I'm also seeing: - openssl req -verbose -new -nodes -utf8 -days 10000 -batch -x509 -sm3 -sigopt distid:1234567812345678 -config test-ca.conf -copy_extensions copyall -newkey sm2 -out test-sm2.cer -outform DER -keyout test-sm2.key req: Unrecognized flag copy_extensionsThis command is for openssl 3.0, and '-copy_extensions copyall' is also a parameter supported on 3.0. At present, the mainstream version of openssl 1.1.1 only partially supports SM2 signatures. For example, the USERID in the SM2 specification cannot be used, and the certificate cannot be operated in the command using the SM2/3 algorithm combination, just like the modification of libimaevm.c in this patch, this cannot be done directly through the openssl command, even if the '-copy_extensions copyall' parameter is deleted, this command will be failed on openssl 1.1.1. The final solution may be openssl 3.0. On openssl 1.1.1, there is no problem to operate the signature of the SM2/3 algorithm combination through the API. If it is possible, the sign_verify test of sm2/3 is not required. What is your opinion?
Instead of dropping the test altogether, add an openssl version dependency. thanks, Mimi
