Secure way of sharing a Secret-- One Time Secret!!


Technology has been evolved to the very best of its kind by now and mainly in the field of communication, the development is marvelous but sacrifice of privacy is the cost! Dig into the article to get the trick to send the encrypted message that can be handled only by the intended recipient




With the advent of the advanced technologies of communication starting from the Telegraph, Radio, Mobile Phones, Smart Phones (indeed Blackberry, iPhone, Android) ,Video calls(Skype,Facetime), Emails , Facebook, Twitter, WhatsApp etc., we are standing just an inch away from our dear ones and Business People though we are light years  (Just Kidding -- but indeed Hundreds and hundreds of miles) away.

But the notabene fact behind these communication made us lose our privacy a bit and we are the verge of the fact that we are being spied. Since  many of the servers and service providers (Not mentioning all though but some) are spying the database records of the customers to get the information they need to develop their business grow.

I am here to share a thought of a Service I recently got to know for sharing the very important messages so securely in an encrypted way and can be seen only by the recipient that will last for only a stipulated time, the ONE TIME SECRET. com website.

Lets take a deep dive to know how to send encrypted message using that.  (Seems I am sharing a secret with you!! :P )

Follow the Screenshots below or the Steps at your ease.

                                                                  Screenshot 1



Screenshot 2









Steps:

1. Login to the www.onetimesecret.com

2. Enter the Message (Secret) you wish to convey and type a Passphrase.

3. And after clicking the Create Secret Link will generate a link.

4. You will be directed to a new page where a link is generated for you.

5. Mail that to the intended recipient and you are done.

6. If the recipient is receiving the link and types the Pass Phrase you informed them, they can see your secret message.

Note: The Message will not be displayed if Pass Phrase is wrong and the link works only once.


Hurrah!  

Happy that I boosted a Sherlock in you! Try it.
