React native rsa crypto lib

THIS IS A PORT OF https://www.npmjs.com/package/react-native-rsa-native FOR NODEJS

The use case

Initially this was created for encrypted messaging

Client would generate RSA key pairs and store private key locally and share the public key.

How to use

``
npm install react-native-rsa
`
Generate RSA keys
`
var RSAKey = require('react-native-rsa');
const bits = 1024;
const exponent = '10001'; // must be a string. This is hex string. decimal = 65537
var rsa = new RSAKey();
rsa.generate(bits, exponent);
var publicKey = rsa.getPublicString(); // return json encoded string
var privateKey = rsa.getPrivateString(); // return json encoded string
`

Encrypt

`
var rsa = new RSAKey();
rsa.setPublicString(publicKey);
var originText = 'sample String Value';
var encrypted = rsa.encrypt(originText);
`

Decrypt
`
rsa.setPrivateString(privateKey);
var decrypted = rsa.decrypt(encrypted); // decrypted == originText
``

Tested works with ursa in nodejs (with ursa padding set to PKCS1).
