    Thanks! This helped a lot. I had an idea of what IV was, but I needed an example to solidify my learning.

    Great video Bud explained it well
  • Thanks man, I was going over WPA for my CCNA and I had no idea what the hell an Initialization vector was, and they did not care to explain it.

    Thanks for the video! In this example, it means that the IV will also always be sent between client-server right? Besides the encrypted message

    Thank you! The only question I have - how receiving part will know IV? Do we send IV with message itself every time? Is IV visible for "everyone" or encrypted as well. :)? What is best practice? Thanks a lot.
  • thanks a lot but what are similarities between DES and AES plz

    supposed that i capture the encrypted message 500 with IV of 3 then resend it back to the server then I would still win the game. I just have to capture the encrypted message every time I win, it does not matter if the message is different every time I win, i just resend that encrypted message and still win. Is the IV sent along with the encrypted message? Is the IV one time use only?

    but you still need to send the IV with the encrypted message (because no one else would be able to decrypt it), right?
