What does it mean to pin a certificate?
Certificate pinning restricts which certificates are considered valid for a particular website, limiting risk. Instead of allowing any trusted certificate to be used, operators “pin” the certificate authority (CA) issuer(s), public keys or even end-entity certificates of their choice.
Is certificate pinning recommended?
It is possible, though not recommended, to perform pinning with only the intermediate certificate as you place all your trust in the intermediate CA. Leaf Certificate: This represents the highest-level cert in a chain. The pinning of a leaf certificate virtually assures a certificate match.
What is the best description of certificate pinning?
Certificate pinning is a process in which a non-browser desktop/mobile application validates that the TLS certificates presented by the application’s backend TLS web servers match a known set of certificates pinned or hardcoded in the application.
What does Certificate pinning protect against?
Certificate pinning was originally developed to protect web and mobile apps from rogue certificate authorities. Pinning ensures that no network data is compromised even if a user is tricked into installing a malicious root certificate on their mobile device.
What is SSL pinning and how it works?
With this technique, you can pin SSL certificate host – list of trustful certificates to your application during development and further compare the server certificates against the list during runtime. As the app validates the server certificates yet again after SSL handshaking, it ensures an extra layer of protection.
What software uses OpenSSL?
