      Hi to everyone.

      I try to create a cipher using AES in CTR mode.

      from crypto import AES
      import crypto
      
      key = b'notsuchsecretkey'
      counter = crypto.getrandbits(128)
      cipher = AES(key, AES.MODE_CTR, counter)
      

      but I receive the following Error:

      Traceback (most recent call last):
        File "<stdin>", line 1, in <module>
        File "crypt.py", line 6, in <module>
      TypeError: object with buffer protocol required
      

      AES.MODE_CFB works well.

        @Innocenzo said in AES CTR Mode on WiPy 2.0:

        cipher = AES(key, AES.MODE_CTR, counter)

        change it to:

        cipher = AES(key, AES.MODE_CTR, counter=counter)
        

        think about people first, then computers
