Explanation of Asymmetric key Cryptography with example is given in this video.
Asymmetric cryptography, is a cryptographic system that uses pairs of keys. Each pair consists of a public key (which may be known to others) and a private key (which may not be known by anyone except the owner). It is Important for UGC NET and GATE.

My college teacher was teaching us this for 2-3 days and I couldn't understand it but after watching your 8 min video I actually understood it. So thank u so much!
The same thing happened with me Thanks to this channel I understood it.
@@khushipitroda385 yesssss he is da best🤩
@@khushipitroda385 👍
itni si concept bhi nai samajh paye? laanat hai
@@parthsarthisingh4549 😅
I learned this in my engineering in 2010. I understood this today on 2022. Thanks 👍🏻
I have to say. Simple yet excellent explanation of a complex topic.
I have been trying to understand this since months but u nailed it. Try giving example how private and public keys encrypt and decrypt the data. Like 6 is data encrypted with private key 2 so 8 and encrypted with public key 5 so data is 13 and now decrpt process
wow
Sir, please make a video for digital signature.
you are a born teacher....Perfect explanation....heart to heart :)
Sir but attackers can also attack on B's public key na?
🙂↔️🙂↔️🙂↔️🙂↔️🙂↔️.. classic.. this guy needs award
This is awesome. I've been confused about this concept for years and you made it crystal clear in minutes. Thank you so much. More power to Gate Smashers
mee tooo
Mee to
Allah apko khush rkhy ❤
Extraordinary teaching skills teacher. Thank you
Best...... Explanation of cryptography, encryption........ 👍
Sir you are great ❤️aap jaise teacher college me kyu nahi milte👍🏻
For the first time i got this topic clearly, waiting for more stunning videos
Meto bro
Great job sir... I understand very clearly..best teaching for everyone.. Sir ur voice is awesome 😁
Line mar rahi h🤣🤣
Sir aise to B ki public key bhi sbke pass hogi... How does it authenticates the identity of sender?
And how this can be used in filing of returns using digital signature?
Good evening Sir
I am watching from Denmark and want to thank you a lot!
I just have one question. Under the figure B, where there is written public key B and private key A... should that have been a B instead? So it was public key B and private key B? :D
Yeah, you figured it well.
That is indeed the private key _B_ .
@@ajaykumarprasad8849 Thank you for the clarification :) Have pleasant day
Love you man... Diploma ho ya Degree, ap jarur yad mein ate ho aur ate rahoge sir....
Sir agar A ne B ki public key used karke B ko massage send kiya to another public B key used kr ke dekh sakhte hai na?
Awesome sir
Nice explanation, great teaching I can understand very well,thank you so much 🙏
One man army to teach all the subject of CSE on TH-cam
in what form do these keys come? password?
A very fine approach to make us understand the concept ...Great work done . Thanks !!!....keep it up.
very well presented !!please upload some videos on big data and cloud and iot and linux for nta net
Best teacher award goes to u sir ....thanks
Thanku sir
Absolutely best explanation! I wish more videos were uploaded for cryptography. I'm having end sem examination starting next week
Beautiful demonstration. Thank you for your effort
I have watched n number of videos to understand this concept , but failed to do so . He made it very simple to understand it . Remember one thing brother the money you are earning from this platform doesn't matter but the blessings you are getting truly matters. Thank you
I am a working professional in IT company and watching this video to explain my manager about the cryptography concept in technical term. Perfect explanation 👍
Yes you are born to teach us. If You teach any topic in this world we get it. God Bless u alot. No one is even close to u.
Superb explanation... 👌
i'm a student from sri lanka... i got this point clearly only from you. even it in hindi. thanks a lot. if u can please activate English subtitles...
Sir is all your networking tutorial enough for UGC net or I have to refer other lectures also????
sir your voice is very similar to raftaar's voice...anyone agree???
Face bhi😅😅
Play it in 1.5x
Superbb . Sir plz mcqs b krwa do es topic per
why you put the 300K in the thumb? who cares. I just rejected watching, paused your video and typed this message. if it was 500M or 1B (billion) then it would matter. ukh
sir your teaching is excellent. please make videos on data structure and toc. before this ugc net exam.
Thank you so much sir....
