Hex

Hex is an encoding method that converts binary data to ASCII characters, using 16 characters (0-9, A-F) to represent data. dongle supports standard Hex encoding, also known as Base16 encoding.

Encoding Data

Input Data

// Input string
encoder := dongle.Encode.FromString("hello world").ByHex()

// Input byte slice
encoder := dongle.Encode.FromBytes([]byte("hello world")).ByHex()

// Input file stream
file, _ := os.Open("test.txt")
encoder := dongle.Encode.FromFile(file).ByHex()

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

Output Data

// Output string
encoder.ToString() // 68656c6c6f20776f726c64
// Output byte slice
encoder.ToBytes()  // []byte("68656c6c6f20776f726c64")

Decoding Data

Input Data

// Input string
decoder := dongle.Decode.FromString("68656c6c6f20776f726c64").ByHex()

// Input byte slice
decoder := dongle.Decode.FromBytes([]byte("68656c6c6f20776f726c64")).ByHex()

// Input file stream
file, _ := os.Open("test.txt")
decoder := dongle.Decode.FromFile(file).ByHex()

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

Output Data

// Output string
decoder.ToString() // hello world
// Output byte slice
decoder.ToBytes()  // []byte("hello world")
