I have an application where I have to create a partial x509 certificate.  It

I was calling

     X509_new
     X509_set_version
     X509_set_issuer_name
     X509_get_notBefore
     X509_get_notAfter
     X509_set_subject_name
     X509_EXTENSION_create_by_OBJ

and then
     i2d_x509
to send the serialized partial certificate to the HSM.

This worked in 1.0.1, 1.0.2, 1.1.1, but fails in 3.0.0.

In debugging, even this fails.

     X509_new
     i2d_x509

Suggestions?

Following up, I found that just omitting the signature from the
X509 structure causes i2d_x509 to fail.

I tried i2d_re_X509_tbs(), but it also failed.
