import hashlib

# Input parameters
invoice_number = "<invoice number of bill goes here"
epru_uct_salt = "<salt value goes here>"

invoice_number_hash_string = str.encode(invoice_number + epru_uct_salt)
invoice_number_hashed = hashlib.sha256(invoice_number_hash_string).hexdigest()

print(f"{invoice_number} -> {invoice_number_hashed}")
