Quick question... Why would you want to?

I suspect you might be trying to fix a problem you don't have. Sure, weaknesses 
have been found in md5, but those relate to collitions, not backtracking to 
find what was hashed. The weaknesses can be used to make a hash over something, 
have the hash signed, and then replace what was hashed, with the hash being 
identical, and thus making it possible to make falsified ssl certificates and 
similar. 

Those attacks do not break http digest auth.

everything about md5)
