Certificate pinning

Meaning in software engineering, with examples

nounAdvanced term

In software engineering, certificate pinning means: Restricting a client's accepted server certificates or public keys beyond the usual certificate trust checks.

In Turkish: sertifika sabitleme

How it is used

Used in some clients to narrow trust. Certificate or key rotation must be planned so legitimate servers remain reachable.

Example sentences

  1. Our certificate pinning rejected the proxy certificate even though its issuer was trusted locally.

    The certificate passed broader trust checks but did not match the client's additional restriction.

  2. We updated certificate pinning before rotating the server's public key.

    A legitimate key change can break clients whose allowed pins are outdated.

Common collocations

  • implement certificate pinning
  • certificate pinning failure
  • digital certificateAn electronic document that links a public key to an identity, such as a website or a person, and is signed by a trusted certificate authority.
  • TLSTransport Layer Security: the standard protocol that encrypts data travelling between two systems, such as a browser and a website, and checks the server's identity.
