The Platform Security Architecture (PSA) APIs define the foundations from which security services are built, allowing devices to be secure by design. Three sets of APIs have been defined, so far, and include Crypto, Secure Storage and Attestation.

These documents explain the rationale behind each API, how they are architected and how to use them in practice. PSA API users may benefit from reviewing these documents first, before diving into the reference code available on GitHub.