Nice video👍👍👍
Its really nice👌
Hello sir ,
In this case ,
A can also share his public key with B
Then encrpt the msg with his private key
B will decrpt it through A's public key
Is it possible ?????
Sir, I have a doubt.
According to you, if a message can be encrypted or decrypted using a nodes public key or private key. And the nodes can broadcast their public key to other nodes.
Then any intermediate node that has the public key can decrypt the message making the communication non-confident again.
Can you please explain?
As shown on your white board; Receiver B has Pub B key and Priv A key(instead of Priv B key);
Is it mistake on board or i am mistaken pls clarify.
Thanku sir 🥺😊
Bro where is full playlist of this course plz tell....
I m seeing that lec80, 81 , that's why

Thank you for video Sir Ji, please next time step a little bit away from board so we can take screenshot !! Thanks😊🙏🏽
Perfection at its best 💖
@gate smashers sir whats is best option in research cryptography or network secuirity...???
Superb👌👌
Bilkul clear hogaya
dude public key is only for locking and private only for unlock
you are teaching wrong
i don't understand one thing
agar sender message B ki key se encrypt krega then it means ki beech mai koi bhi B ki public key le skta toh fir why can't intruder decrypt the code back into simple by using B ki public key jab incryption public key se kiya toh decrypt bhi toh kr skte
?
As you said encrypted by public key can also be decrypted by public key.... Then if we send public key encrypted message it can be decrypted by anyone... Because multiple people can have the receiver's public key.....
no i said a message encrypted by public key can be encrypted by private key not public.
@@GateSmashers you mean* decrypted
Thanks sir ji,simple and plain explanation helps me a lot.i think you need to update your channel name it is not gate smashers but put only the Only Smasher because it is not only of gate Aspirants
Can we Decrypt from Public key of reciever if we encrypt from public key of reciever ?
Thanks a lot ....you really made me clear about the topic
3rd case non repudiation ke liye use hta h not invalid because the sender can't deny sending the message because it is being decrypted by senders public key
Sir please make video on twofish key cryptography.
thank you !
Love you sir
Superb sir 👏👏👏 kal papr hai or aaj hi ye concept clear howa hai thankyou so much
Sir ye koi batata hi nhi h
Aaj tak mai isi me confuse tha ki encrypt ho kaise rha h massage🙏🙏🙏🙏🙏🙏🙏🙏
May Allah bless you sirrr👍ek dam clear explanation, sir Mera ek doubt he ke jab a ka private key b ku Pata he Matlab vo private nahi hoga na, Matlab a jab public key of b use karke encryption kare aur b aake b ka private key use kare aur decrypt Hota he na, pls bole
Bhai tum na hote to Eng. ho hi na pati kisi ki ................ 😂😂😂😂😂😂
for sending messages either B "will know the receiver public key are not?
Everyone knows the public key of others
0:51 caption will make two kisses one public and one private🤣🤣
Watch full add without skipping to thank u
My sir says asymatric key is faster than symatric I can't understand how...?
Encryption key hoti hai vo always decryption key ki reverse hi hogi na to public key ki oposite private hogi. To agar public key sab ko pata hoga to uska reverse karke attack kr sakta hai n. ?
Jo kaam mere sir 6 months Mei nhi krr paye wo aapne 8 min Mei krr Diya.... You are genius sirr😊😊
A ki public key sabke pass ho sakte hai to kya B ki public key sabke pass nahi jo sakta?? How case four is justified.
ok
Sir jee hamesha asymmetrical wale me doubt tha ....ab clear ho gya
sir ap pakistan mai aa jao yaha fazul bkwass useless teachrs hen ...💔
Sir, please upload a video on polyalpabetic cryptography
thnku so much sir g ...love from pakistan ❤❤❤❤
thnk u sir...superb explanation!
Sir how public and private key are generated by each one on network
Sir plz one more leacture b upload for us I need name security artitecture
Sir....private key is meant for decryption....only ....
Sir kya public key se athuntac person khol nahi sakta
Make more tutorials on information/network security.
Bestt, best teacher , thank you sir
Sir but B ki public key to koyi bhi leh skta h koyi b message decrypt kr lega?
Sir Real life m symmetric key aur asymmetric key kha use krte hain
Sir or video banaye network par
Thank you sir... For your info... It helps me lot
