AttributeError: 'bytes' object has no attribute 'translate'

[magixyu]

When use the below code, the error apears:
base64.b32decode(activation_code, True, "I")

Traceback (most recent call last):
File "", line 1, in
File "onepass.py", line 90, in get_next_code
File "onepass.py", line 57, in _get_entropy
File "base64.py", line 269, in b32decode
AttributeError: 'bytes' object has no attribute 'translate'

it looks that the base64 module in micropython-lib is not compatible. Please help to take a look of this issue.

Thanks,
Tristan

Thanks @magixyu -- I think this was inherited from the original version of this repo and clearly this code has just been copied from CPython. We should probably remove it until it can be re-implemented.

On most boards you should be able to use the built-in binascii for basic base64 encode/decode via binascii.b2a_base64 and binascii.a2b_base64.

@jimmo
Thank you very much for the information and suggestions. In my code, it is calling the base32 decoding which is calling bytes.translate.

I created a pull request(#768 ) just for base64 module. Please help to review.

Thanks,
Tristan

Tested on esp32s3. The module base64 works well.
