RE: ECDSA certificate question

[Yan, Bob via openssl-users]

Thanks Michael,

I tried to invoke SM3 algorithm in command "openssl req -new -key eckey.pem 
-x509 -sm3 -nodes -days 365 -out cert.csr", unfortunately got the following 
error:

140320586413888:error:100C508A:elliptic curve 
routines:pkey_ec_ctrl:invalid digest type:crypto/ec/ec_pmeth.c:331:

I don't know the detail with the SM3, part, but have you seen:

  https://datatracker.ietf.org/doc/html/draft-moskowitz-ecdsa-pki-09
  https://github.com/rgmhtt/draft-moskowitz-ecdsa-pki

but, 1.1.1 release notes say it supports SM3. I expect you need to tweak 
something when "openssl req" is run.

ECDSA certificate question

[Yan, Bob via openssl-users]

Hello everybody,

Is there a way to generate a ECDSA certificate with SM2 typed public key and 
ecdsa-with-SM3 as the signature algorithm in openssl 1.1.1x version?

Thank you very much!
Bob
