How to Use Certificate Pinning in Enterprise Mobile Apps

Last updated December 31, 2023 by Appdome

Certificates are usually verified against intermediate CA certificates, which are then verified against root CA certificates. Root CA certificates are normally stored on a device’s trusted CA store. Certificate Pinning is the process in which an app stores specific certificates or public key hashes in the app itself, thereby foregoing the verification process as described above. Instead, the app verifies a server certificate or CA certificate it received directly against the stored certificate or public key hash. This knowledge base article details how to use certificate pinning in enterprise mobile apps.

To allow Apple’s Per-App VPN to handle the traffic, some Appdome features will be turned off automatically, or an error will be displayed

Even though Per-App VPN may tunnel an app’s entire network connectivity, you are still able to secure your app by using complementary Appdome features such as:

  1. Enforce Strong RSA Signature
  2. Enforce Strong ECC Signature
  3. Enforce SHA256 Digest
  4. Enforce Certificate Roles
  5. Validating Basic Constraints for CA certificates
  6. Static Client Pinning and Certificate Pinning
  7. Authentication using NTLM or: Basic authentication, Digest, Ngotiate or an HTML form.
