NETWORK SECURITY - PGP (E-MAIL SECURITY)

PGP - PRETTY GOOD PRIVACY
THIS IS ONE OF THE EMAIL SECURITY MECHANISM
PGP SERVICES
1. AUTHENTICATION WITH DIGITAL SIGNATURE
2. CONFIDENTIALITY
3. EMAIL COMPATABILITY
4. ZIP OR COMPRESSION FUNCTION.

[@acxd]

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.

[@arunkumarravula1719]

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.

[@AshutoshMishra-pk2mo]

[@udaykiranlopinti5771]

Very nice explanation sir...

[@chiraagmayur2707]

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

[@juan_dero]

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 :(

[@ishankvasania3372]

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

[@h.b.7190]

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

[@john-we2mz]

thankyouu so much sir , it was just outstandingg thankyou

[@pnkjthapliyal]

A very good lecture Sir.

[@netrashigwan7377]

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

[@pragyanidhi2264]

Very good explanation.. thanks

[@sword013]

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

[@j4eg3r47]

Thank you that was a pretty good tutorial.

[@neelxxx007]

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?

[@steamerSama]

A bit slow for me, but very clear, thank you!!

[@abuthahirsha2712]

Tnx for makin it so simple.👌👌

[@kitz24]

Nice video. All clear

[@kanumurimanasa6740]

Sir please upload the lecture on S/MIME alsoooo

[@aganaz]

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

[@varunmeka5625]

i passed my CNS subject because of you sir

[@dr.poornimanv2906]

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

[@RakeshVerma-yp1gw]

Excellent Video Sir.

[@doomanygf3017]

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

[@eileenrabbit3367]

thank you,you made it so simple to understand

[@samkuna3006]

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

[@vinodanand9550]

Superb explanation

[@urameshiyusuke85]

really love your explanation

[@GenAiStuff]

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

[@Manvitha-srinivasa]

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

[@Paddy0808]

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

[@sundeepsaradhi]

[@nessy3543]

Thank you so much sir .you helped me lot .

[@soumya08in]

Very nice explanation . Guess Session key is Ks

[@a.yashwanth]

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

[@vishnuvardhan1832]

Really nice video sir

[@amanshingare6815]

is this from Network Security Essentials by william stallings
?

[@sundeepsaradhi]

hi aman
yes i have prepared every thing from william stallings.

[@md.anwarali9686]

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

[@sundeepsaradhi]

hi ali
thanks for your interest towards our channel and i will definitely try to do that.

[@areeshaahmed4852]

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.

[@poonamgosavi8111]

Thax sir it is very usefull for me

[@SrikanthReddy-ik1ui]

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

[@kunalgoyal6206]

Sure sir

[@snehabalajee935]

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

[@sagarg5325]

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.....

[@babuo7682]

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

[@AdityaGupta-ei3di]

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

[@yeshwanthallampati9460]

Thanks sir! U saved me!

[@dr.shemalatha7636]

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

[@aisha8938]

Thank you so much.

[@annpearl2129]

WOW!

[@niharikasaikrothapalli592]

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

[@sundeepsaradhi]

hi Niharika
that was actually done in PGP
Compression followed by encryption.

[@keshavkashyap166]

This is used in E-mail so a large chunk of data is compressed followed by segmentation, then it is sent over a network.

[@shaikadilahamed4139]

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

[@sreejasree7427]

Thank you sir

[@sundeepsaradhi]

hi PSR
i think the brightness of the camera is more so that its not visible i think and i will correct it.

[@Abhisheksingh-ud8ht]

is PGP working on Asymmetric Key ??
