The same L{CramMD5Credentials} will always provide the same challenge,
no matter how many times it is called.

When a valid response (which is a hex digest of the challenge that has
been encrypted by the user's shared secret) is set on the
L{CramMD5Credentials} that created the challenge, and C{checkPassword}
is called with the user's shared secret, it will return L{True}.

When an invalid response is set on the L{CramMD5Credentials} (one that

secret) and C{checkPassword} is called with the user's correct shared
secret, it will return L{False}.

When C{setResponse} is called with a string that is the username and
the hashed challenge separated with a space, they will be set on the
