Hmac-Sm3

Hmac-Sm3 is a message authentication code algorithm based on sm3. dongle supports standard and streaming sm3 message authentication code algorithms and provides multiple output formats.

Note: The WithKey method must be called before BySm3

Input Data

// Input string
hasher := dongle.Hash.FromString("hello world").WithKey([]byte("dongle")).BySm3()
// Input byte slice
hasher := dongle.Hash.FromBytes([]byte("hello world")).WithKey([]byte("dongle")).BySm3()
// Input file stream
file, _ := os.Open("test.txt")
hasher := dongle.Hash.FromFile(file).WithKey([]byte("dongle")).BySm3()

// Check HMAC error
if hasher.Error != nil {
	fmt.Printf("HMAC error: %v\n", hasher.Error)
	return
}

Output Data

// Output hex-encoded string
hasher.ToHexString() // 8c733aae1d553c466a08c3e9e5daac3e99ae220181c7c1bc8c2564961de751b3
// Output hex-encoded byte slice
hasher.ToHexBytes()  // []byte("8c733aae1d553c466a08c3e9e5daac3e99ae220181c7c1bc8c2564961de751b3")

// Output base64-encoded string
hasher.ToBase64String() // jHM6rh1VPEZqCMPp5dqsPpmuIgGBx8G8jCVklh3nUbM=
// Output base64-encoded byte slice
hasher.ToBase64Bytes()  // []byte("jHM6rh1VPEZqCMPp5dqsPpmuIgGBx8G8jCVklh3nUbM=")

// Output raw string
hasher.ToRawString()
// Output raw byte slice
hasher.ToRawBytes()
