Right now MD5 runs at 1.11 KB/s in a Mac with i7 and 8 cores :-(.

AES gives: 19,79 MB/s

Something must be very wrong with digests.

It was not the digest, but the fixed arithmetic. See this boring discussion in misc-dart:

https://groups.google.com/a/dartlang.org/forum/#!topic/misc/FhxVVywbBeo

What I'll do is to rewrite UintX probably to static functions that control overflow instead of classes. This should give a great performance boost like in AES.

In the meantime, I will upload a 0.6.1 version with patched UintX to get a better performance and make digests at least usable (though slow).

I will also create some benchmarks (in addition to tests) using the benchmark harness.
