Cypher text

[testlorenzospa]

Hello.

I want to encrypt a simple text (not a byte string) in AES256 CBC.
Is it possible?

In a script I use these instruction

cipher = Cipher(algorithm=AES256(cryptoKey), mode=CBC(iv))
encText = cipher.encryptor().update(b"Ciao")

But if I cange the parameter to the update method in a simple text ("Ciao", without sign "b") I get an error from python

TypeError: from_buffer() cannot return the address of a unicode object

What can I do to encrypt a simple text?

Thanks.

This is not an issue about the fernet specification.
