Sir yr teaching style is amazing 😌...

[@user-tk9zc8fc7e]

Jay will encrypt the message using Veeru's public key and veer will decrypt the message using Veeru's own private key, other wise if Jay encrypt the message using Jay's own private key than, than that message can also be read by Gabbar(where Gabber is not intended receiver) as there is a chance of Gabber having the Jay's public key

[@DK-hn9or]

No sir is right, because the purpose of digital signature is that the receiver should know from where the message is coming.
for encryption, we will encrypt msg using receiver public key.
In short,
step 1 : first encrypt msg using receiver public key - confidentiality
step 2 : encrypt again using sender private key - digital signature which gives authenticity

[@user-ic5xz9iq2h]

Bas kal hai exam aaj padh lu thodha se 😂😂😂

[@itmanpaki2979]

Very nice explanation. Let me correct if I am wrong - If the objective is ' high confidentiality' means Jay's message can only be decrypted by veeru then Jay encrypt the message using veeru's public key and only veeru can decrypt the message by his private key.

[@anuragkumarsingh1272]

In this case veeru will not come to know from where the messages is actually is coming from means from any valid source or from attacker because here the verru will always be able to decrypt the message with own private key if the message is encrypted by his public key

[@gaganvishwakarma6494]

But , if the message can be decrypt by jay's public key then anyone can decrypt it as Jay's public key is globally available , isn't ?

[@ilmabinte_inayat7110]

Kl. Paper hai or phele baar dekha topic thanx God ap ki vdo dekh li

[@sanjayphanshikar698]

The hashing part is missing from the contents.. the obvious question is what will receiver do by decrypting the signature using public key and how will the receiver understand if the contents are meaningful. It contains the hashing on the plain text i.e. message to be send to receiver which the receiver can verify by matching the hash at its end. Thanks

[@ramanmahapatra1514]

@5minutesEngineering Sender's public key is available with all the members who are connected to the network. In this case, Jay's public key is known to Veeru and Gabbar. If Jay encrypts the message with his privet key, then even Gabbar can intercept the message and decrypt it with Jay's Public key. Hence, this method isn't secured.
In my opinion, the sender must encrypt the message with the public key of the receiver. As the privet key of the message is only available with the receiver, noone else can decrypt the message. Please confirm this suggestion.

[@shubhampandey2597]

It's only authentication not security

Good explanation sir, but I have doubt the public key of jay is also know to other people in the network so it might be possible using the of jay anyone can access this message in between the communication... So its break the confidentiality rule....it is not secure then

sir there is an issue as jay's public key is available to everyone so if jay send his msg in private key then there 3rd party could also be able to decrypt it using jay's public key. so i think it must be . jay will send his msg using viru's public key so when it reach to viru then viru will be able to decrypt it using viru's private key which is restricted to viru only

[@sarweshgiri6768]

Sir in this case the private key of jay is used while sending the message so on the other hand anyone can access the message sent by jay using his public key this can lead to confidentiality breach. Can we use th public key of veeru on jay side to encrypt the message and sent it to veeru only so that he can decrypt the message by using his private key ?

[@mncsrecruitment]

Sir if jay send msg by its private key then ...his msg anybody can open using thier public key ,so encryption is not follow, if encryption is done only when jay send msg using by veeru public key nd Veeru received msg by its own private key .

[@FaisalMalik-mw7kd]

Yes you are right...

[@shoaibhassan329]

Yes topic clear nh h yahan per bcz reciever ko pata nh lagega k msg such m jay ka h k nh... Ager hash function lagen tab pata lagega... And ager Asymmetric kry cryptography use kren tu its Become Confedential then koi b hack nh kr paega. Kr b liya tu change nh kr paega na hi decrypt.

[@harshitpal5558]

If Jay sends msg using veeru public key then in that case confidentiality is break cuz anyone else like basanti can also send msg to veeru using his public key that's why we use the combination of both public and private key
Step1 Jay encrypt the message using his private key so that recever gets confirmation about authentic sender
Step2 now Jay will encrypt the msg with veeru public key so that no one else may able to open that msg
..
..
And then he send now we achieved both integrity and confidentiality of aur data which we send
