+
+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.
+
