That library does not appear to be doing CBC as far as I can tell.
Maybe they will agree if you use EBC instead?

According to the docs, the block size for AES is 16, not 32.  It is
the key size that can be 16, 24, or 32.  But this should just result
in extra padding, so it probably doesn't explain the discrepancy.

Stylistic note: is it really necessary to use lambda here?  For
readability, just use def.  It's worth having to hit Enter a couple
extra times.

Cheers,
Ian
