This module provides data structures and utilities common
to all implementations of OAuth.

of two-element tuples.
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.

Will successfully extract parameters from urlencoded query strings,
dicts, or lists of 2-tuples. Empty strings/dicts/lists will return an
empty list of parameters. Any other input will result in a return
value of None.

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.
