Mention in the collector that the padding that's incorrect doesn't
refer to spaces, but to equal signs. The ASCII representation of
base64 is in sets of 4 characters, which translate to 3 bytes. If the
ASCII data is of a length that doesn't evenly divide by 4, the string
is supposed to end with equal signs as "padding". If it doesn't,
you'll get the "incorrect padding" error.
Incidentally, try the following:
base64.decodestring('basic===')
This products gibberish, but it does work. :-)
