Specifies SSL Pinning Pin Set values to validate HTTPS connection from devices to the server.


Generators: Android, Apple
Level: Front end


The SSL Pinning Pin Set defines the server's public key hash (pin sha-256). The Android generator allows defining a single key hash, while the Apple generator requires at least 2 key hashes, separated by a comma (,). In both cases, having more than one hash configured is recommended.

If this property has a value, a Certificate pinning is performed by the device when it is connected to the server set in the Services URL property.

Certificate pinning is done by providing a set of certificates by hash of the public key (SubjectPublicKeyInfo of the X.509 certificate). A certificate chain is then valid only if the certificate chain contains at least one of the pinned public keys.
