java部分代码：

String encBusiData = DataSecurityUtil.encrypt(jsonString.getBytes("UTF-8"), configABS.getValue("jks_key"));

    public static String encrypt(byte[] oriByte, String keyStr) throws Exception
    {
        try
        {
            byte[] sealTxt = null;
            SecretKey key = getKey(keyStr);
            Cipher cipher = null;
            try
            {
                cipher = Cipher.getInstance("DESede/ECB/PKCS5Padding");
                cipher.init(Cipher.ENCRYPT_MODE, key);
                sealTxt = cipher.doFinal(oriByte);
                BASE64Encoder encoder = new BASE64Encoder();
                String ret = encoder.encode(sealTxt);
                return ret;
            } catch (Exception e)
            {
                throw new Exception("E000035", e);
            }
            finally
            {
                cipher = null;
            }
        } catch (Exception ee)
        {
            throw new Exception(ee);
        }
    }

 

ruby 代码实现如下：

ruby需要使用gem 'keystores'

    def signature(bussiness_data)
      keystore = OpenSSL::JKS.new
      key_store_password = store_password
      keystore.load("#{Rails.root}/config/certs/credoo_stg.jks", key_store_password)
      private_key = keystore.get_key(store_alias, store_password)
      rkey = OpenSSL::PKey::RSA.new private_key
      sign = rkey.sign('SHA1', bussiness_data.force_encoding("utf-8"))
      signature = Base64.strict_encode64(sign)
      return convert_n(signature)
    end

    # java  base64 之后是76个字符换行 MIME：输出隐射到MIME友好格式。输出每行不超过76字符
    def convert_n(str)
      str_length = str.length
      if str_length > 76
        i = 1
        while (76 * i) < str_length
          str.insert(((76 * i) + i - 1), "\n")
          i = i + 1
        end
      end
      return str
    end

 

java代码中的验签代码如下：

    public static void verifyData(String data, String signValue) throws Exception
    {
        try
        {
            PublicKey key = getPublicKey();
            Signature sig = Signature.getInstance("SHA1WithRSA");
            sig.initVerify(key);
            sig.update(data.getBytes("utf-8"));
            BASE64Decoder decoder = new BASE64Decoder();
            byte[] signValueByte = decoder.decodeBuffer(signValue);
            if (!sig.verify(signValueByte))
            {
                throw new Exception("E000013");
            }
            System.out.println("验签OK！");
        } catch (Exception e)
        {
            throw new Exception("E000014", e);
        }
    }

ruby代码的实现如下：

    def rsa_verify(data, sign_value)
      public_key = OpenSSL::X509::Certificate.new(File.read("#{Rails.root}/config/certs/credoo_stg.cer")).public_key
      rsa = OpenSSL::PKey::RSA.new(public_key)
      rsa.verify("SHA1", Base64.decode64(sign_value), data)
    end
