我遵循本指南AES encryption on Java side - decryption on PHP side and selecting a single key,但接受的答案并没有真正起作用。我甚至在java中硬编码了KEY和IV值,这样我确信我在PHP中具有相同的值。
private static final byte[] keyValue =
new byte[] { 'T', 'h', 'e', 'B', 'e', 's', 't',
'S', 'e', 'c', 'r','e', 't', 'K', 'e', 'y' };
private static final byte[] ivValue =
new byte[] { '0', '1', '2', '3', '4', '5', '6',
'7', '8', '9', '0','1', '2', '3', '4', '5' };
JAVA(关键)代:
String ALGO = "AES/CBC/ZeroBytePadding";
Key key = new SecretKeySpec(keyValue, ALGO);
JAVA(iv)代:
IvParameterSpec ivSpec = new IvParameterSpec(ivValue);
然后我用它来加密/解密JAVA,如下所示:
//ENCRYPTION
String encrypted = encrypt("Hello World!",key,ivSpec);
//DECRYPTION
String decrypted = decrypt(encrypted,key,ivSpec);
public static String encrypt(String Data, Key key, IvParameterSpec ivSpec) throws Exception {
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.ENCRYPT_MODE, key, ivSpec);
byte[] encVal = c.doFinal(Data.getBytes());
String encryptedValue = Base64.encodeToString(encVal, Base64.NO_WRAP);
return encryptedValue;
}
public static String decrypt(String encryptedData, Key key, IvParameterSpec ivSpec) throws Exception {
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, key, ivSpec);
byte[] decordedValue = Base64.decode(encryptedData,Base64.NO_WRAP);
byte[] decValue = c.doFinal(decordedValue);
String decryptedValue = new String(decValue);
return decryptedValue;
}
现在,在PHP中,我通过POST获得加密值,并且我硬编码了KEY和IV值:
$encrypted = $_POST["encrypted"];
$key = "TheBestSecretKey";
$iv = "0123456789012345";
$decrypted = decryptMessage($encrypted,$key,$iv);
function decryptMessage($encrypted,$key,$iv)
{
$ivNum = (int)$iv;
$ivIn = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC), $ivNum);
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $encrypted, MCRYPT_MODE_CBC, $ivIn);
}
加密消息:TXCv3f + r + h71y / NzCk08Hw ==
(解密)变量的预期结果:“Hellow World!”
(解密)变量的当前结果: @ 6 I Ԗmݕ WMu
是否有其他解决方法可以达到我的预期效果。提前谢谢。
答案 0 :(得分:1)
您需要以十六进制提供密钥,iv,输入数据和加密数据,以便检查它们,加密适用于数据,而不是字符串。
键:546865426573745365637265744b6579
iv:30313233343536373839303132333435
文字:48656c6c6f7720576f726c6421
并且在CBC模式下使用零填充进行加密应该加密:
AE64AA4836D7251E03070C1647A4B531
但你没有,你得到
4D70AFDDFFABFA1EF5CBF3730A4D3C1F
所以看起来加密很糟糕。
