Usage

Generate methods

import 'package:openpgp/openpgp.dart';

var keyPair = await OpenPGP.generate(
      options: Options(
        name: 'test',
        comment: 'test',
        email: 'test@test.com',
        passphrase: "123456",
        keyOptions: KeyOptions(
            rsaBits: 2048,
            cipher: Cypher.aes128,
            compression: Compression.none,
            hash: Hash.sha256,
            compressionLevel: 0,
        ),
      ),
);

Encrypt methods

import 'package:fast_rsa/rsa.dart';

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';

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';

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';

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

ProGuard

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

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

iOS

no additional setup required

Web

add to you pubspec.yaml

assets:
  - 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

and in you web/index.html

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

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

Linux (need to upgrade to new linux flutter template, use older version)

add to you linux/app_configuration.mk

EXTRA_LDFLAGS=-lopenpgp

ref: https://github.com/jerson/flutter-openpgp/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
