Usage

Generate methods

import 'package:openpgp/openpgp.dart';

void main() async {
    var keyOptions = KeyOptions()..rsaBits = 1024;
    var keyPair = await OpenPGP.generate(
            options: Options()
              ..name = 'test'
              ..email = '[email protected]'
              ..passphrase = passphrase
              ..keyOptions = keyOptions);
}

Encrypt methods

import 'package:fast_rsa/rsa.dart';

void main() async {

    var bytesSample = Uint8List.fromList('data'.codeUnits);
    
    var result = await OpenPGP.encrypt("text","[publicKey here]");
    var result = await OpenPGP.encryptSymmetric("text","[passphrase here]");
    var result = await OpenPGP.encryptBytes(bytesSample,"[publicKey here]");
    var result = await OpenPGP.encryptSymmetricBytes(bytesSample,"[passphrase here]");

}

Decrypt methods

import 'package:fast_rsa/rsa.dart';

void main() async {

    var bytesSample = Uint8List.fromList('data'.codeUnits);
    
    var result = await OpenPGP.decrypt("text encrypted","[privateKey here]","[passphrase here]");
    var result = await OpenPGP.decryptSymmetric("text encrypted","[passphrase here]");
    var result = await OpenPGP.decryptBytes(bytesSample,"[privateKey here]","[passphrase here]");
    var result = await OpenPGP.decryptSymmetricBytes(bytesSample,"[passphrase here]");

}

Sign methods

import 'package:fast_rsa/rsa.dart';

void main() async {

    var bytesSample = Uint8List.fromList('data'.codeUnits);
    
    var result = await OpenPGP.sign("text","[publicKey here]","[privateKey here]","[passphrase here]");
    var result = await OpenPGP.signBytesToString(bytesSample,"[publicKey here]","[privateKey here]","[passphrase here]");

}

Verify methods

import 'package:fast_rsa/rsa.dart';

void main() async {

    var bytesSample = Uint8List.fromList('data'.codeUnits);
    
    var result = await OpenPGP.verify("text signed","text","[publicKey here]");
    var result = await OpenPGP.verifyBytes("text signed", bytesSample,"[publicKey here]");

}

Setup

Android

No additional setup required.

iOS

No additional setup required.

Web

Add to you pubspec.yaml.

assets:
    - packages/openpgp/web/assets/worker.js
    - packages/openpgp/web/assets/wasm_exec.js
    - packages/openpgp/web/assets/openpgp.wasm

ref: https://github.com/jerson/flutter-openpgp/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 OpenPGP.bindingEnabled = false in order to use channels instead of shared objects

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

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

Linux

No additional setup required.

Windows

No additional setup required.

Example

Inside example folder.

cd example && flutter run
