Usage

Encrypt methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.encryptOAEP(message, label, Hash.HASH_SHA256, publicKey)
var result = await RSA.encryptPKCS1v15(message, publicKey)

var result = await RSA.encryptOAEPBytes(messageBytes, label, Hash.HASH_SHA256, publicKey)
var result = await RSA.encryptPKCS1v15Bytes(messageBytes, publicKey)

Decrypt methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.decryptOAEP(message, label, Hash.HASH_SHA256, privateKey)
var result = await RSA.decryptPKCS1v15(message, privateKey)

var result = await RSA.decryptOAEPBytes(messageBytes, label, Hash.HASH_SHA256, privateKey)
var result = await RSA.decryptPKCS1v15Bytes(messageBytes, privateKey)

Sign methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.signPSS(message, Hash.HASH_SHA256, SaltLength.SALTLENGTH_AUTO, privateKey)
var result = await RSA.signPKCS1v15(message, Hash.HASH_SHA256, privateKey)

var result = await RSA.signPSSBytes(messageBytes, Hash.HASH_SHA256, SaltLength.SALTLENGTH_AUTO, privateKey)
var result = await RSA.signPKCS1v15Bytes(messageBytes, Hash.HASH_SHA256, privateKey)

Verify methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.verifyPSS(signature, message, Hash.HASH_SHA256, SaltLength.SALTLENGTH_AUTO, publicKey)
var result = await RSA.verifyPKCS1v15(signature, message, Hash.HASH_SHA256, publicKey)

var result = await RSA.verifyPSSBytes(signatureBytes, messageBytes, Hash.HASH_SHA256, SaltLength.SALTLENGTH_AUTO, publicKey)
var result = await RSA.verifyPKCS1v15Bytes(signatureBytes, messageBytes, Hash.HASH_SHA256, publicKey)

Generate Methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.generate(2048)

Convert Methods

import 'package:fast_rsa/fast_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, PEMCipher.PEMCIPHER_AES256)
var result = await RSA.decryptPrivateKey(privateKeyEncrypted, password)

Util Methods

import 'package:fast_rsa/fast_rsa.dart';

var result = await RSA.hash(message, Hash.HASH_SHA256)
var result = await RSA.base64(message)

Setup

Android

No additional setup required.

iOS

No additional setup required.

Web

add to you pubspec.yaml

assets:
  - packages/fast_rsa/web/assets/worker.js
  - 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

MacOS

no additional setup required

Hover

Update your plugins.

hover plugins get

In you main_desktop.dart by now you need to add RSA.bindingEnabled = false in order to use channels instead of shared objects

import 'main.dart' as original_main;
import 'package:fast_rsa/fast_rsa.dart';

void main() {
  RSA.bindingEnabled = false;
  original_main.main();
}

Linux

No additional setup required.

Windows

No additional setup required.

Example

Inside example folder

cd example && flutter run

check our web demo: https://flutter-rsa.jerson.dev/
