CryptoJs加密在android中不起作用 [英] CryptoJs Encryption is not working in android
问题描述
我必须在Android应用中实现加密。 Web开发人员正在使用CryptoJs库。表示加密算法是AES256加密。
I have to implement encryption in android app. The web developer is using CryptoJs library. means Encryption alog is AES256 encryption.
iOS和Android平台都提供不同的字符串，并且在web上接受iOS一个。对于示例字符串应该是相同的。
Both iOS and android platforms give different strings and iOS one is accepted at web.It should be same for sample strings.
我使用下面的代码片段（有2种不同的不同功能）：
I am using below code snippets (there are 2 different diffrent functions):
private void newEnc() {
String secret = "LSC@SD2017@ps";
String cipherText = "{\"device_type\":\"iOS\",\"email\" : \"jhon@gmail.com\",\"device_id\" : \"14105DA4-CEE5-431E-96A2-2331CDA7F062\",\"password\" : \"123456\",\"device_token\" : \"B44777563552882EC3139A0317E401B55D6FC699D0AC3D279F392927CAF9B566\"}";
KeyGenerator kgen = null;
try {
kgen = KeyGenerator.getInstance("AES");
SecureRandom sr = SecureRandom.getInstance("SHA1PRNG");
sr.setSeed(secret.getBytes("UTF8"));
kgen.init(256, sr);
SecretKey skey = kgen.generateKey();
Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
SecretKeySpec skeySpec = new SecretKeySpec(skey.getEncoded(), "AES");
c.init(Cipher.ENCRYPT_MODE, skeySpec);
byte[] decrypted = c.doFinal(cipherText.getBytes());
System.out.println(Base64.encodeToString(decrypted, Base64.NO_WRAP));
// decrypted = Base64.encodeBase64(decrypted);
// byte[] iv = Base64.encodeBase64(c.getIV());
// Log.e("encryptString", new String(decrypted));
// Log.d("encryptString iv", new String(iv));
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (InvalidKeyException e) {
e.printStackTrace();
} catch (NoSuchPaddingException e) {
e.printStackTrace();
} catch (BadPaddingException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IllegalBlockSizeException e) {
e.printStackTrace();
}
}
我也用过：
private void enctest(String cipherText) {
String secret = "LSC@SD2017@ps";
// String cipherText = "{\"device_type\":\"iOS\",\"email\" : \"jhon@gmail.com\",\"device_id\" : \"14105DA4-CEE5-431E-96A2-2331CDA7F062\",\"password\" : \"123456\",\"device_token\" : \"B44777563552882EC3139A0317E401B55D6FC699D0AC3D279F392927CAF9B566\"}";
MessageDigest md5 = null;
try {
// String cipherText = "U2FsdGVkX1+tsmZvCEFa/iGeSA0K7gvgs9KXeZKwbCDNCs2zPo+BXjvKYLrJutMK+hxTwl/hyaQLOaD7LLIRo2I5fyeRMPnroo6k8N9uwKk=";
byte[] cipherData = Base64.decode(cipherText.getBytes(), Base64.NO_WRAP);
byte[] saltData = Arrays.copyOfRange(cipherData, 8, 16);
md5 = MessageDigest.getInstance("MD5");
final byte[][] keyAndIV = GenerateKeyAndIV(32, 16, 1, saltData, secret.getBytes("UTF-8"), md5);
SecretKeySpec key = new SecretKeySpec(keyAndIV[0], "AES");
IvParameterSpec iv = new IvParameterSpec(keyAndIV[1]);
byte[] encrypted = Arrays.copyOfRange(cipherData, 16, cipherData.length);
Cipher aesCBC = Cipher.getInstance("AES/CBC/PKCS5Padding");
aesCBC.init(Cipher.ENCRYPT_MODE, key, iv);
byte[] decryptedData = aesCBC.doFinal(cipherText.getBytes("UTF-8"));
// String plainText = "Hello, World! This is a Java/Javascript AES test.";
// SecretKey key = new SecretKeySpec(
// Base64.decodeBase64("u/Gu5posvwDsXUnV5Zaq4g=="), "AES");
// AlgorithmParameterSpec iv = new IvParameterSpec(
// Base64.decodeBase64("5D9r9ZVzEYYgha93/aUK2w=="));
// Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
// cipher.init(Cipher.ENCRYPT_MODE, key, iv);
// System.out.println(Base64.encodeBase64String(cipher.doFinal(
// plainText.getBytes("UTF-8"))));
// String decryptedText = new String(decryptedData, "UTF-8");
System.out.println(Base64.encodeToString(decryptedData, Base64.NO_WRAP));
// enctest(decryptedText);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (InvalidKeyException e) {
e.printStackTrace();
} catch (InvalidAlgorithmParameterException e) {
e.printStackTrace();
} catch (NoSuchPaddingException e) {
e.printStackTrace();
} catch (BadPaddingException e) {
e.printStackTrace();
} catch (IllegalBlockSizeException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
但没有给出相同的结果。
But none gives the same results.
在iOS中他们正在使用 https： //github.com/etienne-martin/CryptoJS.swift
in iOS they are using https://github.com/etienne-martin/CryptoJS.swift
我应该怎样做才能使两个加密字符串匹配。
What should I do that both of our encrypted strings match.
推荐答案
实际 cipherText （不要混淆字符串与格式化相同的变量名称并以Salted__开头，可能是加密参数。两个不同的功能以不同的格式创建不同的输出。它们不能产生相同的输出。
The actual cipherText (not to be confused the character string with the same variable name) is formatted and starts with "Salted__" and presumably encryption parameters. The two different functions create different outputs with different formats. They can not produce the same output.
注1，混淆 cipherText ：
// String cipherText = "{\"device_type\":\"iOS\",\"email\" : \"jhon@gmail.com\",\"device_id\" : \"14105DA4-CEE5-431E-96A2-2331CDA7F062\",\"password\" : \"123456\",\"device_token\" : \"B44777563552882EC3139A0317E401B55D6FC699D0AC3D279F392927CAF9B566\"}";
// String cipherText = "U2FsdGVkX1+tsmZvCEFa/iGeSA0K7gvgs9KXeZKwbCDNCs2zPo+BXjvKYLrJutMK+hxTwl/hyaQLOaD7LLIRo2I5fyeRMPnroo6k8N9uwKk=";
注2：
Base64对人类无用，它专为计算机而设计，十六进制用于人和计算机，具有直接位到字节的对应关系。
Note 2:
Base64 is so un-useful for humans, it is designed for computers, hex is for humans and computers with a direct bits to bytes correspondence.
