NETWORK SECURITY - PGP (E-MAIL SECURITY) 

thanks to you … best explanations for PGP email security on RU-vid.

Order of Operations -> A digest is created from the message and encrypted using the private key of Sender --> The message is compressed --> the message(compressed) along with the digest are encrypted using the shared session key of the sender and receiver --> the encrypted(message and digest) are send along with the shared session key of sender and receiver which itself is encrypted with the public key of the receiver.

Sir you have helped me a lot sir during my exams time. Your explonation is very goood and clear. Keep maintian that sir. You are one of the best teacher in my study career. I was scared about this subject and i found you on youtube. Now i learned lot of subject. Thank you very much sir.

Sir i want -> "Secure/Multipurpose Internet Mail Extensions" (S/MIME)...plse upload the lecture on S/MIME...

Very good explanation of the concepts, showing print out at the end was good too, please keep up this good work of sharing knowledge

Excellent explanation, thank you very much for sharing your knowledge with us! I just have one question, if the secret key is sent to the recipient in an encrypted form, using an asymmetric encryption algorithm (Public-key Encryption). Where does Diffie Hellman really apply? I don't see it :(

Thank you very much sir for the tutorial,The concept was presented very well so that I could understand it easily and was able to attend this question succesfully for my university exam...

Thank for such a good Explanation!

Can't get better explanation of PGP that this. Damn good.

Excellent job... sir... thank you sir for full details of PGP....

Thank you sir. Your videos helped me a lot in my semester exams.

s/mime video please

sir i saw your all lectures of ins,sir your explanation technique is awesome,i can easily understand the concepts.

Nice one! Simplified the logic. But in this video, you are doing decryption and then verifying signature. I think whoever wants to decrypt, first check the signature and then they would decrypt. Any suggestion to achieve that?

Thank you that was a pretty good tutorial.

Thanks sir, you are awesome. your videos are amazing.

Thank you so much Sir Lecture help me a lot to clear my concepts 🤘

Thankyou so much for your neat and clear explanation sir

what a explanation nice very simple understanding sir very very nice

thank you,you made it so simple to understand

Your classes are very helpful thanks alot

Thanks for your explanation i have one doubt what is the purpose of we using compression and decompression?

Very good explanation.. thanks

Tq sir, your explanation is very clear and understandable plz give explanation of rc4 and a5 encryption algorithm plzzz

Crystalline clear explanation

can someone give an intuition on how the decryption of the "private key encrypted message" using the public key gives the message?

When plain text appended with digest what is a need of digest receive can read that plain text easily

Struggling with pgp really helpful thank you so much sir

Excellent lecture...will u plzz upload a video on S/MIME..I have an exam...

Thanks sir for great explanation i have exam after 2 days and you save my time 😊

Kind hearted Human being

really love your explanation

Sir your lecture on PGP is pretty good and understandable...along with PGP ,we need S/MIME...if possible plse upload the lecture on S/MIME...

Thank you so much.

NICE SUPER EXCELLENT MOTIVATED

It's really helpful sir.. Thanks alot

No need to read text books cause of you sir :)

Your teaching techniques is very good It's my humble request please upload little bit short video

At sender side u encrypted the hash but at receiver side you didn't decrypt the hash function ??

Tnx for makin it so simple.👌👌

thankyouu so much sir , it was just outstandingg thankyou

Sir your channel was really very helpful to me and my friends as well thank you very much sir i wrote my exam well because of you.

Thanks sir! U saved me!

i passed my CNS subject because of you sir

Hi sir Very nice explanation sir Want ur video on minme and s/mime

Sir how you use piblic key for decryption as per my knowledge we can only use private key for decrypt the message and public key is use for encrypt the message.....

On some websites i read that session key is also generated to encrypt the message and then the session key is encrypted by the reciever's public key. But you didn't talk about session key. I am very confuse that session keys are required for pgp or not. Please reply me. I am waiting.

Excellent Video Sir.

Thank you so much sir .you helped me lot .

Which hash function is used, do these double (II) mean logical „or“-Operator? Thanks for this Video my friend 👍👍

A very good lecture Sir.

Nice video. All clear

Very nice explanation sir...

Thank You So Much

Nice explanation sir ❤❤❤

how we are getting symmetric key ? is that from User A private key or User B`s public key ? Please confirm.

Sir becoz of your sessions, I'm much able to understand things which i can't do so from reading books.... Thankyou very much can you add videos on how to prepare for on campus placement and interview

Legend 🙌

Sir please upload the lecture on S/MIME alsoooo

Superb explanation

Hello. there is wrong small problem.puplic key und private key should be swaped.puplic key just for encryption.

sir upload videos on x.509 authentication , public key infrastructure and s/SIME at an earliest. since end semester examination is nearing sir

U r just amazing sir 😍😍😍😍😍

owesome man great work

could u please tell how it is vulnerable to middle attack and how it can be solved

Sir pls clear the difference between public key encryption , digital signature and asymmetric encryption

hey, will the integrity of the message be affected if we compress the message?

THANK YOU SIR!!!!!!1

is this from Network Security Essentials by william stallings ?

your a huge talant person

PGP concept you are mentioning 3 services like authentication,confidentiality and Digital signature. But Digital signature is used to provide the Authentication service Sir. I do not know perfectly. I hope its true according to my knowledge. Please once check and respond sir. Thank You and sorry if any thing wrong from my side Sir.

god bless youu

sir where do we use algorithms here cacn u show in diagram please

Did u have any material for this subject sir.if yes u can provide materials in website or provide link in description

WOW!

Pretty good lecture

Thax sir it is very usefull for me

Thank you sir

excellent

Really nice video sir

thanks

Thankyou sir

is PGP working on Asymmetric Key ??

Dear sir, please give in depth explanation of any new term say " compatibility in PGP" why it is required , how to incorporate it .

sir plz upload x509 certification, cant find anywhere .......!!!, actually i am having exam tmro

sir,please upload IDEA algorithm

super sir i have shared to my friends

Please upload Secure/Multipurpose Internet Mail Extensions (S/MIME) Video

Sir aapke video bahoot accha hai..but thode short mein bataynge to aapko jyada views bhi mil sakte hai...

Cool stuff sir ! But is that really diffi exchange ? We are not really generating keys. That Ks is our value , its not getting generated and on the receivers side, its getting dectypted ,not generated. Idk if its a valid doubt.. But Cool

how to like all your videos in a single shot.. its difficult to like every video

Please explain the concept s/mime

Thanks sir...

Sir upload vedios X.509authentication services ,public key infrastructure .

Please upload the last diagram paper in the description box or comment box sir

What are the books i will read ugc and pgtrb net exam plz refer

❤️❤️

Very nice explanation . Guess Session key is Ks

sir,board clear ga ledu,its not visible clearly.

btw why are we compressing the message and then encrypting? why isn't the message directly encrypted?
