(转)nodejs和java中的des/3des加密解密

Java和nodejs中des加解密数据互操作，直接上代码(仅供参考)：

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({

	autoPad: true,
	key: '01234567',
	plaintext: '1234567812345678',
	iv: '12345678'
})

test_des({
	alg: 'des-ede3',	//3des-ecb
	autoPad: true,
	key: '0123456789abcd0123456789',

test_des({
