TF PSA Crypto drivers

Introduction

This repository contains cryptographic drivers that implement the PSA Cryptoprocessor Driver Interface, for example, to be further integrated within Trusted-Firmware-M based platforms.

The PSA Cryptoprocessor Driver Interface is designed to interface with a PSA Crypto core component, such as the reference implementation available in TF-PSA-Crypto. For more details on the capabilities implemented through such interfaces please refer directly to their respective documentation. The PSA Crypto core component exposes PSA Crypto APIs, for example the PSA Cryptography API 1.1.

Repository structure

PSA Crypto drivers in this repository are organized by vendor. All vendor implementations are located under the /vendor directory. Each vendor has its own subdirectory, which may contain one or more PSA Crypto drivers provided by that vendor.

A typical layout looks like:

vendor/
    vendor_a/
        driver_1/
        driver_2/
    vendor_b/
        driver_1/

Each driver resides in its own directory and includes documentation describing its functionality and usage. The documentation structure within a vendo directory is defined by the vendor.
