    Unlike urlparse.parse_qsl(..., strict_parsing=True) urldecode will enforce
    correct formatting of the query string by validation. If validation fails
    a ValueError will be raised. urllib.parse_qsl will only raise errors if
    any of name-value pairs omits the equals sign.

    OAuth (1 and 2) does not specify the format of tokens except that they
    should be strings of random characters. Tokens should not be guessable
    and entropy when generating the random characters is important. Which is
    why SystemRandom is used instead of the default random.choice method.
