LIBHSE

I am using bsp 40. I am getting the following error when i try to encrypt and decrypt data using libhse. Is it because there is a need to explicitly allocate buffers in HSE reserved memory?

Hello, @ashwini2024

Thanks for the post and sorry for the late reply.

I suggest developing the code based on libpkcs for hash related operation.

And I will update your support case in 1-2 days with examples based on libpkcs. you may check the status there no later than this Thursday.

If it's not too much trouble, could you also kindly share the complete procedure for how the code can be integrated into the system, compiled, and executed?

This would help me better understand the implementation process and ensure I can execute it correctly without missing any steps.

Thank you in advance for your time and support!

Hello, @ashwini2024

Sure, I have basically finished the development of it based on the examples of libpkcs, once finished the test, I will update the procedure of building, integrating, excecuting to the support case you created.

I suggest checking the status of your case late today or tomorrow.

Hello, @ashwini2024

You are very welcome.

I found a bug during the test this afternoon, and plan to fix it soon, I could confirm that your case will be updated by tomorrow.

You may check the sample/procedure in your support portal.

Sorry for your inconvenience.

Hello, @ashwini2024

Thanks for your reply.

Seems you were working based on the libhse, I've finished the example code for you, and updated it in your case, you may reference it directly.
