react-native-fast-rsa


Getting started

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

JSI

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

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

RSA.useJSI = false;
`
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

`typescript

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
