There was a proposal that floated around that defined an extended fingerprint to be an algorithm number followed by the actual bits.

For example, ASCII-fied 23:ABCDEF0123...FF. There's an obvious binary representation. There's an obvious way to truncate that as well -- just decide if you truncate little-endian or big. (Personally, despite being a little-endian bigot, this is a place where network byte order is even to me the obvious win.)

The major advantage of this is that you can define it and then you never have to change it again. We don't have to have any arguments over what hash function is proper to use, etc. An implementation can decide to support or not support whatever.
