Hello, does NXP provide a Cryptographic Service Engine (CSE) Quality Package? If so, where can it be obtained? Thank you!

Hi @CZJ-UPDATE2025

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.

BR, VaneB

Hi, VaneB. I only found the relevant test documents about RTD_CSEc from the link you provided. However, for the csec module (such as csec_driver.c) in the SDK I am using, I couldn't find any relevant information. I hope to get your help and support.

Hi @CZJ-UPDATE2025

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.
