SECRET_MESSAGE = string_to_binary ( "THISISAFAKEMESSAGEYOUNEEDTOUSETHEOUTPUTTOGETTHEREALSECRETMESSAGE" )
alphabet = "01"
assert all ([ char in alphabet for char in SECRET_MESSAGE ]) # makes sure the only characters in the secret message are in the alphabet
key = os . urandom ( 16 ) # generate a random key
cipher = AES . new ( key , AES . MODE_ECB ) # defines the AES cipher using ECB mode
for char in SECRET_MESSAGE : # encrypt the secret message character by character
print ( cipher . encrypt (( char + " \x00 " * 15 ). encode ()). hex ()) # encrypt the character using AES-ECB mode
