Java代码：

public String encryption(String str)throws Exception{
		try {
			String KEY = "123456789";
			byte[] enCriptSHA1String = enCriptSHA1(str);//SHA-1   
		    String base64String = enBase64(enCriptSHA1String);//
		    System.out.println("1    "+base64String);
		    System.out.println("1.5    "+(str + "_" + base64String));
		    byte[] enCrptString = enCrpt((str + "_" + base64String).getBytes(), KEY.getBytes());//DESede 
		    String base64StringRe = enBase64(enCrptString);
		    System.out.println("2    "+base64StringRe);
		    str=URLEncoder.encode(base64StringRe);
		    System.out.println("3    "+str);
		} catch (Exception e) {
			throw e;
		}
		return str;
	}
	public byte[] enCriptSHA1(String authenticator){
		//加密的方式
		final String Algorithm = "SHA-1";
		//实例MessageDigest对象
		MessageDigest md=null;
		byte[] encode=null;
		//加密数据转换成字节
		byte[] bt=authenticator.getBytes();
		try {
			//SHA-1加密
			md=MessageDigest.getInstance(Algorithm);
			md.update(bt);
			//二行制到字符串的转变
			encode=md.digest();
		} catch (NoSuchAlgorithmException e) {
			e.printStackTrace();
		}
		return encode;
	}
	public byte[] enCrpt(byte[] reqStr ,byte[] enkey){
		//加密的方式
		final String Algorithm = "DESede";
		//加密后的数据
		byte[] encoded = null;
		//根据密钥加密对象
		Cipher cipher = null;
		//得到密钥
		SecretKey secretKey = null;
		try {
			//得到密钥
			secretKey = getSecretKey(enkey,Algorithm);
			//加密
			cipher = Cipher.getInstance(Algorithm);
			cipher.init(Cipher.ENCRYPT_MODE, secretKey);
			//得到解加密后的数据
			encoded = cipher.doFinal(reqStr);
		} catch (Exception e) {
			
		}
		return encoded;
	}

nodejs 代码：

function aesEncrypt(data) {
		 var cipher = crypto.createHash('sha1');
		 var encodeC = cipher.update(data).digest().toString('base64');
		 var ciphertwo = crypto.createCipher('des-ede',new Buffer('12345678'),0);
		 var endate = data+'_'+encodeC;
		 var en = ciphertwo.update(new Buffer(endate),'binary','base64')+ciphertwo.final('base64');
		 console.info("en: "+en+"   ");
         return en;
	};

以上分别是我java和nodejs加密写法，为什么得出的结果不一样呢请大神指导下，看看哪里有错。
