PashaArkus / simple_rsa2

A fork of the original package for flutter simple_rsa.

Notice

This package is a fork of the original simple_rsa package, all the credit is to their original authors. We created this package just to have an updated version of this awesome library, our plans are to keep as updated as possible :).

Simple RSA Encryption

Flutter plugin to encrypt, decrypt (RSA/ECB/PCSK1), verify and sign string with a public and a private key

Support for ANDROID and iOS(thanks to adlanarifzr)

Installation

To use the plugin, add simple_rsa2 as a dependency in your pubspec.yaml file.

Usage

First, initialize private and public key. Preferably in BASE64 format.

final publicKey = '...';
final privateKey = '...';

After that, you can encrypt or decyrpt text

let plainText = 'something';
final encryptedText = await encryptString(plainText, utf8.decode(base64.decode(publicKey)));
final decryptedText = await decryptString(encryptedText, utf8.decode(base64.decode(privateKey)));

// Test
print(plainText == decryptedText ? 'true' : 'false');

Or you might want to sign and verify text

let plainText = 'something';
final signedText = await signString(plainText, utf8.decode(base64.decode(privateKey)));
final verified = await verifyString(plainText, signedText, utf8.decode(base64.decode(publicKey)));

// Test
print(verified ? 'true' : 'false');
