Awesome

[@hmzach9403]

My guy actually explained something in under 10 mins which my teacher couldnt explain in a whole year ong

[@pranay.bahuguna]

I was trying to get a clear picture of this whole CA certification auth process since hours and there came your video as a saviour 🤓

[@senju2024]

I bookmarked this. This is probably the hardest part for me to wrap my brain around on how digital certificates and public/private keys work. I think I gone through studying this part via books and other videos like 10 times and never truly get a clear understanding...until now. THANK YOU SOOOOOO MUCH. I think I finally get it!!!!!!!!!!!!!!!!!!!

[@samnnamani]

12 years in IT, having this muddled for so long, i just wanted a root understanding of cryptography and boom i found you, you made it so easy

[@praxisrebourne]

The amount of effort you've put into this is remarkable, probably the clearest presentation I have ever seen on this topic.

[@hassanasghar5568]

best video on Digital Certificates i watched till now

[@DanielSColao]

By far the best explanation of digital certificates. Thanks for sharing your knowledge.

[@ekambaramsainikhil9301]

I never comment on videos , but first time man I really love your explanation , I am exactly looking for this explanation , never stop making videos please 🥺🥺❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

[@salimbo4577]

best explanation of digital certificates i have even seen. You answered every question that was bugging me

[@darkpenink6730]

Dude, those who should have millions of subs are having so low subs.. Why God? I am in love with the creator and the content. Euphonic voice and lucid explanation. He looks cool with that grey shade of hair.

[@yusufraza92]

Thank you very much . Superb video my digital certificate concept got cleared now. Very well explained in detailed. Appreciate your efforts towards infosec community.

[@v1ctor0ng]

this is the most detail explained about SSL TLS handshake, and easy to understand too. thank you

[@sahaneakanayaka3394]

The best tutorial ever on Digital Certificates. What an explanation it was. Thanka bro ❤❤❤🙏

[@saranspan3536]

That was fantastic. Explained briefly and comprehensively. It helped me a lot. thanks a bunch

[@cpr3296]

I found very clear information after watching lot of videos and refering text books.. Really so informative..thank you

[@ttw06090]

By far the most detailed explanation on digital certificate I have seen

[@nareshgb1]

Excellent explanation - those diagrams are perfect. I have seen 3-4 other videos and THIS one cleared the confusion about how the certificate is built and what makes it "trusted".

[@destcert]

Glad it helped!

[@jamesdn12]

This was such a simple and elegant explanation of how and why this is done. Thanks so much.

[@destcert]

We're glad to know you find this helpful!

[@cybersniffer1]

Simplifying an explanation is a unique gift that can not be shared. Excellent!!

[@MatthewRawlings-l7q]

I have never understood this subject until this video. Thank you!

[@milesrennick1071]

I don't think I've ever read in the Security+ or CISSP "we don't actually send our public key". In the examples shown it's often the opposite! Very misleading of them. Thanks for the clear explanation.

[@ekambaramsainikhil9301]

yes that's true , I have the same exact doubt , but this video is the only video that explained very well about digital certificate , love this guy ❤️❤️

[@artyshan5944]

The most comprehensive explanation I have found so far, thank you!

[@destcert]

Glad it was helpful!

[@thejonnynation]

WOW!!! Thank you SO much! I have had trouble getting my head around certificates, and you've just explained in a way that I NOW GET IT!!! Thank you!

[@sarashan12]

Fantastic overview of Digital Certificates. I am bookmarking it.

[@geofftheriddler]

The clearest and most engaging explanation on this gnarly subject. Thx

[@androidery1999]

I've watch this video multiple times. Just perfectly presented. Thank You.

[@elankeeranraveendran1369]

[@Weerayuth5262]

I think this video is one of the best for understanding of Digital Certificate and PKI. I would like to thank "Destination Certification" and their team for such a good work. It's very helpful. Thank you.

[@PaulEllisBIGDATA]

Dude can't thank you enough. Video should have a over million views.

[@mikekorsak373]

Echoing what I have read and heard from SEVERAL to date - you are articulate, and simplify complex concepts, great job!

[@prawnydagrate]

Studying for an upcoming ICT exam, I was really confused because of how little information my textbook had about digital certificates as a way to protect data. This video cleared up all my confusion. Thank you!

