UnmarshalClientHello returns nil #298

Closed Koma358 closed 6 months ago

Koma358 commented 6 months ago

I attempted to convert the byte slice of the ClientHello message (shown below) into a struct object, but UnmarshalClientHello returned nil. The "data" value represents a valid ClientHello message. Is it possible to convert the data?

func ConvertRawbyteToObject() {
    data := []byte{22, 3, 1, 2, 0, 1, 0, 1, 252, 3, 3, 236, 27, 242, 103, 67, 86, 55, 238, 93, 214, 54, 55, 207, 230, 96, 152, 103, 172, 91, 4, 32, 213, 59, 202, 99, 222, 217, 222, 37, 238, 4, 150, 32, 118, 210, 207, 59, 192, 28, 162, 177, 106, 3, 214, 123, 68, 192, 49, 69, 113, 80, 242, 53, 207, 19, 212, 28, 91, 191, 218, 243, 244, 227, 191, 98, 0, 62, 19, 2, 19, 3, 19, 1, 192, 44, 192, 48, 0, 159, 204, 169, 204, 168, 204, 170, 192, 43, 192, 47, 0, 158, 192, 36, 192, 40, 0, 107, 192, 35, 192, 39, 0, 103, 192, 10, 192, 20, 0, 57, 192, 9, 192, 19, 0, 51, 0, 157, 0, 156, 0, 61, 0, 60, 0, 53, 0, 47, 0, 255, 1, 0, 1, 117, 0, 0, 0, 19, 0, 17, 0, 0, 14, 119, 119, 119, 46, 103, 111, 111, 103, 108, 101, 46, 99, 111, 109, 0, 11, 0, 4, 3, 0, 1, 2, 0, 10, 0, 12, 0, 10, 0, 29, 0, 23, 0, 30, 0, 25, 0, 24, 0, 16, 0, 11, 0, 9, 8, 104, 116, 116, 112, 47, 49, 46, 49, 0, 22, 0, 0, 0, 23, 0, 0, 0, 49, 0, 0, 0, 13, 0, 48, 0, 46, 4, 3, 5, 3, 6, 3, 8, 7, 8, 8, 8, 9, 8, 10, 8, 11, 8, 4, 8, 5, 8, 6, 4, 1, 5, 1, 6, 1, 3, 3, 2, 3, 3, 1, 2, 1, 3, 2, 2, 2, 4, 2, 5, 2, 6, 2, 0, 43, 0, 5, 4, 3, 4, 3, 3, 0, 45, 0, 2, 1, 1, 0, 51, 0, 38, 0, 36, 0, 29, 0, 32, 151, 38, 16, 1, 160, 225, 116, 148, 15, 242, 136, 56, 135, 206, 121, 209, 213, 184, 57, 82, 99, 85, 65, 205, 139, 121, 85, 203, 133, 194, 191, 16, 0, 21, 0, 186, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}

    result := utls.UnmarshalClientHello(data)
    fmt.Println("result: ", result)
