Question $1$ : Implement the Simplified DES $($S$-$DES$).$ Your code should have the ability to input

an $8$ bit and a $10$ bit key.

Plaintext: $"10101111"(8$ bits$)$

Key: $"11001100"(8$ bits and $10$ bits$)$

Encryption or Decryption Mode: Encryption

S$-$DES Configuration:

Number of Rounds: $2$

Key Generation Process: Using permutations and shifting

Permutation Tables: IP$,$ EP$,$ P$4,$ IP$\_$inv

S$-$boxes: S$0,$ S$1$

In python please
