nodejs和java中的des/3des加密解密

ls0398

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({
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({

　　测试环境
　　win7_64,  jdk1.6.0_29, nodejs v0.10.25
　　其他
　　使用NoPadding填充, 注意待加密的数据长度必须为8字节整数倍?
　　上面nodejs中使用的是createDecipheriv， API中还有一个crypto.createCipher(algorithm, password)从password生成key和iv?
