データは PHP で OpenSSL を使用して暗号化されています。Java を復号化したいのですが、Java でエラーが発生します
PHP での暗号化のためのコード-
public function getEncryptedString($cardNumber,$key_id){
$encryptedCardNumber = '';
$key_name = "key_{$key_id}";
$pub_key_path =$key_name.".public";
$fp=fopen ($pub_key_path,"r"); //Open the public key (key_8.public)
$pub_key = fread($fp,8192); //Read public key key (key_8.public) into
fclose($fp);
openssl_public_encrypt($cardNumber,$encryptedCardNumber,$pub_key);
if($key_id > 4) return rawurlencode(base64_encode($encryptedCardNumber));
else return addslashes($encryptedCardNumber);
}
JAVA での復号化のためのコード-
public static String getDecryptedValue(int keyId,String encryptedCCNumber ,String passPhrase){
String result="";
String privateKeyFileName="key_8.private";
String privateKeyLocation= PropertiesUtil.getProperty("PUBLIC_PRIVATE_KEY_LOCATION");
String privateKeyFileNameLocation=privateKeyLocation+privateKeyFileName;
String decryptedValue= getDecryptedMessage(privateKeyFileNameLocation,encryptedCCNumber,passPhrase);
return result;
}
public static String getDecryptedMessage(String privateKeyFileNameLocation, String encryptedCCNumber,String passPhrase)
{
byte[] decodedBytesCCNumber= Base64.decodeBase64(encryptedCCNumber.getBytes());
byte[] decryptedMessage=null;
try {
Cipher cipher = Cipher.getInstance("RSA");
PrivateKey privateKey = getPrivateKey(privateKeyFileNameLocation,passPhrase);
cipher.init(Cipher.DECRYPT_MODE, privateKey);
decryptedMessage = cipher.doFinal(decodedBytesCCNumber);
} catch (Throwable t) {
t.printStackTrace();
}
System.out.println("new String(decryptedMessage)"+new String(decryptedMessage));
return new String(decryptedMessage);
}
private static PrivateKey getPrivateKey(String privateKeyFileNameLocation,String passPhrase) throws KeyStoreException, IOException, NoSuchAlgorithmException, CertificateException, UnrecoverableEntryException {
KeyStore ks = KeyStore.getInstance("PKCS12");
ks.load(new FileInputStream(privateKeyFileNameLocation), passPhrase.toCharArray());
String alias = (String) ks.aliases().nextElement();
KeyStore.PrivateKeyEntry keyEntry = (KeyStore.PrivateKeyEntry) ks.getEntry(alias, new KeyStore.PasswordProtection(passPhrase.toCharArray()));
return keyEntry.getPrivateKey();
}
Javaコードで以下のエラーが発生しています。
