‫All right, how about we jump in here, guys?
‫So the first thing we're going to talk about is encryption or just for simplicity, symmetric encryption.
‫Right?
‫I have a text.
‫This is a beautiful text.
‫I have my data.
‫I have my image.
‫I have my block PDF file.
‫I have my HGP get requests and I want to encrypt it.
‫Right.
‫You have this input and using a key that is a specific called symmetric key.
‫You use it to encrypt basically everything on this text.
‫Right.
‫And then you'll end up with garbage data and to decrypt it, you use the same exact key and you get
‫back your text.
‫Very simple idea.
‫And that's called symmetric encryption because the same key encryption and the same key decrypts.
‫Yeah, we have another type of control, which is asymmetric encryption in order to communicate in a
‫in a in a networking architecture where I want to encrypt stuff between two parties, but we don't have
‫to discuss it in this video.
‫That's the idea of encryption.
‫And ever since we use encryption on pretty much every single place we can, we encrypt our passwords
‫in the database.
‫We encrypt the communication between a client and server.
‫She doubles everything.
‫And if you want to learn more, check out the playlist.
‫We talked about tearless transport, layer security.
‫Why it is important to encrypt, to encrypt everything where we can.
