.net 和 java RSA加密问题

[梦天城]

首先我是个c#小白，被拉去写c#demo，到现在类都没创建出来，用的一个别人的项目改的
那么问题来了，我先贴java解密的代码
解密时出现javax.crypto.BadPaddingException: Decryption error

//byte[] aesKeyByte ，getdata是string类型数据
BeanUtils.json2Bean(AesRsaUtil.decryptData((String)e.getData(), aesKeyByte, "UTF-8")

   public static String decryptData(String resEncryptData, byte[] aesKeyBytes, String charset) throws UnsupportedEncodingException {
        byte[] decodeBase64DataBytes = Base64.decodeBase64(resEncryptData.getBytes(charset));
        byte[] aesDecryptData = AESDecrypt(decodeBase64DataBytes, aesKeyBytes, "AES", "AES/ECB/PKCS5Padding", (String)null);
        return new String(aesDecryptData, charset);
    }

public static byte[] AESDecrypt(byte[] encryptedBytes, byte[] keyBytes, String keyAlgorithm, String cipherAlgorithm, String IV) {
        try {
            if(keyBytes.length % 8 == 0 && keyBytes.length >= 16 && keyBytes.length <= 32) {
                Cipher ee = Cipher.getInstance(cipherAlgorithm);
                SecretKeySpec secretKey = new SecretKeySpec(keyBytes, keyAlgorithm);
                if(IV != null && StringUtils.trimToNull(IV) != null) {
                    IvParameterSpec decryptedBytes = new IvParameterSpec(IV.getBytes());
                    ee.init(2, secretKey, decryptedBytes);
                } else {
                    ee.init(2, secretKey);
                }

                byte[] decryptedBytes1 = ee.doFinal(encryptedBytes);
                return decryptedBytes1;
            } else {
                return null;
            }
        } catch (Exception var8) {
            var8.printStackTrace();
            return null;
        }
    }

下面是.net加密的代码

 // ZITOPAY_RSA_PUBLICKEY公钥加密 ，后面
            string aesKey = Guid.NewGuid().ToString().Replace("-", "").Substring(0, 16);//16位随机数

         byte[] byteArray = Encoding.UTF8.GetBytes(aesKey);
           string signature = RSAEncrypt(ZITOPAY_RSA_PUBLICKEY, byteArray);


 public static string RSAEncrypt(string xmlPublicKey, byte[] EncryptString)
        {
           try
            {
                string publickey = "<RSAKeyValue><Modulus>MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxISByn8ytHt2XWZczV0qCV8yM+RSJwxh7YNfkzOh9LkED4xfWTFHl76kwopZqliQwO4c+8Y0B3yYNDSDxgiw0eBPCZ45yyeZ5WFl3a5JTi31OQU9FWv28DQxjXNyWw8xBoo8PHcdthosuzjLbYZvYgus/g0dSbDIp+EEXTOkUn99PKa7AGKuJpVxQmHDZPsWlO8V3cfGfyRu6+Iff6QLIhCVXc3PbK9WnvhCwVocoMIYQYefBjftCppskn80bGr1X4cBwFlgrDSepS7E9/GTUfSh1dScSk6q91oRdTiP5n4n6lk7lWn8bD5C/NDa5yOvskGU/qbx5XIF+kHyiKQ6NwIDAQAB</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>";
                byte[] CypherTextBArray;
                string Result;
                System.Security.Cryptography.RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(2048);
                rsa.FromXmlString(publickey);
                CypherTextBArray = rsa.Encrypt(EncryptString, false);
                Result = Convert.ToBase64String(CypherTextBArray);
                return Result;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

java的公钥，c#的是我自己拼出来的不知道对不对
	public static final String ZITOPAY_RSA_PUBLICKEY = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxISByn8ytHt2XWZczV0qCV8yM+RSJwxh7YNfkzOh9LkED4xfWTFHl76kwopZqliQwO4c+8Y0B3yYNDSDxgiw0eBPCZ45yyeZ5WFl3a5JTi31OQU9FWv28DQxjXNyWw8xBoo8PHcdthosuzjLbYZvYgus/g0dSbDIp+EEXTOkUn99PKa7AGKuJpVxQmHDZPsWlO8V3cfGfyRu6+Iff6QLIhCVXc3PbK9WnvhCwVocoMIYQYefBjftCppskn80bGr1X4cBwFlgrDSepS7E9/GTUfSh1dScSk6q91oRdTiP5n4n6lk7lWn8bD5C/NDa5yOvskGU/qbx5XIF+kHyiKQ6NwIDAQAB";

各位大神c#怎么写啊，小弟我真心不知道啊，哪儿有问题 c#公钥加密，java私钥解密

[哎呦呵-net]

感觉不对 我看java的加密算法是这个 RSA/ECB/PKCS1Padding 用你发的这个会出现解密失败

把C# 的加密解密代码封装成一个 COM 调用，然后 Java 调 COM 就 OK 啦。

现在是java服务端的是不能动的啊！ 我要跟服务端对接，AES/ECB/PKCS5Padding java那边的算法，c#我也不会，找了好多都不管

java是aes对称加密，你下面的net代码为啥是rsa非对称？

java采用的是两次加密，有一遍是非对称加密的
