About

The SSL pinning is a technique mitigating man-in-the-middle attacks against the secure HTTP communication, but has a drawback, the certificate's expiration date. This resolve this problem, implementing dynamic SSL pinning, providing easy to use fingerprint validation on the TLS handshake. The remote server must be the responsible to update the certificate(s).

Installation

npm i -s @yoonit/nativescript-handshake  

Special thanks and credits...

The current version of the library depends on [Wultra SSL Pinning] ([Android]((https://github.com/wultra/ssl-pinning-android) and iOS)).

Usage

function updateFingerprint() {
  this.$yoo.handshake.updateFingerprints(
    "YOUR PUBLIC KEY",
    "YOUR SERVICE URL",
    (result) => {
      switch (result) {
        case HandshakeResult.OK:
          // - Everything is OK;
          // - No Action is required;
          return;

        case HandshakeResult.STORE_IS_EMPTY:
          // - The update request succeeded;
          // - Result is still an empty list of certificates;
          // - May loading & validating of remote data succeeded;
          // - All loaded certificates are already expired;"
          return;

        case HandshakeResult.NETWORK_ERROR:
          // - The update request failed on a network communication.
          return;

        case HandshakeResult.INVALID_DATA:
          // The update request returned the data which did not pass the signature validation.
          return;

        case HandshakeResult.INVALID_SIGNATURE:
          // The update request returned the data which did not pass the signature validation.
          return;

        case HandshakeResult.INVALID_URL_SERVICE:
          // The url service does not exist or is invalid.
          return;
      }
    }
  );
}
