It's nice and small. The encoder is just base64.urlsafeb64encode(digest).rstrip('=') But is the size difference really important? The wheel file itself is compressed, and the additional amount of space needed on installation shouldn't be a problem. The advantage of using hexdigest is that both the "classic" MD5 checksum and the new tagged checksums you propose then use the same encoding for the signature.
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.
