TLS / SSL - The complete sequence - Practical TLS

Understanding TLS/SSL involves understanding the interaction between the Client (web browsers, SSL VPN clients, etc...), the Server (websites, VPN endpoints, etc), and the Certificate Authority (the entity that issues Certificates). This video outlines the exact sequence of events that occur in the TLS ecosystem, and will explain the function of the Certificate, CSR, Public Key, and Private Key.
Seeing the whole process at 10,000 ft view will help you understand the smaller individual working parts as we continue to dive deeper and deeper into TLS and SSL.
This lesson is a free sample lesson from the the greatest TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals.

How do I translate it

[@Saiyan1987]

the best explanation I have come across by far - thank you!

[@scottspa74]

This really is a great overview that 'puts together' the full course. It's a great course, especially for those who appreciate visual aids for comprehension and 'putting the pieces together'.

[@PracticalNetworking]

Thank you, Scott =).

[@sayfakr8004]

Probably the best explanation of digital certificate mechanism. Thank you

[@rids22]

Wow.. what a series you have created.. End to end overview with simple explanation. Hats off to you Ed! Great work. Thanks for these videos.

[@PracticalNetworking]

If you enjoyed this, you'll enjoy the full Practical TLS course too! =)

[@joqiao400]

Best explanation ever! This is brief, clear, thorough and easy to follow and understand. Thanks for sharing!

[@PracticalNetworking]

You're very welcome =). Could you do me a favor? Do you mind sharing this video on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .

[@tom.bailey]

Best practical explantation I've seen and I viewed a lot of videos before this and had to exit them, thank you!

[@PracticalNetworking]

Glad you enjoyed this, Tom. I'd be willing to bet you'd enjoy the full course as well. =)

[@RayJay3000]

Watched all this playlist, incredibly useful lessons. Information is straightforward and very easy to understand even for those who haven't had any experience with encryption algos (like me). Highly recommended for any IT folks.

[@PracticalNetworking]

Glad you enjoyed this, Ray. =)

[@parthkulkarni3776]

A really great explanation of how all things work out in TLS. Thanks for making easily understandable diagrams, explanations. These concepts weren't clear well to me during engineering, and always used to scare the shit out of me. I believe these concepts will help me to atleast read few articles now independently to use these concepts in my work. Thanks again !

[@douglasfneves]

Amazing explanation, thank you so much!

Indeed! And even this was a simplification, so much more actually happens on the wire =).

[@ajayb9392]

This is the one which is connecting all the dots. Awesome. 1) In reality do we use 2 different symmetric keys? Just one symmetric key can do both encryption & hashing, right? 2) Do they negotiate which algorithms to use for encryption & hashing during SSL handshake?

[@PracticalNetworking]

A key is just a string of bits. Yes, you could absolutely use the same key (string of bits) to do both encryption & hashing. But it costs nearly nothing to generate more bits from a starting secret, and makes it twice as hard to brute force if you use two keys, so often the keys are used for only one purpose. In reality, 4 keys are generated, so you have different keys for encryption and hashing, *in each direction*. More details in the full TLS course =).

[@mirzadzafic8999]

Hello. Great video and great way of explaining this concept. I have question, am i right if i say that https request for web page is sent after client and server establish session keys?

[@PracticalNetworking]

Correct. The HTTP* request is sent *within* the SSL/TLS tunnel, and therefore after the session keys have been established by SSL/TLS.

[@matiashuartamendia7977]

are the keys generated via RSA? is signing via RSA?

[@PracticalNetworking]

The asymmetric keys can be generated with RSA, yes. Although, more recently that is beginning to fall out of favor .

[@matiashuartamendia7977]

@@PracticalNetworking so when we say signing we always refer to actual data encryption with symmetric keys?
