When I looked up the source code of seTool, I found that the source code only implemented the function of NIST-P256, but did not support NIST-P384 or NIST-P521. Do you have a reference demo

Thanks

Hi @haichao

We don't support this product, sorry.

Best regards

Hi,@Harvey021

I found that using seTool and using ssscli to obtain the same keyid (NIST_P256) differ in the obtained ref.pem. Why is this

Why does seTool only implement acquisition (NIST_256), not implementation (NIST_P384, etc.), and cannot find relevant examples in the demo, making it difficult for users to implement them themselves

Thanks
