React-Native ssl pinning & public key pinning using OkHttp 3 in Android, and AFNetworking on iOS.
- for RN 0.60.0 or later use
react-native-ssl-pinning@latest
$ npm install react-native-ssl-pinning --save
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
- In XCode, in the project navigator, right click
Libraries
➜Add Files to [your project's name]
- Go to
node_modules
➜react-native-ssl-pinning
and addRNSslPinning.xcodeproj
- In XCode, in the project navigator, select your project. Add
libRNSslPinning.a
to your project'sBuild Phases
➜Link Binary With Libraries
- Run your project (
Cmd+R
)<
Add maven { url "https://jitpack.io" } to project level build.gradle like this:
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
- 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 thegetPackages()
method
- 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')
- Insert the following lines inside the dependencies block in
android/app/build.gradle
:compile project(':react-native-ssl-pinning')
-
openssl s_client -showcerts -servername google.com -connect google.com:443 </dev/null
-
Copy the certificate (Usally the first one in the chain), and paste it using nano or other editor like so , nano mycert.pem
-
convert it to .cer with this command openssl x509 -in mycert.pem -outform der -out mycert.cer
For more ways to obtain the server certificate please refer:
https://stackoverflow.com/questions/7885785/using-openssl-to-get-the-certificate-from-a-server
- drag mycert.cer to Xcode project, mark your target and 'Copy items if needed'
- (skip this if you are using certificate pinning) no extra step needed for public key pinning, AFNetworking will extract the public key from the certificate.
-
Only if using certificate pinning : place your .cer files under src/main/assets/
-
For public key pinning the public key should be extracted by the following options : (replace google with your domain)
openssl s_client -servername google.com -connect google.com:443 | openssl x509 -pubkey -noout | openssl rsa -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64
- Turn on pinning with a broken configuration and read the expected configuration when the connection fails.
fetch("https://publicobject.com", { method: "GET" , pkPinning: true, sslPinning: { certs: ["sha256/AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA="] } })
- Now look at your logcat , As expected, this fails with a certificate pinning exception:
javax.net.ssl.SSLPeerUnverifiedException: Certificate pinning failure! Peer certificate chain: sha256/afwiKY3RxoMmLkuRW1l7QsPZTJPwDS2pdDROQjXw8ig=: CN=publicobject.com, OU=PositiveSSL sha256/klO23nT2ehFDXCfx3eHTDRESMz3asj1muO+4aIdjiuY=: CN=COMODO RSA Secure Server CA sha256/grX4Ta9HpZx6tSHkmCrvpApTQGo67CYDnvprLg5yRME=: CN=COMODO RSA Certification Authority sha256/lCppFqbkrlJ3EcVFAkeip0+44VaoJUymbnOaEUk7tEU=: CN=AddTrust External CA Root Pinned certificates for publicobject.com: sha256/AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA= at okhttp3.CertificatePinner.check(CertificatePinner.java) at okhttp3.Connection.upgradeToTls(Connection.java) at okhttp3.Connection.connect(Connection.java) at okhttp3.Connection.connectAndSetOwner(Connection.java)
- Follow up by pasting the public key hashes from the exception into the certificate pinner's configuration
- Now look at your logcat , As expected, this fails with a certificate pinning exception:

don't add 'content-type': 'multipart/form-data; charset=UTF-8',
Setting the Content-Type header manually means it's missing the boundary parameter. Remove that header and allow fetch to generate the full content type.
