Platform Security Architecture (PSA) API structures for nRF Security.

The nRF Security subsystem provides integration between Mbed TLS and hardware-accelerated cryptographic libraries through PSA drivers. These structures define the implementation-specific context types used in the PSA Crypto API.

The crypto_driver_contexts_* files are Nordic-specific implementations for the corresponding crypto_driver_contexts_* files in the Oberon API. This API is defined in sdk-nrf at https://github.com/nrfconnect/sdk-nrf/tree/main/subsys/nrf_security/include/psa and should be consulted together with the three Nordic-specific files.

Nordic-specific implementations are designed to extend available cryptographic features with hardware acceleration or alternative implementations. The supported drivers include:

Arm CryptoCell cc3xx (hardware acceleration for nRF52840, nRF91 Series, and nRF5340)
nrf_oberon (optimized cryptographic algorithms)
CRACEN (hardware acceleration for nRF54L and nRF71 Series)

For detailed documentation on these drivers, see the nRF Connect SDK documentation: https://nrfconnectdocs.nordicsemi.com/ncs/latest/nrf/libraries/security/nrf_security.html

The Nordic-specific implementation also uses files located at:
