This post is a part of migration of my content from Quora. This answer quickly amassed 1k+ upvotes (not common for a no-name user like me) and a lot of interesting comments, in probably less than a week.

An email appeal to reinstate the answer was successful, but it was too late at that point.

It’s almost a mathematical field which has a profound practical impact on our lives. Generally, other guys must not be able to read your data, even if they get hold of it and know how it was encrypted.1 Some of the most noticeable everyday life examples: Most n00b example everyone comes across: Fb lbh svanyyl qrpelcgrq guvf! :-C If you didn’t know words are shifted by 13, this would be garbage for you.

Warning! Not your average bitching answer. Well, let’s do a quick recap of what Aadhaar, an authentication system, does.

The Aadhaar system compares this with its own record, and would like to verify with OTP and biometrics that the authentication request is indeed by the guy whose data is being processed.

Essentially, without any pseudo-childish-hacking fuss, it simply goes like this: DDoS attack is like a mob attack on a shop or a riot. When that happens, the shop is shut down and curfew maybe imposed on the area. DDoS is a coordinated attack on a web server, overflowing it with huge amounts of requests and traffic that the poor server’s resources are forced to become unavailable. Darknet is just like an area of abandoned houses.
