    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.

    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 :(

    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?

  • @sword013
    @sword013 5 років тому +1

    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

      @sundeepsaradhi  6 років тому

      that was actually done in PGP
      Compression followed by encryption.

    • @keshavkashyap166
