TLS/SSL 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 protects all your application connections and enforces 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 by verifying that aside from being secure HTTP connections, the certificates are also 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)
