Functions ¶
func New ¶
New returns a new hash.Hash computing the SM3 checksum. The Hash also implements encoding.BinaryMarshaler and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.
Example ¶
package main
import (
"fmt"
"github.com/emmansun/gmsm/sm3"
)
func main() {
h := sm3.New()
h.Write([]byte("hello world\n"))
fmt.Printf("%x", h.Sum(nil))
}
Output: 4cc2036b86431b5d2685a04d289dfe140a36baa854b01cb39fcd6009638e4e7a
Example (File) ¶
package main
import (
"fmt"
"io"
"log"
"os"
"github.com/emmansun/gmsm/sm3"
)
func main() {
f, err := os.Open("file.txt")
if err != nil {
log.Fatal(err)
}
defer f.Close()
h := sm3.New()
if _, err := io.Copy(h, f); err != nil {
log.Fatal(err)
}
