=head1 NAME

X509_get0_sm2_id, X509_set_sm2_id - get or set SM2 ID for certificate operations

=head1 SYNOPSIS

 #include <openssl/x509.h>

 ASN1_OCTET_STRING *X509_get0_sm2_id(X509 *x);
 void X509_set_sm2_id(X509 *x, ASN1_OCTET_STRING *sm2_id);

=head1 DESCRIPTION

X509_get0_sm2_id() gets the ID value of an SM2 certificate B<x> by returning an
B<ASN1_OCTET_STRING> object which should not be freed by the caller.
X509_set_sm2_id() sets the B<sm2_id> value to an SM2 certificate B<x>.

=head1 NOTES

SM2 signature algorithm requires an ID value when generating and verifying a
signature. The functions described in this manual provide the user with the
ability to set and retrieve the SM2 ID value.

=head1 RETURN VALUES

X509_set_sm2_id() does not return a value.
