Python base64 :)

[georgica]

You don't need a python script to do the base64 encoding:

Here is how you do it with one line of code in bash:
BASE64URL_FORMAT=$(echo "${BYTE_ARRAY:2:-2}" | tr ',' '\n' | xargs printf "%02X" | xxd -r -ps | base64 | tr -d '=' | tr +/ -_)

Update that superior stack :)
