Hi @Chenxu1

HSE-B supports ED448. From HSE Service API reference manual:

Hi @lukaszadrapa

Thank you for your response.

You mentioned that ED448 is supported on HSE-B, but based on the HSE Service API Reference Manual and the release notes, it appears that ED448 is not supported. Could you please double-check this for us?

Hi @KaiKim

It seems I was wrong. I went through a couple of API manuals and some contains this information, some not. I was probably looking at one which didn't show this information. But when looking at hse_b_config.h in interface files in different versions, all of them contain:

So, it's really not supported.
Thanks for pointing this out.
