android密码加密aes,Android上的基于密码的AES加密和CryptoJS的解密

发现问题&＃xff0c;它不是一个填充问题。

正如其他人所说&＃xff0c;它与我使用SecureRandom.getInstance(“SHA1PRNG”)的事实有关。

我更正了我的代码中的问题&＃xff0c;在Android和PBKDF2上使用CryptoJS上的PBEKeySpec生成密钥。然后&＃xff0c;只需按照相同的步骤&＃xff1a;在Android从运行代码

String Test &＃61; "Lorem ipsum dolor sit amet, ...";

String password &＃61; "test";

byte[] salt &＃61; new String("12345678").getBytes("Utf8");

int iterationCount &＃61; 2048;

int keyStrength &＃61; 256;

SecretKeyFactory factory &＃61; SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");

KeySpec spec &＃61; new PBEKeySpec(password.toCharArray(), salt, iterationCount, keyStrength);

SecretKey tmp &＃61; factory.generateSecret(spec);

Log.d("encryptString Key: ", new String(Base64.encodeBase64(tmp.getEncoded())));

Cipher c &＃61; Cipher.getInstance("AES/CBC/PKCS5Padding");

c.init(Cipher.ENCRYPT_MODE, tmp);

byte[] decrypted &＃61; c.doFinal(Test.getBytes());

decrypted &＃61; Base64.encodeBase64(decrypted);

byte[] iv &＃61; c.getIV();

Log.d("encryptString: ", new String(decrypted));

Log.d("encryptString iv:", new String(Base64.encodeBase64(iv)));

输出示例&＃xff1a;

encryptString Key:: ueTU6u4PXbm86zy&＃43;UtlQfeh55xZorA58W3fKKBypheM&＃61;

encryptString:: ii8UNoi4xG1zGC8RyzHKu6JMkxixkK7LTPxGMaCHGNk&＃61;

encryptString iv:: nwy2VHctPnXOd/rahPFiWg&＃61;&＃61;

现在我们产生一个Javascript同样PBKDF2键&＃xff0c;输入输出上面到下面示例代码&＃xff1a;

var salt &＃61; CryptoJS.enc.Utf8.parse("12345678");

var password &＃61; "test";

var keyBits &＃61; CryptoJS.PBKDF2(password, salt, {

hasher: CryptoJS.algo.SHA1,

keySize: 8,

iterations: 2048

});

var iv &＃61; CryptoJS.enc.Base64.parse("nwy2VHctPnXOd/rahPFiWg&＃61;&＃61;");

var message &＃61; CryptoJS.enc.Base64.parse("ii8UNoi4xG1zGC8RyzHKu6JMkxixkK7LTPxGMaCHGNk&＃61;");

var encrypted &＃61; CryptoJS.AES.decrypt("ii8UNoi4xG1zGC8RyzHKu6JMkxixkK7LTPxGMaCHGNk&＃61;", keyBits, {

iv: iv,

padding: CryptoJS.pad.Pkcs7,

mode: CryptoJS.mode.CBC

});

console.log(encrypted.toString(CryptoJS.enc.Utf8));

Javascript输出&＃xff1a;
