In the figure, each character, both lowercase (plaintext) and uppercase (ciphertext) characters, is assigned an integer value mod26 (not ASCII). The encryption algorithm used is to add the text text value to the key used. Meanwhile, the decryption algorithm used is subtracting the ciphertext value from the key used. All values ​​are expressed in integer mod26 (0-25).   If key = 20 is used, encrypt the plaintext of your First Name

Description i What is timestamp? Note that we have only timestamps, which ALWAYS contain yyyy-mm-dd as a date, hh:mm:ss as a time, and +/-zzzz as a timezone. time 2017-10-14 00:11:20 +0000 date time zone 12345 + timeconverter.py 1 def convert_time(timestamp): #NOTE: COMPLETE THE CODE FROM HERE! 6 #DO NOT MODIFY THE CONTENT HERE: 7 def print_result(hour, minute): 8 9 print("The time is {}:{}".format(hour, minute)) 10 #DO NOT MODIFY THE CONTENT HERE: 11 timestamp_list = ['2017-10-14 00:11:20 +0000', 12 '2022-03-24 07:22:16 -0400' Topic: Timestamp Converter Write a program timeconverter.py that has two functions: 1) The function convert_time : for extracting the hour and minute from a timestamp and 2) The function print_result: for printing the results. Note that the two functions should be called under the loop. 1) The function convert_time should: 1. take the timestamp from the function call, 2. separate time from date and time zone, 3. split it into hour, minute and seconds, 4. extract…
