## Usage 

```js
import AesCrypto from 'react-native-aes-pack';

const plaintxt = 'test';
const secretKey = '0102030405060708';
const iv = '1112131415161718';

AesCrypto.encrypt(plaintxt,secretKey,iv).then(cipher=>{
    console.log(cipher);// return a string type cipher
    this.setState({ cipher });
}).catch(err=>{
    console.log(err);
});

AesCrypto.decrypt(this.state.cipher,secretKey,iv).then(plaintxt=>{
    console.log(plaintxt);// return a string type plaintxt
}).catch(err=>{
    console.log(err);
});
