react-native-fast-openpgp

Getting started

$ npm install nodeua/react-native-fast-openpgp --save

Mostly automatic installation

`$ react-native link nodeua/react-native-fast-openpgp

on iOS is required to add this line to Podfile

pod 'FastOpenpgp', :path => '../node_modules/nodeua/react-native-fast-openpgp/ios/native'

and then Run pod install

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-fast-openpgp and add RNFastOpenpgp.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNFastOpenpgp.a to your project's Build Phases ➜ Link Binary With Libraries
4. In Podfile add

pod 'FastOpenpgp', :path => '../node_modules/nodeua/react-native-fast-openpgp/ios/native'

5. Run pod install
6. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import dev.jerson.RNFastOpenPGPPackage; to the imports at the top of the file
• Add new RNFastOpenPGPPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-fast-openpgp'
   project(':react-native-fast-openpgp').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-fast-openpgp/android')

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     implementation project(':react-native-fast-openpgp')

Usage

import OpenPGP from "react-native-fast-openpgp";

interface KeyOptions {
  cipher?: "aes128" | "aes192" | "aes256";
  compression?: "none" | "zlib" | "zip";
  hash?: "sha256" | "sha224" | "sha384" | "sha512";
  RSABits?: 2048 | 4096 | 1024;
  compressionLevel?: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9;
}
interface Options {
  comment?: string;
  email?: string;
  name?: string;
  passphrase?: string;
  keyOptions?: KeyOptions;
}
interface KeyPair {
  publicKey: string;
  privateKey: string;
}

const decrypted = await OpenPGP.decrypt(message: string, privateKey: string, passphrase: string): Promise<string>;
const encrypted = await OpenPGP.encrypt(message: string, publicKey: string): Promise<string>;
const signed = await OpenPGP.sign(message: string, publicKey: string, privateKey: string, passphrase: string): Promise<string>;
const verified = await OpenPGP.verify(signature: string, message: string, publicKey: string): Promise<boolean>;
const decryptedSymmetric = await OpenPGP.decryptSymmetric(message: string, passphrase: string, options?: KeyOptions): Promise<string>;
const encryptedSymmetric = await OpenPGP.encryptSymmetric(message: string, passphrase: string, options?: KeyOptions): Promise<string>;
const generated = await OpenPGP.generate(options: Options): Promise<KeyPair>;
