使用Bouncy Castle和Node.js加密时会产生不同的结果

Question

我正在尝试使用Java（使用Bouncy Castle）和Node.js执行相同的加密操作，但是我在每种语言中都会收到不同的结果。以下是我尝试的实施 - 有人能找到我出错的地方吗？

Java代码

//Java code:
import org.bouncycastle.crypto.engines.DESedeEngine;
import org.bouncycastle.crypto.params.KeyParameter;
import org.bouncycastle.crypto.*;
//...
String inputString = "24778721";  //8 bytes
String keyString = "lf9aodkflaen7;ad";
BufferedBlockCipher cipher = new BufferedBlockCipher(new DESedeEngine());
byte[] key = keyString.getBytes();
byte[] input = inputString.getBytes();
cipher.init(isEncode, new KeyParameter(key));       

byte[] result = new byte[cipher.getOutputSize(input.length)];       
int outputLen = cipher.processBytes(input, 0, input.length, result, 0);
cipher.doFinal(result, outputLen);

//result is "65dcbb2e08e6d66e"

JavaScript代码

//node.js
var crypto = require('crypto');
var key = "lf9aodkflaen7;ad";
var data = "24778721";
var keybuf = new Buffer(key);
var databuf = new Buffer(data);

var cipher = crypto.createCipher('des-ede', keybuf);
cipher.update(databuf);
var result = cipher.final();

// result is "bf d2 cc 51 c5 e9 ef 38"

替代使用createCipheriv函数：

var cipher = crypto.createCipheriv('des-ede', keybuf.toString("binary"), '');
cipher.update(databuf);
var result = cipher.final();

// result is  "7a 24 bf 56 04 18 e3 6a"

第二次尝试时差不多了。此代码将为您提供与Bouncy Castle相同的值：

//node.js
var crypto = require('crypto');
var key = "lf9aodkflaen7;ad";
var data = "24778721";
var keybuf = new Buffer(key);
var databuf = new Buffer(data);

var cipher = crypto.createCipheriv('des-ede', keybuf, '');
var crypted = cipher.update(databuf, 'utf8', 'hex');

console.log(crypted);
//65dcbb2e08e6d66e
