why wasn't stuff auto-paded?

[deostroll]

Hi,

Below is simple code:

=== START

from Crypto.Cipher import AES
import os
import base64

key = 'This is a key123'
print('key length =', len(key))
iv = 'This is an IV456'
print('iv length =', len(iv))
message = "The answer is no, but greater than 16 charaters"
print('message length =', len(message))

=== END

This obviously errored saying ValueError: Data must be padded to 16 byte boundary in CBC mode

So why was this api not doing the padding? Or is it that padding is a subjective topic dependent on business logic? Are there apis that do autopad?
