This format is way better than the others in the playlist. Please continue this way(pen and paper) rather than writing on a sheet. There's a noticeble audio difference as well. Thanks!

Hi mam, I want to tell you that, you are teaching wrong, from 6:17 to 6:24 , the actual process that is done in Initial permutation is, " The initial permutation is performed on plain text. Next, the initial permutation (IP) produces two halves of the permuted block; saying Left Plain Text (LPT) and Right Plain Text (RPT). Now each LPT and RPT go through 16 rounds of the encryption process. The result of this process produces 64-bit ciphertext ". And the 64-bit size ciphertext and 48-bit size key is given as an Input to Round 1 and same for all the rounds Thank you. please pin this comment if the written text is correct maybe this could help any student to understand the actual process. 🙂🙂🙂🙂🙂🙂
