Nodejs AES加密

这几天被一个问题困扰着。

Nodejs的AES加密和Java，C#加密出来的不一致。当然，这样就不能解密了。

纠结了许久：后来还是实在不行了，看了下源代码，要不然还得继续纠结下去。

网上说，通常的nodejs AES和其他语言实现不一样。好吧~~或许吧。

nodejs的crypto模块。

var crypto = require('crypto'); var data = "156156165152165156156";
console.log('Original cleartext: ' + data);
var algorithm = 'aes-128-ecb';
var key = '78541561566';
var clearEncoding = 'utf8';
//var cipherEncoding = 'hex';
//If the next line is uncommented, the final cleartext is wrong.
var cipherEncoding = 'base64';
/*加密*/
var cipher = crypto.createCipher(algorithm, key); var cipherChunks = [];
cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding));
cipherChunks.push(cipher.final(cipherEncoding));
console.log(cipherEncoding + ' ciphertext: ' + cipherChunks.join(''));
/*解密*/
var decipher = crypto.createDecipher(algorithm, key);
var plainChunks = [];
for (var i = 0;i < cipherChunks.length;i++) {
plainChunks.push(decipher.update(cipherChunks[i], cipherEncoding, clearEncoding)); }
plainChunks.push(decipher.final(clearEncoding));
console.log("UTF8 plaintext deciphered: " + plainChunks.join(''));

的确，没错~~加密解密成功。但是和java，C#中加密出来的不一样啊。神啊。

我想，大家都在这里纠结着吧~~对不对。其实只要加个向量，就可以和一致了。网上搜索出来的资源太少。才让自己纠结那么久。好吧，正确代码是：

var crypto = require('crypto'); var data = "156156165152165156156";
console.log('Original cleartext: ' + data);
var algorithm = 'aes-128-ecb';
var key = '78541561566';
var clearEncoding = 'utf8';
var iv = "";
//var cipherEncoding = 'hex';
//If the next line is uncommented, the final cleartext is wrong.
var cipherEncoding = 'base64';
var cipher = crypto.createCipheriv(algorithm, key,iv); var cipherChunks = [];
cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding));
cipherChunks.push(cipher.final(cipherEncoding));
console.log(cipherEncoding + ' ciphertext: ' + cipherChunks.join('')); var decipher = crypto.createDecipheriv(algorithm, key,iv);
var plainChunks = [];
for (var i = 0;i < cipherChunks.length;i++) {
plainChunks.push(decipher.update(cipherChunks[i], cipherEncoding, clearEncoding)); }
plainChunks.push(decipher.final(clearEncoding));
console.log("UTF8 plaintext deciphered: " + plainChunks.join(''));
