OS X, you can set up an ad-hoc Wi-Fi network and the other wireless devices can then connect to the web via this ad-hoc network (also called a computer-to-computer network).

Wired Connection In, Wireless Connection Out

It’s an easy process. To set up an ad-hoc network in Windows Vista, go to Network and Sharing Center from the control panel, select “Set up a connection or network” and choose “Set up a wireless ad hoc (computer-to-computer) network”.

Make sure you select “Save this network” option else the ad hoc network will be removed if no other computers / devices are connecting to the network.

Turn on Internet Sharing in the next screen and now your other home computers can connect to the ad hoc network just like they would connect to any regular wireless network. Setting up an ad hoc network in XP takes a couple of extra steps but also make sure the host computer is running at least XP SP2 or SP3.

For Windows 7 users

If you are on Windows 7, you can instantly turn your  computer into a personal Wi-Fi hotspot without having to configure anything. All you need is a free software called Virtual Router and the computer connected to the internet must be running Windows 7.

[*] Virtual Router works will all editions of Windows 7 except the Starter edition because Microsoft has disabled the Virtual Wifi feature in that particular edition.

Using the virtual router is simple – just run the program on any Windows 7 computer, assign a password and that’s it. In the above example, I used the Virtual Router to connect an iPod, an Ubuntu Linux laptop and a Windows desktop to the Internet via a Windows 7 notebook where that virtual router software was running.

As new devices join the Wireless network, their assigned IP and MAC addresses instantly appear in the Virtual Router window. And you can click the “Stop Router” button anytime to deactivate the hotspot and disable Internet sharing.

Virtual Wi-Fi vs Ad Hoc Wireless Networking

To set up Ad Hoc networking, your main computer needs to have an Ethernet based Internet connection as well as a Wireless (WLAN) network adapter. In the case of Virtual Wi-Fi, the Ethernet card is optional so you can turn a laptop into a hotspot even if your laptop itself is connected to a Wireless network and not to an Ethernet cable.

Computers and other wireless devices in ad hoc networks must be within 30 feet of each other but there’s no such restriction in the case of Virtual Wireless networks.

Ad-Hoc wireless networking is available on Windows XP, Vista and Windows 7 while Virtual WiFi, which is much easier to setup, is available on Windows 7 or Windows Server 2008.
