nodejs和java中的des/3des加密解密对比

直接上代码(对比结果在最后)，注意DES和DESede的区别

---

【Node.js】

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'  })
