Usage

Encrypt methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.encryptOAEP(message, label, RSAHash.sha512, publicKey)
var result = await RSA.encryptPKCS1v15(message, publicKey)

// Bytes methods at this moment only are available for Android and iOS
var result = await RSA.encryptOAEPBytes(messageBytes, label, RSAHash.sha512, publicKey)
var result = await RSA.encryptPKCS1v15Bytes(messageBytes, publicKey)

Decrypt methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.decryptOAEP(message, label, RSAHash.sha512, privateKey)
var result = await RSA.decryptPKCS1v15(message, privateKey)

// Bytes methods at this moment only are available for Android and iOS
var result = await RSA.decryptOAEPBytes(messageBytes, label, RSAHash.sha512, privateKey)
var result = await RSA.decryptPKCS1v15Bytes(messageBytes, privateKey)

Sign methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.signPSS(message, RSAHash.sha512, RSASaltLength.auto, privateKey)
var result = await RSA.signPKCS1v15(message, RSAHash.sha512, privateKey)

// Bytes methods at this moment only are available for Android and iOS
var result = await RSA.signPSSBytes(messageBytes, RSAHash.sha512, RSASaltLength.auto, privateKey)
var result = await RSA.signPKCS1v15Bytes(messageBytes, RSAHash.sha512, privateKey)

Verify methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.verifyPSS(signature, message, RSAHash.sha512, RSASaltLength.auto, publicKey)
var result = await RSA.verifyPKCS1v15(signature, message, RSAHash.sha512, publicKey)

// Bytes methods at this moment only are available for Android and iOS
var result = await RSA.verifyPSSBytes(signatureBytes, messageBytes, RSAHash.sha512, RSASaltLength.auto, publicKey)
var result = await RSA.verifyPKCS1v15Bytes(signatureBytes, messageBytes, RSAHash.sha512, publicKey)

Generate Methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.generate(2048)

Convert Methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.convertJWKToPrivateKey(data, keyId)
var result = await RSA.convertJWKToPublicKey(data, keyId)

var result = await RSA.convertKeyPairToPKCS12(privateKey, certificate, password)
var result = await RSA.convertPKCS12ToKeyPair(pkcs12, password)

var result = await RSA.convertPrivateKeyToPKCS8(privateKey)
var result = await RSA.convertPrivateKeyToPKCS1(privateKey)
var result = await RSA.convertPrivateKeyToJWK(privateKey)

var result = await RSA.convertPrivateKeyToPublicKey(privateKey)

var result = await RSA.convertPublicKeyToPKIX(publicKey)
var result = await RSA.convertPublicKeyToPKCS1(publicKey)
var result = await RSA.convertPublicKeyToJWK(publicKey)

var result = await RSA.encryptPrivateKey(privateKey, password, RSAPEMCipher.aes256)
var result = await RSA.decryptPrivateKey(privateKeyEncrypted, password)

Util Methods

import 'package:fast_rsa/rsa.dart';

var result = await RSA.hash(message, RSAHash.sha512)
var result = await RSA.base64(message)

Setup

Android

ProGuard

Add this lines to android/app/proguard-rules.pro for proguard support

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

iOS

no additional setup required

Web

add to you pubspec.yaml

assets:
  - packages/fast_rsa/web/assets/wasm_exec.js
  - packages/fast_rsa/web/assets/rsa.wasm

ref: https://github.com/jerson/flutter-rsa/blob/master/example/pubspec.yaml

and in you web/index.html

<script
  src="assets/packages/fast_rsa/web/assets/wasm_exec.js"
  type="application/javascript"
></script>

ref: https://github.com/jerson/flutter-rsa/blob/master/example/web/index.html

Linux

add to you linux/app_configuration.mk

EXTRA_LDFLAGS=-lrsa

ref: https://github.com/jerson/flutter-rsa/blob/master/example/linux/app_configuration.mk

MacOS

no additional setup required

Hover

just update your plugins

hover plugins get

Example

Inside example folder

cd example && flutter run

Native Code

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