Nope.

None.
HTTP DIGEST authentication is defined[1] to use MD5 digest.
If you have a hacked client that can support SHA1, then you can
certainly hack Tomcat to use SHA1 instead of MD5: all you have to do
is change the call to getInstance("MD5") to getInstance("SHA1").
If you are going to bother to switch from MD5 to another hashing
algorithm, you might want to pick one that is a bit stronger, like one
of the SHA2 family (e.g. SHA-512).
