Installation

first get source code.

$ git clone https://github.com/pesehr/secureKeyStore.git

• Android

  • goto Android folder and copy all java files to your android sorce code folder of your react native project. now ajust the codes with your project.

    new SecureKeyStoreModulePack()

    your code have must be like this:

    public class MainApplication extends Application implements ReactApplication {
        private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
        @Override

              return BuildConfig.DEBUG;
         }
        @Override
         protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new SecureKeyStoreModulePack()
                );
            }
        };
    }

  • in this module we use extrenal library named cryptoswift. you must install it before using the module. for installation follw this link: https://github.com/krzyzanowskim/CryptoSwift.
  • you must enable key chain sharing. follow this link: https://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppDistributionGuide/AddingCapabilities/AddingCapabilities.html
    • if you have problem with adding ios module. your can add ios native module by helping this link and my codes.
