Node.js中AES加密和其它語言不一致問題解決方案_javascript技巧

例子一：

這幾天被一個問題困擾著。 Nodejs的AES加密和Java，C#加密出來的不一致。當然，這樣就不能解密了。糾結了許久：後來還是實在不行了，看了下原始碼，要不然還得繼續糾結下去。網路上說，通常的nodejs AES和其他語言實作不一樣。好~~或許吧。
nodejs的crypto模組。

複製程式碼 程式碼如下:

var crypto = require('crypto') ;

    var data = "156156165152165156156";
    console.log('Original cleartext: ' data);
  8541561566';
    var clearEncoding = 'utf8';
    //var cipherEncoding = 'hex';
    //If the next line is uncommented, the fipan> an 素🎜>/*加密*/
    var cipher = crypto.createCipher(algorithm, key);

    var cipherChunks = [];
    cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding));

H . sole.log( cipherEncoding ' ciphertext: ' cipherChunks.join(''));

/*解密*/
    var decipher = crypto.createDecipher(algorithm, key);
= var (var i = 0;i       plainChunks.push(decipher.update(cipherChunks[i], cipherEncoding, clearEncoding));

    }
    plainChunks.push(decipher.final(clearEncoding));
    console.log("UTF8 plaintext deciphered: "YChunks.join(''l.錯~~加密解密成功。但是和java，C#中加密出來的不一樣。神啊。我想，大家都在這裡糾結著吧~~對不對。其實只要加個向量，就可以和一致了。網路上搜尋出來的資源太少。才讓自己糾結那麼久。好吧，
正確代碼是：

複製代碼
代碼如下:

var crypto = require('crypto');     var data = "156156165152165156156";    console.log('Original cleartext: ' data);  8541561566';

    var clearEncoding = 'utf8';

    var iv = "";
    //var cipherEncoding = 'hex';    //var cipherEncoding = 'hex';

    //var cipher恩>    var cipherEncoding = 'base64';
    var cipher = crypto.createCipheriv(algorithm, key,iv);

    var cipherChunks = [];
    cipherChunks.push(cipher.update(data, clearEncoding, cipherEncoding));
H . sole.log( cipherEncoding ' ciphertext: ' cipherChunks.join(''));

    var decipher = crypto.createDecipheriv(algorithm, key,iv);
    var plainChunks = [];
    for (var i = 009.p. s. push(decipher.update(cipherChunks[i], cipherEncoding, clearEncoding));

    }
    plainChunks.push(decipher.final(clearEncoding));
    console.log("UTF8 plaintext deciphered: "Hyk 使用，加密出來是一致的。好吧，結貼~~~我討厭你，浪費了我一天。

範例二：

工作上遇到nodejs端透過aes加密，安卓客戶端java解密，同意nodejs也需要解密安卓客戶端加密過來的內容，發現兩個加密結果不一樣，查詢資料發現java端需要對密鑰za再MD5加密一遍，以下是aes ecb加密的內容，如果是cbc也同樣需要對秘鑰MD5加密：

nodejs:

複製程式碼

程式碼如下:

/**
 * aes加密
 * @param data
 * @param secretKey
 */ 
encryptUtils.aesEncrypt = function(data, SecretKey) { 
    var cipher = crypto.createCipher('aes-1283); 
    return cipher.update(data,'utf8','hex') cipher.final('hex'); 
} 

/**
 * aes解密
 * @param data
 * @param secretKey
 * @returns {*}
 */ 

/***/ 
encryptUtils.aesDecrypt = function(data, SecretKey) { 
    var cipher = crypto.create.煞）； 
    return cipher.update(data,'hex','utf8') cipher.final('utf8'); 

} 

javajavajava複製程式碼

程式碼如下：

套件com.iofamily.util; 

導入java.security.MessageDigest; 

導入javax.crypto.Cipher;ret

導入javax.Secypto.Cipher;ret
