  8. Description:
  9.    - This script calculates SHA-512 hashes for every ASCII character and saves them to a file.
  10.  
  11. Functions:
  12.    - sha512sum(string):
  13.        Return the SHA-512 hash of a given string.
  14.    - calculate_ascii_sha512():
  15.        Calculate SHA-512 hashes for every ASCII character.
  16.    - save_sha512_to_file(sha512_dict, filename):
  17.        Save the SHA-512 dictionary to a file in JSON format.
  18.  
  19. Requirements:
  20.    - Python 3.x
  21.  
  22. Usage:
  23.    - Run the script to generate SHA-512 hashes for ASCII characters and save them to 'sum_ascii_sha512.txt'.
  24.  
  25. Additional Notes:
  26.    - This script may take some time to complete, depending on the speed of the system.
