Getting started

$ npm install react-native-ssl-pinning --save

Mostly automatic installation

If you are using React Native 0.60.+ the link should happen automatically. in iOS run pod install

$ react-native link react-native-ssl-pinning

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-ssl-pinning and add RNSslPinning.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNSslPinning.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

Add maven { url "https://jitpack.io" } to project level build.gradle like this:

allprojects {
    repositories {
    maven { url "https://jitpack.io" }
    }
}

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

• Add import com.toyberman.RNSslPinningPackage; to the imports at the top of the file
• Add new RNSslPinningPackage() to the list returned by the getPackages() method

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

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

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

     compile project(':react-native-ssl-pinning')
   

Usage

Create the certificates:

1. openssl s_client -showcerts -connect google.com:443 (replace google with your domain)

2. Copy the certificate (Usally the first one in the chain), and paste it using nano or other editor like so , nano mycert.pem

3. convert it to .cer with this command openssl x509 -in mycert.pem -outform der -out mycert.cer

iOS

• drag mycert.cer to Xcode project, mark your target and 'Copy items if needed'

Android

• Place your .cer files under src/main/assets/.

import {fetch, removeCookieByName} from 'react-native-ssl-pinning';

fetch(url, {
    method: "POST" ,
    timeoutInterval: communication_timeout, // milliseconds
    body: body,
    // your certificates array (needed only in android) ios will pick it automatically
    sslPinning: {
        certs: ["cert1","cert2"]
    },
    headers: {
        Accept: "application/json; charset=utf-8", "Access-Control-Allow-Origin": "*", "e_platform": "mobile",
    }
}).then(response => {
    console.log(`response received ${response}`)
})
.catch(err => {
    console.log(`error: ${err}`)
})

removeCookieByName('cookieName')
    .then(res =>{
            console.log('removeCookieByName');
    })

getCookies('domain')
    .then(cookies => {
        // do what you need with your cookies
    })

Multipart request (FormData)

let formData = new FormData()

#You could add a key/value pair to this using #FormData.append:

formData.append('username', 'Chris');

# Adding a file to the request
formData.append('file', {
        name: encodeURIComponent(response.fileName),
        fileName: encodeURIComponent(response.fileName),
        type: this._extractFileType(response.fileName),
        uri: response.uri,
        data: response.data // needed for ios in base64
})

fetch(url, {
    method: "POST" ,
    timeoutInterval: communication_timeout, // milliseconds
    body: {
                formData: request,
    },
    sslPinning: {
        certs: ["cert1","cert2"]
    },
    headers: {
                'content-type': 'multipart/form-data; charset=UTF-8',
                accept: 'application/json, text/plain, /',
        }
})
