How to Send an Encrypted Email via Outlook

Encryption converts data from plain readable form to ciphered text and it requires deciphering the same in order to turn it to accessible mode. Sending and accessing encoded email messages require both sender and recipient to share their digital ID (also known as public key certificate). This post includes information on how to send an encrypted email via Outlook 2013 and lower versions.

Ciphering email messages prevents data from an unauthorized access. The technique turns data to inaccessible format and no alteration is thereby allowed through any invalid medium. Consequently, if in case it falls in the hands of unauthorized user; no modifications, additions, deletions or any other operation can be performed as the user will then require the decryption key to decode data.

Understanding Encryption Rules

For sending encrypted email messages, it is required that a digitally signed email message must be shared among sender and recipient that will allow each other to save their digital IDs to the Outlook Contacts folder. Without sharing digital IDs, it is not possible to share encrypted emails over MS Outlook.

Only recipient holding private key corresponding to the public key which is used to cipher the text can use it for deciphering the text for accessing it. Error message denying access to the encoded email message will appear if the recipient does not hold the private key.

Fundamentals of Signing Process

For assigning encryption, numeric value (also known as Checksum) corresponding to the set of bits in email message is calculated. Further, this numeric calculation needs to be enclosed by applying the same formula that is been used to cipher the message.
Checksum serves as the digital IDs or signatures, also known as digital certificate. Using digital key, these signatures are encrypted and then sends to the recipient address. The encrypted email message has three distinct components:
  1. Plain text
  2. Digital certificate; and
  3. Sender’s digital signature.
After receiving the email message, the recipient will check for the CRL i.e., Certificate Revocation List for analyzing if sender’s digital certificate has been withdrawn. If the signature exists on the CRL, the recipient will receive the warning message. If the digital signature does not exist on the CRL, the signature can then be decoded by using the sender’s public key which can be seen within digital certificate information.

Procedure to Encrypt Single\ Multiple Email Messages

When an encrypted email message is been sent via Outlook, the enclosed attachments will also get encrypted. Outlook provides a straight forward procedure to encrypt the email messages as and when required.

For MS Outlook 2013\ 2010

Encrypt Single Email Message

The necessity to encrypt single email message takes place when it requires sending or sharing some confidential message. Single email message can be encrypted using the following procedure:

1. In the email message window, click on 'Options'.

2. In ‘More Options’ group, click on 'Message Options' dialog box.

3. In the then appeared ‘Properties’ window, click on 'Security Settings'. 

4. Further select the checkbox that says ‘Encrypt message contents and attachments’ and then click ‘OK’.

5. Compose the message and click on ‘Send’.

For assigning default encryption on all email messages, the under mentioned procedure needs to be followed:
1. Click on the ‘File’ tab and click on ‘Options’.

2. In then appeared ‘Outlook Options’ window, click on ‘Trust Center’ and then click on the ‘Trust Center Settings’.

3. Under the ‘Encrypted email’ link available on the ‘Email Security’ tab; select the checkbox available with ‘Encrypt contents and attachments for outgoing messages’.

4. Further, click on ‘Settings’ if any of the assigned settings needs to be changed. 

Note: It is required that all the recipients should have the sender’s digital ID for decrypting and reading the messages.

For MS Outlook 2007:

Encrypt Single Email Message

1. In the email message window, go to the ‘Message’ tab and click on the sign available within ‘Options’ column.

2. ‘Message Options’ window will appear, click on the ‘Security Settings’.

4. ‘Security Properties’ window will appear, click on the checkbox available with ‘Encrypt message contents and attachments’ and then click on ‘OK’.

5. Compose the email message and click on the ‘Send’ button to send it.

Encrypt All Outgoing Message

1. Go to the ‘Tools’ menu and then click on ‘Trust Center’. 

2. ‘Trust Center’ window will appear; click on ‘E-mail Security’.

3. Under ‘Encrypted e-mail’ section, click on the checkbox associated with ‘Encrypt contents and attachments for outgoing messages’.

4. For changing additional settings, click on the ‘Settings’ button.

5. In the then appeared ‘Change Security Settings’ window, provide appropriate settings as required.

6. Click on ‘OK’ button twice.

As a whole, it can be concluded that encryption is a powerful mechanism to safeguard email messages and other data from unauthorized access. At the same time, proper understanding over how to send an encrypted email via Outlook application is also required. In addition, the basic knowledge over deciphering data is mandatory as without decoding the message, it cannot be possible to access the same.

How To Display View Count Below Your Embeded YouTube Video

YouTube video statistics such as view count & like count are very important factors depicting popularity of a video. YouTube displays these counts below the videos on its own site. But unfortunately when you embed a video in another site these counts never displayed directly below the video. Although you can view the count by clicking the info(i) button present at the top left, but anybody will barely click on that button to view the statistics. So here is a trick which can help you to directly display the count below the embeded video.

Lets have a LIVE DEMO before moving ahead

Following is an awesome video of Hanu Dixit with Michael Stevens (Vsauce). Have a look how the view counts work.

