Detailed Description

Primitive operations and data structures for the CRACEN PSA driver.

Note
These primitives are shared between the public driver API and internal implementation.

This module provides primitive data structures and constants, shared between the public driver API and internal implementation.

Warning
The structs in this module contain sensitive data. If used directly, you must make sure that they are correctly wiped after usage to avoid leaking sensitive data.

Unless otherwise specified, all size and length defines are in bytes.
