Its time for our second Sunday School event, yaaayy! Based on the discussions from the previous session we have decided to conduct a Crypto-party. Sounds real fancy, doesn’t it? What could Crypto-party even mean? It is a workshop where you will be exposed to practical cryptography such as VPN( virtual private network), Tor anonimity network etc. These words sound too big and complicated? Let me break it down for you.

Imagine two people A and B share a secret. When they split up they need some way to communicate. So they use letters. A writes letters to B and these are written in some secret code. But there is another person C who wants to read these letters. So A puts these letters in a box using a lock that only she and B know the combination to. This is known as encryption. The box is then sent to B and he opens the box using the combination which was earlier given to him by A. This is decryption. Replace these physical locks with ciphers. Ciphers act like virtual locks. Now if person C tries to read the letters it would appear meaningless due to the use of ciphers. This is cryptography.

The Value of Encryption

“In today’s world of ubiquitous computers and networks, it’s hard to
overstate the value of encryption. Quite simply, encryption keeps you
safe. Encryption protects your financial details and passwords when you
bank online. It protects your cell phone conversations from
eavesdroppers. If you encrypt your laptop — and I hope you do — it
protects your data if your computer is stolen. It protects your money
and your privacy.
Encryption protects the identity of dissidents all over the world.
It’s a vital tool to allow journalists to communicate securely with
their sources, NGOs to protect their work in repressive countries, and
attorneys to communicate privately with their clients.
Encryption protects our government. It protects our government
systems, our lawmakers, and our law enforcement officers. Encryption
protects our officials working at home and abroad. During the whole
Apple vs. FBI debate, I wondered if Director James Comey realized how
many of his own agents used iPhones and relied on Apple’s security
features to protect them.
Encryption protects our critical infrastructure: our communications
network, the national power grid, our transportation infrastructure, and
everything else we rely on in our society. And as we move to the
Internet of Things with its interconnected cars and thermostats and
medical devices, all of which can destroy life and property if hacked
and misused, encryption will become even more critical to our personal
and national security.” more…
