PHP加密函数
$privateKey = "1234567812345678";
$iv = "1234567812345678";
$data = "Test string";
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);
echo(base64_encode($encrypted));
Result: iz1qFlQJfs6Ycp+gcc2z4w==
当我尝试使用下面的函数在Java中解密此结果时,我只得到了ì�š@ÔBKxnfÈ~¯Ô'M,而我期望得到"Test string"。您有什么想法错在哪里吗?谢谢。
public static String decrypt() throws Exception{
try{
String Base64EncodedText = "iz1qFlQJfs6Ycp+gcc2z4w==";
String decodedText = com.sun.xml.internal.messaging.saaj.util.Base64.base64Decode(Base64EncodedText);
String key = "1234567812345678";
String iv = "1234567812345678";
javax.crypto.spec.SecretKeySpec keyspec = new javax.crypto.spec.SecretKeySpec(key.getBytes(), "AES");
javax.crypto.spec.IvParameterSpec ivspec = new javax.crypto.spec.IvParameterSpec(iv.getBytes());
javax.crypto.Cipher cipher = javax.crypto.Cipher.getInstance("AES/CBC/NoPadding");
cipher.init(javax.crypto.Cipher.DECRYPT_MODE, keyspec, ivspec);
byte[] decrypted = cipher.doFinal(decodedText.getBytes());
String str = new String(decrypted);
return str;
}catch(Exception e){
return null;
}
}
