    Hi,
    Big fan of your video,
    I have a small doubt,what are round constant and how are they calculated?

  • @ishaqahmad
    @ishaqahmad 6 месяцев назад

    Its an amazing and excellent explanation. I have one question that is for round 1 you have selected round constant 1 in the constant table, for round 2 you have written round constant 2 then why not for round 3 the round constant should be 3 and for round 4 should have round constant 4 while there is 4 for round 3 and for round 4 is a round constant 8

    Last state matrix has errors....if we do xor between message and expanded key we get below output
    0, 16, 1a, 17
    4, 1c, 0, 7
    17, e, 3, 1
    1b, f, 8, 10
    In the last line instead of 8 your video shows 0f...i think that is wrong....can you check and correct it?

    How words are converted to binary form

    • @md.shadab7208
      @md.shadab7208 11 месяцев назад

      Each word consists of 4 bytes. Each byte of a word is represented in a hexadecimal form. The rule of conversion of hexadecimal to binary is, take each character of a hexadecimal number and convert that into a 4 bit binary number. I hope you know how to convert hexadecimal to binary.

    @knowledgepeace4848 2 года назад +2

    A great explanation, thank you. I wonder if you could explain the key size 192-bit. The 128-bit key fits into a 4 by 4 block but what about a 192-bit key? Do we still use a 4 by 4 block? And if so, what happens to the remaining bits? I know I am of missing something but don't know what.
