Write the program to implement the following tasks:

$1-$ Given a random plaintext block and a random key, find the $64-$bit Ciphertext $($the

output of the DES encryption$)$

Plain Text: $1$F$3$A$56$ABCD$133537$ Key: $5$A$899277$E$4798$D$78$

$2-$ Given the output of part $1,$ find the $64-$bit plaintext $($the output of the DES

decryption$)$

Do the first $3$ rounds by hand and submit the results.

Note: You may use any programming language.

Please submit your code and screenshot of the output with instructions on how to use

your program. Show the output of each round in your screenshots, it should be in the

following format for both encryption and decryption:
