How to Secure Mobile App Sessions, SSL Certificate Hardening

Learn 3 Easy Steps to secure mobile app sessions in Android and iOS Apps using SSL Certificate Hardening.

Why SSL Certificate Hardening is needed to protect Android and iOS Apps

In order to prevent certificate modification and MiTM attacks, certificates are generally signed. Most certificates are hashed using a hashing algorithm to produce a cryptographic hash, which is then encrypted using the CA’s private key. Generally speaking, the security of a certificate is determined by 2 things:

1. the encryption strength of the private key that was used to sign the certificate and
2. the strength of the hashing function used in the signature.

Until a few years ago, most certificates relied on the SHA1 hashing function, which is now obsolete and considered insecure. Most security professionals and reputed security organizations now recommend SHA-2, which has a significantly stronger key strength.

Appdome’s Certificate Signature Hardening protects all your application connections and enforces strong encryption and hashing methods such as RSA, ECC, and SHA-256 on each certificate signature.

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 and hashing methods with the following options:

• 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)

This Knowledge Base article provides step-by-step instructions for using Appdome to enforce Certificate Signature Hardening to increase the strength of digital certificates used in Android and iOS apps.
