Stewart.

yeah, you're right again.
sorr, I had'n the time to test as I posted the message before. that's 
why I wrote "it looks cleaner" :-(

anyhow, also the " != 0 " is needed. otherwise I get this:
Error: '=' does not give a boolean result

so, the working code is:

string MD5File(string fileName) {
        
        File file = new File(fileName, FileMode.In);
        MD5_CTX context;
        int len;
        ubyte[4 * 1024] buffer;
        ubyte digest[16];
        
        context.start();
        while ((len = file.readBlock(buffer.ptr, buffer.sizeof)) != 0)
                context.update(buffer[0 .. len]);
        context.finish(digest);
        
        file.close();
        
        return digestToString(digest);
        
}
