Encode encodes src into EncodedLen(len(src)) bytes of dst. I was able to get it in bytes format usting h.Sum(nil) and able to print out the Hash-key in %x format. Let’s see an example of a write to a file. As a convenience, it returns the number of bytes written to dst, but this value is always EncodedLen(len(src)). f.
