### Alipay.sign(object, privateKey)

If you want to do client side signature instead of server side (not recommend), you can use this.

- `privateKey` {String} Private key in `PKCS#1` or `PKCS#8` format.

Note: 
`PKCS#1` private key should have wrapped with `-----BEGIN RSA PRIVATE KEY-----` and `-----END RSA PRIVATE KEY-----`
`PKCS#8` private key should have wrapped with `-----BEGIN PRIVATE KEY-----` and `-----END PRIVATE KEY-----`

Returns The query string with signature. See [Process of signature](https://docs.open.alipay.com/291/106118) for detail.

Example code:

```javascript
import Alipay from '@0x5e/react-native-alipay';

// 签名
let params = {
  app_id: 2183,
  biz_content: '{"scopes":["auth_base"],"state":"init"}',
  method: 'alipay.user.info.auth',
  timestamp: '2017-10-13 00:00:00',
  version: '1.0',
};
let privateKey = '-----BEGIN RSA PRIVATE KEY-----\n' + ... + '\n-----END RSA PRIVATE KEY-----';
let signedQuery = Alipay.sign(params, privateKey);
console.info(signedQuery); // app_id=2183&biz_content=%7B%22scopes%22%3A%5B%22auth_base%22%5D%2C%22state%22%3A%22init%22%7D&method=alipay.user.info.auth&sign_type=RSA&timestamp=2017-10-13%2000%3A00%3A00&version=1.0&sign=xxxx
