Can someone explain to me how safer 128's key schedule works? there are many parts that make no sense because they were not described at all in the paper (pages 3 and 5 in the pdf).
The second paragraph in part 2 is basically the same sentence 3 times. he doesnt describe how the subkeys are put together, as shown in the diagram on page 5. What does the horzonal bracket thing mean? for all i know, it is like a circuit diagram, and it is a jump of some sort. it seems to be neither add nor xor. so what is it?
also, the first bit rotation says Rotate Each Byte Right by 3 Bits, but the rest of them say Rotate Each Byte Left by 6 Bits. how does that allow for both halves to generate the same subkeys?
and yes, i know safer is not safe. im just doing this to learn how the different algorithms work
