encryption means converting plain text to cipher text public key is used for this and for this process the sender uses the recipient public key which is available to everyone and encrypts the message which gets converted to cipher and now decryption means cipher to plain text here the recipient uses his own private key to decrypt the message which is in the form of cipher back to plain text
@@dandasaisantoshreddy6388 I although agree with you brother but creation of public key should take place at receiver's side and then propogate it to others so that they can encrypt it using it ,,, but here all the keys say it public say it private are created at one side ... how is this possible?
Both public key and private key can be used for encryption. When private key is used for encryption it provides authentication as in digital signature. During this the corresponding public key is used for decryption. When public key is used in encryption it provides confidentiality. During this the corresponding private key is used for decryption.
awesome sir, please teach in colleges , you are much more qualified and better than many teachers of many colleges.
i wish i knew hindi, the outline of the algorithm is well written and is easy to follow. ..
Thank you sir this is very helpful to me in my exam.... 🙂🙂🙂
Understood well. Thank you, sir
Thank you Sir🎉
Thanks sir, Please upload for CPA and CCA, Hash Functions(Tiger hash, Gear Hash) and make a playlist
Bhai yo syllabus me h ?

Kya tum log ye padkar bitcoin ki trah koi coin bana sakte ho
Very nice, Thanks
Sir make class 12 communication technologies playlist so that we can access all the lecture easily that is been uploaded at your channel
Your voice just like a my junior 🤣...
Can anyone tell me why is it called second part of encryption not first part ?
bohot hard !!!!!
Thx sir,please sebd me coding elgamal algorithm make to java application😇

Sir , if we use number other than prime number then will it give output????
This algorithm works for prime number only
how will anna university understand in hindi Sir ?
Kya tum 1 crypto currency bana sakte ho
sir dusra page lekr smjhatey.....
sir mod kaise solve kiya h?
"a mod b" means remainder after dividing 'a' by 'b'. For ex. 16 mod 11 means remainder after dividing 16 by 11... hence 16 mod 11 = 5

Plain text S=18, now solve this u ll get the wrong answer
( a * b ) mod c = (a mod c * b mod c) mod c
you are doing encryption using public key and decryption using private key ....which is practically wrong
No, you are wrong
This is assymetric key cryptography
