It's creepy how good you are at explaining things; i watched 3 of your videos and i always understand the key concept, thank you sunny

Your tutorial was very clear with just the right amount of verbal and visual info. Thank you !

Thank you for the tutorial. Everything is so well explained.

Awesome content.Finally this is the place where explanation was super simple

I have seen a lot of resources online about PKI. This is by far the best one in my opinion. The concepts are brilliantly explained in a simple and concise manner. Very easy to understand. Thank you!

Thank you Sunny! I just happened to find your video when I was looking for some information about PKI, and your video helped me a lot about understanding the concept. I watched some more videos that you created and I really liked them. You explained such complicated things rather simply and very clearly! I am taking Info. Systems Security online course at a university. I'm sure that I'll come back to watch other related videos as well!

Question about the example: What I saw on the PC only root CA public key was installed, but the certificate is issued by the intermediate CA, without installing the public key of of intermediate CA, how can the PC authenticate the received certificate?

Does the browser only check the validity of the self-signed certificate of the root CA? And if it's valid, it automatically trusts all intermediate CAs without verifying them?

How is the deletion of a certificate (revocation) carried out in a chain of trust if not all subscribers who use the certificate have access to a CRL or connection? Are there alternative ways or how is this solved?

how to become CA/intermediate-CA/Delegated signing authority? any CA will provide Signing certificate (certificate with signing right ?

much more in depth than Messer!

Is there a mistake in this video? At 3:56 you are saying that the hierarchical modell is limited because once the private key is compromised certifitcates will become worthless. But that's exactly the same issue with the distributed ones? I can't trust a single certificate if the root is compromised?

Thanks for your video, I was in mid of a confusion as my client sent a certificate which was not working in my modem. Suddenly I found in video that a ROOT CA's supplier and supplied to must be same. I checked and my certificate was wrong. Thanks again.

Sunny, question - you mentioned that purpose of PKI is to facilitate a safe transfer electronic transfer of data over the internet, is this definition same for SSL? Thanks.

To understand how SSL plays in this, you need to go a little deeper. This video will explain the role of SSL in the trust model: kzread.info/dash/bejne/mpmVxdqShdGseKQ.html

Thank you for your videos. These are great! Question: When gmail send his certificate, which is signed by the intermediate CA, does he send the CA also to me (client)? I might have the global CA to verify the intermediate CA later on, but I might miss the intermediate CA on my pc. So how does gmail make sure, I get access to the intermediate CA too?

@sunnyclassroom24

5 жыл бұрын

Good question. Public keys of most major intermediate CAs and root CAs have already been pre-installed in your browser (Chrome, firefox or Safari, even Edge :)) , Gmail server would not send CA to you. The certificate has the signature of CAs. Signature is verified by the public key in your browser. All big companies (such as Google) have even been the Intermediate CA themselves. If your browser has no public key of intermediate CAs for your service, will not be displayed. That is why we do not trust

What's the purpose of hierarchical trust model if for somehow the private key of the root CA's private key is compromised? Does it mean that all digital certs signed for intermediate CA are compromised and eventually digital certs signed for clients are also compromised?

@sunnyclassroom24

5 жыл бұрын

you are correct! if the top dog or intermediate CAs lost their private key, it would be definitely a bad thing for that company. However, it does not mean all clients are compromised. It only means that you cannot truly believe are truly encrypted. Anyway, as a user, we never trust a site we do not know. Simply we do not easily put credit card # or our confidential information to any site. We do not know if their private keys are already stolen. The original design is always "perfect", but we live in a "real" world. I don't disagree with you.

Do you think installing a third party certificate could have the possibility of breaking this trust chain? In some MITM attacks(used cain for arp poisoning to be specific, rather basic stuff, I was trying to learn how to use it) I'm used to install my own self signed certificate to the test machine so I don't have to deal with chrome alarming me at every page. Also, some school stuff requires you to install certificates onto your windows or android device, and even student tablets and smart board computers have meb's(milli eğitim bakanlığı - ministry of national education on Turkey) certificates pre-installed on them.

for a public website, you need a third party certificate. For a website for a small group of people, you can use the self-signed one. The function is the same. However, there might some other differences I don't know. I really appreciate your insights and knowledge.

@@sunnyclassroom24 Thanks. my English might be bad so I'm gonna ask it shortly will installing a third party root certificate to a system possibly break the security of all websites? maybe possibly through tools like cain&abel and stuff. since all other websites use different root certs it's not certain on my mind lol
