What is the output of the first round of the DES algorithm when the first and last bits of plaintext’ and the key bits are ones, and the remaining bits are zero? Show your work (How to generate keys and each step until the output of the first round). (4 points)

1) What is the output of the first round of the DES algorithm when the first and last bits of plaintext’ and the key bits are ones, and the remaining bits are zero? Show your work (How to generate keys and each step until the output of the first round). (4 points)

64 bits input: 100…..01

56 bits key: 100….01

solve that
