我試圖加密java中的數據並在ruby中解密數據。AES/CBC/PKCS5Padding在java中解密ruby加密
我發現幾乎相同的要求,但我的情況有點不同。
我的代碼... 加密在java中
import java.util.HashMap;
import java.util.Map;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import net.sf.json.JSONObject;
import org.apache.commons.codec.binary.Hex;
class Crypt {
public static void main(String[] args) throws Exception {
Map<String, String> node = new HashMap<String, String>();
node.put("timestamp", "1377499097199");
JSONObject jsonObject = JSONObject.fromObject(node);
String json = jsonObject.toString();
System.out.println(json);
//key
String skeyString = "97128424897797a166913557a6f4cc8e";
byte[] skey = Hex.decodeHex(skeyString.toCharArray());
System.out.println("key : " + skeyString);
//iv
String ivString = "84e8c3ea8859a0e293941d1cb00a39c3";
byte[] iv = Hex.decodeHex(ivString.toCharArray());
System.out.println("iv : " + ivString);
//encrypt
SecretKeySpec skeySpec1 = new SecretKeySpec(skey, "AES");
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, skeySpec1, new IvParameterSpec(iv));
byte[] encrypted = cipher.doFinal(json.getBytes());
String encryptedString = Hex.encodeHexString(encrypted);
System.out.println("=============>");
System.out.println("encrypted string: " + encryptedString);
}
}
結果是
{"timestamp":"1377499097199"}
key : 97128424897797a166913557a6f4cc8e
iv : 84e8c3ea8859a0e293941d1cb00a39c3
=============>
encrypted string: 395f6c0e8ad27f57c4a5a8975aa633e5b26f288d37ce18c6971779951f3b3527
,我希望解密(加密的字符串)在Ruby中
Ruby代碼是...(有誤差)
require 'openssl'
key = "97128424897797a166913557a6f4cc8e"
iv = "84e8c3ea8859a0e293941d1cb00a39c3"
encrypted_string = "395f6c0e8ad27f57c4a5a8975aa633e5b26f288d37ce18c6971779951f3b3527"
de_cipher = OpenSSL::Cipher::Cipher.new("AES-256-CBC")
de_cipher.decrypt
de_cipher.key = key
de_cipher.iv = iv
de_cipher.update(encrypted_string) << de_cipher.final
我有望獲得
{"timestamp":"1377499097199"}
但它返回錯誤
`final': bad decrypt (OpenSSL::Cipher::CipherError)
我認爲問題是cipher.padding和鍵/ iv的類型。 但我不知道如何完成ruby代碼。
請讓我知道如何填寫此代碼。
謝謝。
請你幫我出加密的紅寶石也或者只是告訴寶石名稱 – VKatz
