title: Looking for a C# hash faster then MD5 or SHA256
body: <p>I am trying to find something potentially faster then SHA256. I have over 1 billion records I need to hash and verify if they are unique. I am currently running it through an MD5 which seems pretty fast then through the sha256 to avoid collisions. Running them in that order seems to give me a little performance boost but I still need it faster. I am looking for the names or examples of some hashes done in c# or some pseudo-code so I can recreate it in c#.</p>
