! The logic used in initial and final permutations is the same as in

|
! technique.
|
|
!
|
|
! The macro also loads address sbox 1 to 5 to global 1 to 5, address
|
|
! sbox 6 to local6, and address sbox 8 to out3.
|
|
!
|
|
! Rotates the halves 3 left to bring the sbox bits in convenient positions.
|

!
|
|
! Loads key first round from address in parameter 5 to out0, out1.
|
|
!
|
|
! After the original LibDES initial permutation, the resulting left
|
|
! is in the variable initially used for right and vice versa. The macro
|
|
! implements the possibility to keep the halves in the original registers.
