- Create printer for the permutation of bits - Update & testing the function permute_block (ok) Next Change: - Slip block in 2 blocks of 32 bits - Create function for the cycle
- Change function block-permute in des-permute - Slip the block of 64 bits in two block of 32 bits - Permute the second part of block 32 bits in 48 bits Next Change: - Slip the 48 part of block in tiny blocks of 4 bits - Permute the key of 64 bits in 56 bits and 48 bits...
- Re-write the function des_key_schedule - Create structure for the des_key - Progress in the blocks cycle [Next Change]: - Continue the des_key_schedule - Continue the blocks cycle
- Duplicate the function des_key_schedule:
