5 X509_get0_sm2_id, X509_set0_sm2_id - get or set SM2 ID for certificate operations
9 #include <openssl/x509.h>
11 ASN1_OCTET_STRING *X509_get0_sm2_id(X509 *x);
12 void X509_set0_sm2_id(X509 *x, ASN1_OCTET_STRING *sm2_id);
16 X509_get0_sm2_id() gets the ID value of an SM2 certificate B<x> by returning an
17 B<ASN1_OCTET_STRING> object which should not be freed by the caller.
19 X509_set0_sm2_id() sets the B<sm2_id> value to an SM2 certificate B<x>. Calling
20 this function transfers the memory management of the value to the X509 object,
21 and therefore the value that has been passed in should not be freed by the
22 caller after this function has been called.
26 SM2 signature algorithm requires an ID value when generating and verifying a
27 signature. The functions described in this manual provide the user with the
28 ability to set and retrieve the SM2 ID value.
32 X509_set0_sm2_id() does not return a value.