[@destcert]

Glad to hear this video was helpful in your studies. All the best to your exam! We're rooting for you!

[@amyg6182]

Very simplified explanation. I'm understanding certification for the first time. Thank you. You just got a new subscriber

A great job done and explained easily right from beginning and how it works..... very clear and great explaination in a very simple way.. Thank you so much for the video

[@tech3425]

Absolutely loved everything about this video! From the animation, to the way you explained everything so calmly. Looking forward to seeing more useful vids from this channel

[@zakwillis]

Fantastic explanation!! Better than I’ve ever seen. Nicely done!

[@vineet0301]

Have never seen a video with such a clarity of concept and practical implementation, thanks for the video, great job. Just a suggestion , if you could include ocsp protocol in the entire process , it would be awesome

[@zyncer123]

Best explanation ever :) I tried googling about how does it work, a lot of them doesn't demonstrate on the point i was wondering.

[@datedatekyal3650]

Very clear explanation. I always find to know digital certificate, before watching your video I was confused with it. Now I know TLS and why use digital certificate from your video. Now I have clear understanding about digital certificate. Thanks you and cheers 🍻

[@RobFire3]

Awesome work Rob, thank you for your commitment!

[@destcert]

My pleasure!

[@AliShaikh_744]

Excellent video. Very easy to understand. I especially like the fact that you take care to sure exactly how the problems arise and how they can be solved. Thanks very much.

[@samratshinde3088]

This is one gem of a video, it helped clarify all the doubts with respect to certificates, always struggled with it. Haven't browsed your channel, but would like to know if you could show some technicalities like certificate generation etc etc. Thanks in advance.

[@destcert]

Glad you liked it! We'll check that topic for you

[@samirshaikh6494]

Best explanation ever. Thank you Rob

[@playstore-pz3po]

One Word.... EXCELLENTE!

[@techshan2185]

Thank you very much for explaining such a hard concept in a very easy way to understand

[@RajputSaab84]

Thanks for making these video, your videos makes learning simpler...!

[@dkupush]

Time - ~8:02 - 8:43 --> Alice won't be able to decrypt Baddie's digital certificate with CA's public key !! This is because Baddie's (forged) digital certificate was signed with a private key other than the CA's private key. Once Alice is not able to decrypt the received digital certificate she knows the server's digital certificate was forged.

[@oskarjankowski5709]

This is art. Beautiful.

[@calmeriver]

the best video I came across regarding this topic, thanks now I understand!

[@michaeleconomides4054]

You did a good job of explaining all this. The only minor flaw is that typically a normal everyday user like Alice wouldn't go to a CA to get a certificate, but a business entity (e.g. the bank) would.

[@vitusyu9583]

Good and clear illustration, digital signatures and certificates are always a difficult to grasp topic to me.

[@tarachslutions]

wowwwww .... never seen such a video. I'm amazed by the way you're explaining!!

[@destcert]

Your kind words mean a lot to us! Our entire team is cheering you on to succeed! 🙌

[@satish1012]

Great video! What does it mean every one in the world has copy of CA' public key. ? They come preinstalled means? Do we have all the possible certificates in the browser?

[@reveka-joytabalno5208]

thank you for your tutorials ❤❤❤❤ your videos are great! great visuals and great explanations 😊❤❤❤

[@billybuck2713]

insane vid. Thanks, extremely helpful, and answered most of my questions!

[@sirjohn6299]

You explained this so well. Thank you my friend!

[@noahderebe]

Beautifully Explained!!!!!!!!!!! I loved it.

[@renjumc]

wonderfully explained.. kudos to you!!

[@destcert]

Glad you liked it!

[@tarankaranth8782]

the best one in have seen !

[@Jupiterxice]

OMGGG thank you!!!! I am studying for my Security plus and you explain it perfectly

[@jakebrowning2373]

6:14 You say that the CA "encrypts" the information with the CA's private key. I don't think this is correct. I think the correct statement would be "the CA creates a digital signature for the information". In other words, the CA hashes the information, then encrypts that hash. So a certificate would consist of the information + digital signature. The client would then check encrypt the digital signature leading to a hash, they would also hash the information, and check that the two match. The "information" I am talking about is the these fields. en.wikipedia.org/wiki/Public_key_certificate#Common_fields At least the issuer must be unencrypted so that you computer can know which public key to use to decrypt the digital signature.

