A native implementation of RSA key generation and encryption/decryption.
A native implementation of RSA key generation and encryption/decryption, sign/verify. Keychain implementation Implementation is in PKCS1
iOS 10+ android 4.1+ (API 16)
Features: Generation, Encryption, Decryption, Sign, Verify, Keychain support
$ yarn add react-native-rsa-native
or:
$ npm install react-native-rsa-native --save
$ react-native link react-native-rsa-native
In your React Native Xcode project, right click on your project and go 'Add Files to ...', then navigate to /node_modules/react-native-rsa-native/ios and select the RNRSA.xcodeproj file. Then in the build settings for your target under 'Link Binary With Libraries', add libRNRSA.a.
import {RSA, RSAKeychain} from 'react-native-rsa-native';
RSA.generateKeys(4096) // set key size
.then(keys => {
console.log('4096 private:', keys.private) // the private key
console.log('4096 public:', keys.public) // the public key
})
RSA.generate()
.then(keys => {
console.log(keys.private) // the private key
console.log(keys.public) // the public key
RSA.encrypt('1234', keys.public)
.then(encodedMessage => {
RSA.decrypt(encodedMessage, keys.private)
.then(message => {
console.log(message);
})
})
RSA.sign(secret, keys.private)
.then(signature => {
console.log(signature);
RSA.verify(signature, secret, keys.public)
.then(valid => {
console.log(valid);
})
})
})
// Example utilizing the keychain for private key secure storage
let keyTag = 'com.domain.mykey';
let secret = "secret message";
RSAKeychain.generate(keyTag)
.then(keys => {
console.log(keys.public);
console.log(secret);
return RSAKeychain.encrypt(secret, keyTag)
.then(encodedMessage => {
console.log(encodedMessage);
RSAKeychain.decrypt(encodedMessage, keyTag)
.then(message => {
console.log(message);
})
})
})
.then(() => {
return RSAKeychain.sign(secret, keyTag)
.then(signature => {
console.log('signature', signature);
RSAKeychain.verify(signature, secret, keyTag)
.then(valid => {
console.log('verified', valid);
})
})
})
.then(() => {
RSAKeychain.deletePrivateKey(keyTag)
.then( success => {
console.log('delete success', success)
})
});
