Code must be written in python

1. Write a python program A which runs on computer A. Program A reads a provided text file called Input.dat. You are first required to remove all spaces and punctuation characters from this text file and write it to a new file called Clean.dat, which should contain only lowercase letters.

2. Program A is required to generate 100 random characters which are written to a file key.dat.

3. Program A is then required to use the Vigenere cipher to encrypt the Clean.dat file with the key from the key.dat file and write the result to a file called Encrypt.dat.

4. Program A is required to send the key.dat file on a designated port for key communication, to machine B running program B. Finally, program A is required to send the Encrypt.dat file on a designated port for data communication, to machine B running program B.

5. Program B is required to accept the key.dat file on a designated port for key communication with machine A running program A. Similarly, Program B is required to accept the Encrypt.dat file on a designated port for data communication with machine A running program A.

6. Furthermore, program B is required to use the key to decrypt the Encrypt.dat file and display the result to the screen, in addition to writing it to a file called Decrypt.dat.

Include relevant documentation in your programs.

Use Socket Port = 2500 for transmission of key

Use Socket Port = 2501 for transmission of data