[@jded1346]

good explanation. Question : Why would a CA issue a cert to 'Baddie' and what makes Alice reject a certificate issued by a trusted CA?

[@alexanonymous5823]

many many thanks to you for such a detailed explanation it was very very useful!!!

[@destcert]

Glad it was helpful!

[@kgck15]

great video. one question. you mentioned the clieny uses ca public key to decrypt the baddies cerrticate ..since baddies cert is created and encrypted by himself how does cas public key able to decryt it?

[@PixeLabor]

best explanation so far

[@matthewtsang8268]

at 8:06, Alice is said to decrypt the certificate from the baddie using the CA's public key. but how is this possible? the Baddie doesn't have the CA's private key and could only encrypt the bogus certificate with its own private key. Then how could Alice decrypt the certificate with the CA's public key? im confused

[@arbnoramorina4036]

Very clear and very easy to understand. Thanks for your effort helping the others 👍

[@destcert]

You are most welcome!

[@joshuaeuceda4635]

Amazing job well done! Thank you for the epiphany!

[@Mature990]

Thank you so much for the security awareness among the community. There was a video on digital signature. It was extraordinary. However, it is not accessible/available anymore. Could you please let me know in order to access it?

[@YagoCarr]

Thanks for sharing such valuable information! I need some advice: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How can I transfer them to Binance?

[@PrasannaKumar-jl7qk]

Amazong video with crystal clear explanations. Thank you for this! I was looking into this to learn about Certificate pinning! So that the client always expects data from a single source. This introduces problems of not being able to rotate certificates regularly for clients like Mobile Apps where it would demand an update! Is public key pinning and certificate pinning the same? Can you do a video on pinning?

[@destcert]

Glad it was helpful! I have added certificate pinning to the list of videos I'll work on. Good idea! You're right, certificate pinning can introduce some challenges with certificate rotation. Public key pinning and certificate pinning are essentially the same thing. A certificate contains a public key - allowing use to verify the owner of a public key. We pin a certificate so that we are pinning the public key it contains. Fundamentally, it is the public key that we want to pin. Hope that helps! I'll create a video :)

[@ManinderSingh-hv1mq]

Very well explained 👍👍

[@VasanthSustiha1]

@Destination Certification Thank you so much Rob for this wonderful video and making it so simple and easy to understand! I have been going through a lots of article and videos to understand how TLS handshake works! nothing was really that helpful and it only ended up making me more confused with different opinions and information.. you can just lighted me the path to understand the TLS handshake and digital certificates (Two birds in one stone) in 10 minutes if wonderful explanation! thank you again :)

[@destcert]

Awesome! We're so glad you find this helpful! Watch out for more videos!

[@tarankaranth8782]

the best video on certificate. one question if baddie can somehow get hold of ca plublic ley then why can he get the owners identity and also recreate the certicate with his own public key inside. why is a private key required for all those things after all even the browser does not have private

[@eggdip]

Great video, thanks for creating. Looking forward to more topics.

[@destcert]

Thanks for watching! Lots more videos in the works!

[@Don-Carillo]

best explanation ever and i have seen a few

[@karrouchekarrouche1151]

Really Great video, thank you so much. Could you please make a video on how we can verify software using Digital signatures, software like Tor Browser, electrum....and explain please the digital signature

[@SJPYT]

8:00 Is that correct? I thought Alice wouldn't be able to decrypt the Baddie's certificate with a CA public key?

[@aaravdubey3734]

Great Video! Simple and Informative.

[@DemocracyManifest-vc5jn]

Please cover how this applies to enterprises intercepting and reading ssl over a proxy. all I know is they decrypt traffic for security reasons, to accomplish this they insert their own cert in the trust store.

[@johnjinesh]

Good explanation but one doubt (time 8:03 in this video), you tell that if badie sends his digital certificate, Alice decrypt using server's public key? how does that possible?

[@Victor-pq5kd]

This is a hidden gem, thanks for sharing!

[@christinalai3485]

Very good explanation. Many thanks !
