Hash-Blake2b

Hash-Blake2b is a series of hash algorithms that produce hash values of different lengths, including blake2b-256, blake2b-384, and blake2b-512. dongle supports all three hash-blake2b variants.

• Blake2b-256：Generates 32-byte hash value
• Blake2b-384：Generates 48-byte hash value
• Blake2b-512：Generates 64-byte hash value

Blake2b-256

Input Data

// Input string
hasher := dongle.Hash.FromString("hello world").ByBlake2b(256)
// Input byte slice
hasher := dongle.Hash.FromBytes([]byte("hello world")).ByBlake2b(256)
// Input file stream
file, _ := os.Open("test.txt")
hasher := dongle.Hash.FromFile(file).ByBlake2b(256)

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