Hi!
While looking at the bitCount() thing I mentioned in the other thread, I noticed that Des3DkCrypto and DigestMD5Base are using a very inefficient implementation of setParityBit(). The one from DESKeyGenerator is much better and uses Integer.bitCount(), which could benefit from a population-count intrinsic.
Should I file a CR or even propose a patch?
