Fast RSA

Library for use RSA

Usage

import 'package:fast_rsa/key_pair.dart';
import 'package:fast_rsa/rsa.dart';


const passphrase = '123456789';
const pkcs12 = '''MIIQSQIBAzCCEA8GCSqGSIb3DQEHAaCCEAAEgg/8MIIP+DCCBi8GCSqGSIb3DQEH

var encrypted = await RSA.encryptOAEP("text", "", RSAHash.sha256, pkcs12, passphrase);

var decrypted = await RSA.decryptOAEP("text encrypted", "", RSAHash.sha256, pkcs12, passphrase );

var encrypted = await RSA.encryptPKCS1v15("text", pkcs12, passphrase);

var decrypted = await RSA.decryptPKCS1v15("text encrypted", pkcs12, passphrase);

var signed = await RSA.signPSS("text", RSAHash.sha256, pkcs12, passphrase);

var verified = await RSA.verifyPSS("signed text", "text", RSAHash.sha256, pkcs12, passphrase);

var signed = await RSA.signPKCS1v15("text", RSAHash.sha256, pkcs12, passphrase);

var verified = await RSA.verifyPKCS1v15("signed text", "text", RSAHash.sha256, pkcs12, passphrase);

var keyPair = await RSA.generate(2048);

var hash = await RSA.hash("text here", RSAHash.sha512);
var base64 = await RSA.base64("text here");

ProGuard

Add this lines to proguard-rules.pro for proguard support

-keep class go.** { *; }
-keep class rsa.** { *; }

Sample

Inside example folder

cd example && flutter run

Native Code

the native library is made in Golang and build with gomobile for faster performance
