IIRC, std.digest functions take ubyte[] as input, so to hash a 
uint[] I would do the following:

     void main(string[] args)
     {
         import std.conv;
         import std.digest.md;

         int[] a   = [1, 2, 3, 4, 5];
         auto  md5 = new MD5Digest();

         md5.put(a.to!(ubyte[]));

         auto hash = md5.finish();
         writeln(hash);
     }
