Are The values of the table fixed or changeable?

Why there is an extra xor operation after the transposition?

there's already one in in that DES series

A lot of things here confuses me : In the key generation side there should be Left Half Key i-1 instead of Left Half i-1, also in the bottom there should be Left Half Key i, Right Half Key i instead of Left Half Key i-1, Right Half Key i-1. Also you didn't mention Permuted Choice 1 block that takes 64 bits and converts them to 56 bit which when divided into two parts (28 bits each) should be then left shifted, so your mention of 32 bit key inputs being left shift is also wrong. Also I didn't understand the Right Half i-1 block below the Transposition block because as far as I know we directly XOR the output of Transposition Block with left half of plain text so why did you mention that?

Suggest another video please. I came to the comment section because of this problem.

hmm so the 64 bit key is permuted first thats p 1 then splitted 32 32 bits which go left shifts, then the permuted choice 2 which gave 48 bits forming the round key used edit: oh i get what ur saying now doing p1 should hav given 56 bits as per the previous video. hmm idk
