SSL Pinning

Last updated May 19, 2025, generated by Sumble

What is SSL Pinning?

SSL pinning is a security technique used to associate a host (website, API endpoint, etc.) with its expected X.509 certificate or public key. During development, the application developer pre-approves a certificate or public key, which is then embedded (pinned) within the app. At runtime, the application compares the server's certificate against the pinned certificate. If they don't match, the application should refuse to connect, preventing man-in-the-middle (MITM) attacks, even if the attacker has a valid certificate signed by a trusted Certificate Authority.
