Hmac-Sha2

Hmac-Sha2 is a series of message authentication code algorithms based on sha2, including sha2-224, sha2-256, sha2-384, and sha2-512. dongle supports all four sha2 message authentication code algorithm variants.

• Sha2-224：Generates 28-byte hash value
• Sha2-256：Generates 32-byte hash value
• Sha2-384：Generates 48-byte hash value
• Sha2-512：Generates 64-byte hash value

Note: The WithKey method must be called before BySha2

Sha2-224

Input Data

// Input string
hasher := dongle.Hash.FromString("hello world").WithKey([]byte("dongle")).BySha2(224)

// Input byte slice
hasher := dongle.Hash.FromBytes([]byte("hello world")).WithKey([]byte("dongle")).BySha2(224)

// Input file stream
file, _ := os.Open("test.txt")
hasher := dongle.Hash.FromFile(file).WithKey([]byte("dongle")).BySha2(224)

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