[@miratorimoonlightkim4413]

Sir, but why can't hacker intercept the message with digital certificate and create an entire new message and fake certificate and send it to alice?

[@sunnyclassroom24]

great question. our browser would check digital certificate if it is valid because our popular browser has pre-loaded with major CA's public keys and also our browsers would actively work behind scene with CA's servers to make sure digital certificates are real and valid.

[@praaksh]

Hi Miirar, Its a good ques! In a real world scenario, ideally an client(browser) interacts with the server and
when the server returns the digital certificate, the browser validates the CN(Common name) of the server to verify its identity, normally the domain name(say google.com) would the Common name(CN), when as mentioned by you, if the hacker intercepts the message and presents a fake digital certificate, the browser identifies that the Common Name
is different(say xyz.com) than that of the reqested one(which google.com), browser alerts us by throwing the error
message NET::ERR_CERT_COMMON_NAME_INVALID, Additionaly also the pad lock turns to red colour.

[@cyberlinksitcollege7traini557]

Good question .. actually the receiver will send the certificate of insurance to the CA and after CA confirm than it will start further communication

[@alphabetabs]

Great one !!! In the video when you have introduced a digital certificate you could have brought a hacker again and showed why it is not possible to pretend like Bob anymore. Please see if it can be possible to accommodate this.

[@RomanyKarius]

Very professional videos, keep on as you save hours for us

alert(1)

[@SahilRallySuperStar]

The query in Digital Certificate: Why would Alice pick Hackers public key and not bobs public key ?? In fact where from Alice gets to know that which public key I need to pick?

[@israilkarud9293]

i am confused with same question that why would alice pick hacker's public key

[@mangosdangoes6144]

@@israilkarud9293 She isn't aware that it has been swapped. Hackers intercept the message when it is being sent. Which means that the public key needed to decrypt the digital signature hasn't reached Alice yet.

[@SantoshSharma]

no need to choose key as he said. when server will send certificate, there will be key inside it and from there only it will perform further actions. whosoever will send certificate that key will be used. hacket cant send certificate as it would not be signed by trusted CA. if he sends its own then client will not trust it.

[@muruganandamm6685]

you're great sir. Thanks for your videos

[@mysocial]

The video don't tell if Alice can now forget about the public key from the public repository and use only the public key in the certificate. It doesn't explain neither how Alice get the certificate "along" with the message and its digital signature.

[@myhobbies1288]

Greatly simplified.. Even a layman can understand it very easily.. Sir as you explained PRIVATE KEY is used for DIGITAL SIGNATURE .
My question is what is the use of PUBLIC KEY?

[@kattopeter7280]

we use the Public Key to decrypt, that make authentication and non-repudiation

[@g3mint446]

Great explanation!

Sunny you are a champ..

[@kshitijkhanal8388]

Considering that i am requesting to google.com but on the way it is intercepted, destroyed and responsed by a man in the middle. Is it possible if a man in the middle intercepts and destroyes the senders request along with certificate and sends his message with his certificate issued by a trusted CA? How will the receiver know that he is talking to the person(google.com) he intends to, can it invalidate the certificate of the middle man?
