react-native-fast-openpgp

Getting started

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

JSI

If you want to use with JSI instead of NativeModules you need to set

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

OpenPGP.useJSI = true;

if you need to use generate methods it is a good idea to disable it, because for now JSI will block your UI but it is faster compared to NativeModules

Usage

Encrypt methods

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

const encrypted = await OpenPGP.encrypt(message: string, publicKey: string, signedEntity?: Entity, fileHints?: FileHints, options?: KeyOptions ): Promise<string>;
const outputFile = await OpenPGP.encryptFile(inputFile: string, outputFile: string, publicKey: string, signedEntity?: Entity, fileHints?: FileHints, options?: KeyOptions): Promise<number>;

const encryptedSymmetric = await OpenPGP.encryptSymmetric(message: string, passphrase: string, fileHints?: FileHints, options?: KeyOptions ): Promise<string>;
const outputFile = await OpenPGP.encryptSymmetricFile(inputFile: string, outputFile: string, passphrase: string, fileHints?: FileHints, options?: KeyOptions ): Promise<number> ;

Decrypt methods

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

const decrypted = await OpenPGP.decrypt(message: string, privateKey: string, passphrase: string, options?: KeyOptions ): Promise<string>;
const outputFile = await OpenPGP.decryptFile(inputFile: string, outputFile: string, privateKey: string, passphrase: string, options?: KeyOptions ): Promise<number>;

const decryptedSymmetric = await OpenPGP.decryptSymmetric(message: string, passphrase: string, options?: KeyOptions ): Promise<string>;
const outputFile = await OpenPGP.decryptSymmetricFile(inputFile: string, outputFile: string, passphrase: string, options?: KeyOptions ): Promise<number> ;

Sign and Verify methods

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

const signed = await OpenPGP.sign(message: string, privateKey: string, passphrase: string, options?: KeyOptions ): Promise<string>;
const signed = await OpenPGP.signFile(inputFile: string, privateKey: string, passphrase: string, options?: KeyOptions ): Promise<string>;

const verified = await OpenPGP.verify(signature: string, message: string, publicKey: string ): Promise<boolean>;
const verified = await OpenPGP.verifyFile(signature: string, inputFile: string,publicKey: string): Promise<boolean>;

Generate

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

const generated = await OpenPGP.generate(options: Options): Promise<KeyPair>;

Convert methods

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

const publicKey = await OpenPGP.convertPrivateKeyToPublicKey(privateKey: string): Promise<string>;

Metadata methods

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

const metadata1 = await OpenPGP.getPublicKeyMetadata(publicKey: string): Promise<PublicKeyMetadata>;
const metadata2 = await OpenPGP.getPrivateKeyMetadata(privateKey: string): Promise<PrivateKeyMetadata>;

Encrypt with multiple keys

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

const publicKeys = `-----BEGIN PGP PUBLIC KEY BLOCK-----
