If you are using Real-Time Drivers (RTD) for S32K1 or S32M24X devices, the same page where the software can be downloaded also provides QualityPackage.zip and SafetyPackage.zip (Real-Time Drivers for S32K1 → Automotive SW - S32K1_S32M24x - Real-Time Drivers for Cortex-M). These packages include documentation related to the Crypto driver, such as test reports, the RTD Safety Manual, and other relevant materials.

As you mentioned, the previously referenced package only provides support for Real-Time Drivers (RTD). The Quality Package for the S32 Software Development Kit (SDK) for S32K1 is available under a Non-Disclosure Agreement (NDA). Therefore, we recommend creating a support ticket or contacting your NXP representative for further support regarding this matter.
