3DES_ECB解密

Question

我想使用3DES_DEC_ECB解密从第三方服务器收到的数据 他们也提供了输出，但我无法重现。

Key = 5E8B6E1998F421204C6576544FE1A26B44FC775982D8CE2E
InputData = 13E37073120A47D119E82545CAAF1505E3E94E5E7D8B52F3
expectedoutput = 7CB842D42F4BA3C26C8297F5B26001FB5C9FD31532CA1CB7
techniqueActual output_data=3DES_DEC_ECB(Key, InputData)          

我试过下面的代码，但没有成功

import java.security.InvalidKeyException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class Util {
public static void main(String ...x) throws NoSuchAlgorithmException,         
NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException, InvalidKeyException{
String keydata=  "5E8B6E1998F421204C6576544FE1A26B44FC775982D8CE2E";

String inputData = "13E37073120A47D119E82545CAAF1505E3E94E5E7D8B52F3";

byte[] keyByte = new BigInteger(keydata,16).toByteArray();

SecretKeySpec key=new SecretKeySpec(keyByte, "DESede");    

Cipher c = Cipher.getInstance("DESede/ECB/NoPadding");

c.init(Cipher.DECRYPT_MODE, key);

byte[] output = c.doFinal(inputData.getBytes());

String hexStr = HexString.bytesToHexString(output);
System.out.println("Decoded value : "+hexStr);

} }
