Which rsa library recommended for "react native" platform?

Question

Which rsa library recommended for "react native" platform with android support?

Thank you

EDIT:

I tried react-native-rsa:

var encrypted = '';
try {
  var RSAKey = require('react-native-rsa');
  const bits = 1024;
  const exponent = '10001';
  var rsa = new RSAKey();
  rsa.generate(bits, exponent);
  var publicKey = rsa.getPublicString(); 
  var privateKey = rsa.getPrivateString(); 
} catch (error) {
  console.log(1);
  console.log(error);
}

try {

  rsa = new RSAKey();
  rsa.setPrivateString(privateKey);
  var originText = 'Test 123 Test 321';
  encrypted = rsa.encrypt(originText);

} catch (error) {
  console.log(2);
  console.log(error);
}

try {
  rsa = new RSAKey();
  rsa.setPublicString(publicKey);
  var decrypted = rsa.decrypt(encrypted);
  console.log(decrypted);

} catch (error) {
  console.log(3);
  console.log(error);
}

But I got this error:

Try react-native-rsa, it's simple to use and will support android platform.

First install library using Npm:

npm install react-native-rsa

Generate RSA keys:

var RSAKey = require('react-native-rsa');
const bits = 1024;
const exponent = '10001'; // must be a string
var rsa = new RSAKey();
var r = rsa.generate(bits, exponent);
var publicKey = rsa.RSAGetPublicString(); // return json encoded string
var privateKey = rsa.RSAGetPrivateString(); // return json encoded string

Encript:

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

Decript:

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