Hmac-Sha1

Hmac-Sha1 is a message authentication code algorithm based on sha1. dongle supports the standard sha1 message authentication code algorithm and provides multiple output formats.

Note: The WithKey method must be called before BySha1

Input Data

// Input string
hasher := dongle.Hash.FromString("hello world").WithKey([]byte("dongle")).BySha1()
// Input byte slice
hasher := dongle.Hash.FromBytes([]byte("hello world")).WithKey([]byte("dongle")).BySha1()
// Input file stream
file, _ := os.Open("test.txt")
hasher := dongle.Hash.FromFile(file).WithKey([]byte("dongle")).BySha1()

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

Output Data

// Output Hex encoded string
hasher.ToHexString() // 91c103ef93ba7420902b0d1bf0903251c94b4a62
// Output Hex encoded byte slice
hasher.ToHexBytes()  // []byte("91c103ef93ba7420902b0d1bf0903251c94b4a62")

// Output Base64 encoded string
hasher.ToBase64String() // kcED75O6dCCQKw0b8JAyUclLSmI=
// Output Base64 encoded byte slice
hasher.ToBase64Bytes()  // []byte("kcED75O6dCCQKw0b8JAyUclLSmI=")

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