Certificate Signature Hardening

In order to prevent certificate modification by man in the middle attacks or otherwise, certificates are generally signed. Most certificates are hashed using a hashing algorithm to produce a fingerprint, which is then encrypted using the CA’s private key.

Appdome’s Certificate Signature Hardening protect all your application connections and enforce strong encryption methods such as RSA and ECC on each certificate signature.

This Knowledge Base article provides step-by-step instructions for using Appdome to enforce Certificate Signature Hardening on any Android and iOS mobile app

We hope you find it useful and enjoy using Appdome!

About Certificate Signature Hardening on Appdome

Appdome is a no code mobile integration platform as a service (IPaaS) that enables developers and non-developers to add a wide variety of features, SDKs, and APIs to Android and iOS apps instantly. Using a simple ‘click to add’ user interface, Appdome allows anyone to easily enforce Certificate Signature Hardening on any mobile app – instantly, no code or coding required.

There are no development or coding prerequisites to use Appdome. For example, there is no SDK, no libraries, or plug-ins to implement.

Appdome Certificate Signature Hardening service secures your app’s connections and verifying that aside from being secure HTTP connections, the certificates are signed using strong encryption methods:

  • Enforce Strong RSA Signature – enforces leaf and intermediary certificates received from the server to be signed with a Rivest-Shamir-Adleman (RSA) key with a length of at least 2048 bits
  • Enforce Strong ECC Signature – enforces leaf and intermediary certificates received from the server to be signed with an Elliptic-Curve Cryptography (ECC) key with a size of at least 256 bits
  • Enforce SHA256 Digest – enforces leaf and intermediary certificates received from the server to be signed using a Secure Hash Algorithm 2 (SHA-2) with a digest length of at least 256 bits (SHA-256 or greater)

Prerequisites for using Certificate Signature Hardening

How to Enforce Certificate Signature Hardening to Any Mobile App on Appdome 

Follow these step-by-step instructions to enforce Certificate Signature Hardening:

Upload a Mobile App to Your Account

Please follow these steps to add a mobile app to your Appdome account.
If you don’t have an Appdome account, click here to create an account.

From the “Build” tab, go to the Security menu.

  1. Click  Secure Communications to expend the bundle
  2. Click on the toggle to enable Trusted Session
  3. Expand Session Management.
  4. Toggle the Enforce Strong RSA Signature switch
    (optional) Fill out the custom message that is displayed in case of a security event.
  5. Toggle the Enforce Strong ECC Signature switch
    (optional) Fill out the custom message that is displayed in case of a security event.
  6. Toggle the Enforce SHA256 Digest switch
    (optional) Fill out the custom message that is displayed in case of a security event.
  7. (optional) Toggle the DEV-EventsTM switch, if your wish that your app will handle Appdome events.
  8. Click Build My App

The technology behind Build My App has two major elements – (1) a microservice architecture filled with 1000s of code sets needed for mobile integrations, and (2) an adaptive code generation engine that can recognize the development environment, frameworks and methods in each app and match the app to the relevant code-sets needed to add MicroVPN to the mobile app in seconds.

Congratulations! You now have a mobile app fully integrated with Certificate Signature Hardening

What to do After I Build My App?

After you successfully build an app, you need to sign the app in order to deploy it. You can also brand or customize an app on Appdome. Read this Knowledge Base article to learn what to do after you successfully build an app. It explains both optional steps and required steps.

That is it – Enjoy Appdome with Certificate Signature Hardening in your app!
