What is the equivalent of Base64.encodeToString(bytes,11) in python?

Issue

I am trying to recreate a java program in python, but I am stuck at this point

import android.util.Base64 -> this is the package

Base64.encodeToString(bytes, 11)

The python module for encoding with base64 only gets one parameter, which is bytes.

apparently, according to the android docs, the second parameter is supposed to indicate a flag, but I can't find any information about the number 11

What does this mean and how can I implement this in python?

Solution

11 is a combination of flags (or-ed together), specifically:

• NO_PADDING, which has value 1
• NO_WRAP which has value 2 and
• URL_SAFE which has value 8.

I don't know the exact way to reproduce this in Python, but I believe base64.urlsafe_b64encode gets you halfway there by implementing the equivalent of URL_SAFE. For NO_PADDING you could simply trim any trailing padding (i.e. = charcters) in the output.
