All right, I'm super excited to start a brand new section.
It's my favorite section because I'm mostly walking into public key infrastructure, digital signatures,
cryptography and risk management.
That is why cryptography is my favorite topic.
I can talk all day long you want, but that won't be the situation because here we are to cover the
fundamentals of cryptography.
If you value cryptography and algorithms and encryption and encryption involves a lot of mathematical
concepts.
And since this course is not for the people who want to learn the detailed cryptography, we are not
going to learn about the probability.
The statistics, random numbers are pseudo random numbers or anything mathematical.
We are here to have an overview of cryptography because people what people do is they dive directly
into the mathematical cryptography before understanding cryptography.
So if you're looking for that cause, I suggest you to go to a website known as Coursera.
They have really good courses by famous professors from all the U.S. universities.
I'm not doing a paid promotion or any kind of thing.
It's my honest opinion because I've studied cryptography and mathematical cryptography from their website.
So it's better that you learn from the professors who have been teaching them for a long time.
So, all right.
So what are we going to learn in this wonderful section?
First of all, we are going to have overview of cryptography.
Then we'll see why we need cryptography.
Why where was the invention of cryptography and what actually cryptography does?
Then we'll dive into the types of ciphers will first understand us.
What is a cipher?
Then we'll talk about symmetric encryption or asymmetric encryption, which you have heard these terms
very commonly.
Then we will talk about RSA and we have an algorithm.
Then we'll talk about hashing what is a hash digital hash.
Then what is public key infrastructure, which has become very common and very useful because of this
pandemic period.
Public infrastructure.
What are digital signatures and what how do we exactly share documents over the Internet with full security?
Then we'll talk about the security alert and transport layer security.
SSL Lentulus.
It's actually B less.
It's not.
And then finally, we'll talk about cryptanalysis.
If you're expecting to listen to words such as Bitcoin terrorism or block chain, well, that is not
entirely cryptography.
That is cryptocurrency and it mainly lives into Blockin.
I will try to include a section on Block Jenah as well, but for the time being, we have presented
this section to you.
So without wasting any much time in the next lecture, we'll start right over with the overview of cryptography.
Stay tuned.
Keep moving forward.
