react-native-fast-rsa

Android iOS

Getting started

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

JSI

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

import RSA from "react-native-fast-rsa";

RSA.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

export interface PCKS12KeyPair {
  publicKey: string;
  privateKey: string;
  certificate: string;
}
export interface KeyPair {
  publicKey: string;
  privateKey: string;
}

export enum Hash {
  MD5 = 0,
  SHA1 = 1,
  SHA224 = 2,
  SHA256 = 3,
  SHA384 = 4,
  SHA512 = 5,
}

export enum PEMCipher {
  DES = 0,
  D3DES = 1,
  AES128 = 2,
  AES192 = 3,
  AES256 = 4,
}

export enum SaltLength {
  AUTO = 0,
  EQUALS_HASH = 1,
}

Native Code

the native library is made in Golang for faster performance
