これは上記と同じ答えですが、Python3で動作するように変更しました。
import binascii
from Crypto.Cipher import AES
from Crypto import Random
def encrypt(passwrd, message):
msglist = []
key = bytes(passwrd, "utf-8")
iv = Random.new().read(AES.block_size)
cipher = AES.new(key, AES.MODE_CFB, iv)
msg = iv + cipher.encrypt(bytes(message, "utf-8"))
msg = binascii.hexlify(msg)
for letter in str(msg):
msglist.append(letter)
msglist.remove("b")
msglist.remove("'")
msglist.remove("'")
for letter in msglist:
print(letter, end="")
print("")
