nodejs和java中的des/3des加密解密

Java和nodejs中des/3des加解密数据互操作，直接上代码(仅供参考)：
JS代码如下：

var assert = require('assert');  
var crypto = require('crypto');  function test_des(param) {  var key = new Buffer(param.key);  var iv = new Buffer(param.iv ? param.iv : 0)  var plaintext = param.plaintext  var alg = param.alg  var autoPad = param.autoPad  //encrypt  var cipher = crypto.createCipheriv(alg, key, iv);  cipher.setAutoPadding(autoPad)  //default true  var ciph = cipher.update(plaintext, 'utf8', 'hex');  ciph += cipher.final('hex');  console.log(alg, ciph)  //decrypt  var decipher = crypto.createDecipheriv(alg, key, iv);  cipher.setAutoPadding(autoPad)  var txt = decipher.update(ciph, 'hex', 'utf8');  txt += decipher.final('utf8');      assert.equal(txt, plaintext, 'fail');  
}  test_des({  alg: 'des-ecb',  autoPad: true,  key: '01234567',  plaintext: '1234567812345678',  iv: null  
})  test_des({  alg: 'des-cbc',  autoPad: true,  key: '01234567',  plaintext: '1234567812345678',  iv: '12345678'  
})  test_des({  alg: 'des-ede3',    //3des-ecb  autoPad: true,  key: '0123456789abcd0123456789',  plaintext: '1234567812345678',  iv: null  
})  test_des({  alg: 'des-ede3-cbc',    //3des-cbc  autoPad: true,  key: '0123456789abcd0123456789',  plaintext: '1234567812345678',  iv: '12345678'  
})