So how to display it below your own video

Displaying it below your own video is very easy. Simply copy and paste the following code in your site. You can also add it as a plugin in your side bar/header/footer section. It will automatically start displaying the view count wherever it will find an embeded video.

var myFrames=[];
var fetched = -1;
if (window.addEventListener){window.addEventListener('load', initProps, false);
window.addEventListener('load', loadViewCount, false);
else if (window.attachEvent){window.attachEvent('onload', initProps);
window.attachEvent('onload', loadViewCount);

function showViewCount(data){
 var div = document.createElement('div');
 div.innerHTML ="<b>"+data.entry["yt$statistics"].viewCount+"</b>"; = "5px"; = "table"; = "relative"; = "right"; = "Arial";
 div.innerHTML += "<div style='border-bottom: 2px solid #c0c0c0;width:100%;margin: 5px 0px 5px 0px'></div>"
 div.innerHTML += "<div><img style='margin: 0px 5px 0px 20px' src=''/>"+data.entry["yt$rating"].numLikes+"<img style='margin: 0px 5px 0px 20px' src=''/>"+data.entry["yt$rating"].numDislikes+"</div>";   
 myFrames[fetched].parentNode.insertBefore(div, myFrames[fetched].nextSibling); = (parseInt(myFrames[fetched].offsetLeft)+parseInt(myFrames[fetched].width)-parseInt(div.clientWidth))+"px";
 if(fetched < myFrames.length-1){

function loadViewCount(){
 var script = document.createElement('script');
 var videoId = myFrames[fetched].src.split("embed/")[1].split("?")[0];
 script.src = ""+videoId+"?v=2&alt=json&callback=showViewCount";
function initProps(){
 var allFrames = document.getElementsByTagName("iframe")
 for(var i=0;i<allFrames.length;i++){

Here are some of its benefit you will like
  • It works for multiple videos as well
  • You must not worry about the layout and alignment of already embeded video. Above code will automatically display their counts at corresponding places.
  • It uses YouTube API to fetch the count so it renders faster.
  • Like & dislike count also gets displayed below the view count

How does it work

Well, it works with YouTube API. The API returns the counts in JSON format which is later formatted to properly display in HTML. Following is the URL which fetches the count.

The script dynamically provides the video ID to above url and gets the response back.

Hope you all like it. Let me know your view via comments.

What You Need to Know Before Hiring a Computer Consultant

When was the last time you fixed a non-working gadget ? You have surely felt intense after successfully restoring it back to normal. The secret of being a computer consultant does not rely on technical knowledge or high IQ alone. Most of the time, you have to mix it with perseverance, passion and patience. There are times we think of directly consulting for computer repair service not thinking that we can do our share to fix the problem. There are also times that giving up and reaching help from others could be better option than personally addressing problems we can’t solve on our own. Without further adieu, here are some stuffs you need to know before deciding whether to personally fix computer devices or call a computer consulting company.
  1. Do not think immediately for the replacement of your defective device unless the hardware components are broken for good such that the internal setup is totally messed up. You can check your room for spare parts or ask your friends for parts so that you can save bucks. After having the parts, be sure to dedicate patience and perseverance in personally repairing the problem. In the middle of the operation, you might lose hope to continue so think of the possible outcomes first and whether to continue or not. 
  2. Review the device manual. You might feel ashamed of yourself when after a successful repair from a technician, you found out that your problem is enlisted somewhere in the troubleshooting section of your device’s manual. You could have solved it on your own and freed some money. Also when buying a new device, familiarize troubleshooting issues in the manual first so you can make a reference in future use. 
  3. You can seek help from your tech-savvy friends who might have knowledge on the problem of your device. Encourage him to help you out by treating him in movies or anything you can give as compensation for his service. It doesn’t have to be expensive in any way. Just satisfying his personal happiness and giving him his personal favorites are good to go. Take note that most people today are not really interested to help for free especially if learning the skill requires too much effort to acquire. 
  4. Browse online forums. There might be people around the world who experience similar issues with your device. You can tell if the forum is reliable by navigating to the views count on the page or simply peeking at the comment sections. For instance, you can see threads such as tablet repairing long island. The forum title might sound generic but going in-depth of the contents is worth a try. 
  5. Visit your manufacturer’s website. The most reliable online reference for the issues of your device is no other than the manufacturer’s site. If there is customer support available, ask a ticket or phone the staff to report your problem. Some manufacturer sites have also built-in forums so check it out. 
  6. Hire IT freelancers online. Today, there is now what you call "virtual workers" who can assist whatever your problems are. Good news is there are lots of computer technicians who go for freelancing jobs in the hope of serving more people while enjoying diversity. 
  7. Before hiring a freelancer, credit his previous works and client references so you won’t be fooled. 
  8. The bottom line is to call for repair centers in case you don’t find any alternatives for the fix. Calling a computer consulting company for instance won’t automatically make you spendthrift. You can work with your consultant so that next time, you can share your knowledge to your friends.
