I agree. This encoding seems to be a micro-optimisation with no real
justification. I'd prefer to see hexdigest used, as (a) it means md5
is not a special case, and (b) there's not a proliferation of 1-line
functions in use code doing that b64encode/strip dance.

With hexdigest, the syntax is just [algorithm=]hexdigest, where
algorithm defaults to md5. Much simpler to describe and work with.

Paul.
