Topic: MakeSelfCert equivalent for ECC

I am looking at the function MakeSelfCert (https://www.wolfssl.com/documentation/m … keselfcert), which appears to only support RSA keys.

So in order to generate a self-signed certificate from ECC key, I will need to perform both steps (MakeCert/SignCert) manually, there is no specific shortcut function that I'm missing, is that correct?

Re: MakeSelfCert equivalent for ECC

Hello Shinzo,

My name is Anthony and I am a member of the wolfSSL team.

Yes, you are correct.  You'll need to use  MakeCert/SignCert in order to use ECC.

Can you please let me know a bit about yourself and your project? What are you trying to achieve? Where are you geographically located? Is this question out of personal, academic or professional interest?  Are there any organizations associated with this work.  Any information is useful in helping us prioritize your request.

Warm regards, Anthony

It appears you're right! RSA keys are supported by MakeSelfCert, therefore you'll need to manually run MakeCert and SignCert to generate an ECC-signed certificate. Current implementation doesn't seem to provide an ECC shortcut. Writing a utility function to automate manual procedures may be efficient!
