How does HTTPS work? What's a CA? What's a self-signed Certificate?

This 11 min video was more educating then an entire course of pluralsight on How HTTPS works. Thank you for this.

I would like to add, for clarity, that: 1. A message encrypted with a public key is used for secrecy - The message can only be decrypted with the corresponding private key, but you cannot verify who the owner is. 2. A message encrypted with a private key is used for authentication - The message owner can be verified if you know the corresponding public key, but is not secret. - This is why a web browsers have a record of public keys for CA Authorities - so they can verify that a "public key certificate" is signed by the a real CA Authority

I like it. This video, should be 1st video to view/watch, if anyone is starting with ssl, https, tls etc.

I was banging my head from 5 days to understand ssl setup to secure my kafka cluster.. And finally my woes are over. Thanks from the deepest bottom of my heart

I don’t know what it is but listening to videos that explain anything about technology in detail, I find calming. Loved the video.

Finally!!! I’ve been looking for so long to understand it. After this video, the whole process now makes all sense in my mind. Awesome channel by the way. Keep doing it!

Lot of videos talk what is SSL and how it works, but your video talks extensively about certificates explaining why one needs to have it !!! Your way of explanation is very simple, without graphics, jargon. Thanks a bunch!!!

Thank you very kindly. You explain better than most profs, teaching is an art and you’re a natural. Keep up the good work

Awesome. Came here for a refresher on HTTPS to prepare for interview and this video was way beyond what I expected to find in such a short video. You just got yourself a new subscriber. I admire people like you who can give so much information in a short time and in a way that is so easy to understand.

Dude! This is the most simple version of this complex topic I've come across. Hats off!

Thank you my dear man...I was looking for a technical-but-not-too-technical explanation. I am a developer who needs to know just enough and everything else I could find was too basic.

The diagram at 3:55 is very insightful. It manages to summarize what other videos fail to summarize in 20 minutes. Well done!

Simple and elegant explanation.. it works as apartment mail box. We provide Public address to all interested party, we buy mail box from apartment building management. USPS post mail in our mail box. Only we have private key to unlock mail box and read all mails. It similar concept applied using cryptography on digital platforms. Thank you very much for the video.

After watching a couple of videos on HTTPS, I came to this video, now I feel that I don't need to search for any other videos. Best explanation ever, thanks for this video.

Best explanation ever found on Youtube till now

Beautifully made complex concept so simple to understand. All these years read multiple articles but this 11 min video just made wonders and injecting the complete concept of CA and HTTPS into my head.... Keep doing more of such wonders...

Best, clearest and most concise explanation I've ever seen about this. Kudos!

Finally! Finally, someone explains where and how HTTPS uses symmetric keys for encrypted communication!

It´s delightful how you role the technical details out and still kept focused on the objective. Grats!

Wow a lot of concepts in a nutshell.... Very effective!! Just one suggestion to add - The CA certificate which is signed by the CA authority statically resides in the computer either through browser or - If we have our own CA certificate, then we implant it into the browser by copying into it. So practically we can also mention in the video where the CA certificate is stored in each case which is the only missing part according to me. Thanks a lot for the video again!
