SSL/ TLS HTTPS process explained in 6 minutes

welcome to this presentation about SSL/TLC  HTTPS process encryption authentication process we encounter SL / TLS every day only for example to our online banking we see in the address bar of our browser the log I can and also of the HTTPS which is indicating that this connection is secure.We just see that this side is using encryption, the communication is encrypted,

how to get a security certificate

Difference between ssl and tls

but the identity is not verified, or in this case no encryption at all is happening the whole communication is sending in text what are; the benefits of this process for one hand the encryption for sure and the other important things of Education how to trust go daddy secure certificate which basically just means ;

that I’m sure that the person who isn’t talking to is the one that I he claims to be to understand the TLS encryption process we need to take an encryption.

How to enable tls and ssl protocols

Let’s say L is here wants to send a message to Bach Bob over an unsecured -buyer or vice versa in that case Elias who has hear the message in our case just- high ciphers and groups the text with the first upon agreed symmetric key outcomes cipher text that can be transmitted over and secure wire so a third person like if here can listen in on the transmitted –

messages but they can make themselves because it’s ciphered and only Bob who receives it who has the same key ;

that’s the same no other way around so first he deciphers described message with the help of the key and out comes the unencrypted message hi so far.

The only problem they cannot transmit this key over an unsecured wire in the first place cause if here could listen in on that too and also decide for the whole communication that follows up ;

Along Came here’s a and the public and What is a certificate?private key method in o-ur case again here first Bob generates a set of keys who fit together called.

How does ssl encryption work
The key pair he decides one of those he -will never release and keep for himself which will be the private key and the other one is called the public;

key which he releases to whoever he wants standard ssl certificate wikipedia  even if here could get hold of the public key and Ellis in our example who wants to transmit the secure communication overhead wire takes again the message high and Crips it with the help that time of the public heat the ciphertext is here trust me –

get over the unsecured buyer and only Bob who again now that we do know; about symmetric and asymmetric encryption we do have; the tools to better understand TLS encryption process here it is let’s say I’m here and my browser, in fact, was to establish SL session with this secure website . Com each my browser sends first is.

Hello message over this unsecured buyer then in the second step server would respond business certificate which includes his public key and science from that point on forward.I have here his public key i will authenticate and verify ;

Tls vs ssl encryption

in the surface that the signature of this certificate we will come to that in the next slide and then I would make up I a unique symmetric key and crypt that unique symmetric key with his public key would send it back to the server;

and secure wire and with the help of both; met mechanisms at the end only me and the server know this symmetric session key we will use from that point on forward is Ethel session” is established now that we know that our line is secure the only thing left is verified the identity how to get secure connection of the other party .Just to be clear SL also works without it you just see like this symbol in the browser which indicates that the SL session is established but like.

I said without verifying the identity know how do Certification authority advanced  we do verify the identity so we don’t get any error in the SSL certificate that was sent to us by the server before which includes his public key and also the signature of the so-

called Certification ;Authority or short CA so this certification authorities and their certificates are already shipped within every browser let’s take a look at Firefox for example when I go to options options.

Insecure transport weak ssl protocol

I go to advanced certificates you certificates I see all those are the authorities there are over 600 private company government and in fact.We rely on them that they verify other parties towards us as for the conclusion SL meaning TLS is a great thing, but the ca system is its; which point i thank you for watching and wish you a safe Internet experience
