Re: rsync and md4

MD4 is the fastest hash I am aware of. However, there has been some successful attacks against two rounds of MD4. Although this is not to suggest that MD4 is insecure, MD5 almost as fast (~1.3 times slower) and more secure.

I thought md5 was slower than that, but I'm only going by my (addmitedly poor) memory of some comments in the tripwire docs. I'll give it a go sometime. One annoying think about the md4 implementation that I have is that on little endian machines it byte reverses the words in the buffer its hashing so I need to make a copy of the buffer each time. Is there a version of md4 that doesn't do this? Cheers, Andrew
