How to generate EC Key pair in se050x based on user input

krsuresh — Tue, 20 Feb 2024 07:55:06 GMT

Hi Team,

In the nano-package code, we can see that an EC key pair is generated or a key is written to SE050 for the sign-in process. But for us the EC key pair must be generated inside SE050 based on user input, because the same key pair need be regenerated in case the device is lost.

Please assist us in generating EC key pairs based on user input in SE050 and sign-in process.

Thanks,

Hi @krsuresh ,

Such kind of tool is already there but not within the nano package, please download the full version of MW with the following link https://www.nxp.com/webapp/Download?colCode=SE05x-PLUG-TRUST-MW&appType=license , and refer to the doc of simw-top/doc/cli-tool.html for details.

This tool can work standalone as below or be used within some python script (Please refer to "simw-top\sss\plugin\openssl_provider\scripts\openssl_provisionEC.py" for details, alternatively please refer to simw-top/doc/pycli/Provisioning/readme.html for more details.).

Hope that helps,

Have a great day,
Kan
