Hi,
Does the following piece of code have any problem? I got i = 0 when I first
run it yesterday night, but a couple minutes later when I run it again, i =
-1. I passed the same thing to this function. I think it shouldn't gave
different results, am I right?
bool is_user_accessible(unsigned char **cert, unsigned int cert_len, unsigned
char *document_filename, unsigned int filename_len) {
bool return_value = false;
BIO *in = BIO_new(BIO_s_mem());
BUF_MEM *bm = BUF_MEM_new();
X509 *x = NULL;
X509_NAME *name;
ASN1_OBJECT *obj;
int i, last;
X509_NAME_ENTRY *ne;
ASN1_STRING *common_name = NULL, *email = NULL;
BIO_set_mem_buf(in, bm, 0);
BIO_write(in, *cert, cert_len);
if ((x = (X509 *)PEM_read_bio_X509(in, NULL, NULL, NULL)) != NULL) {
name = (X509_NAME *)X509_get_subject_name(x);
/* common name */
obj = OBJ_nid2obj(NID_commonName);
i = X509_NAME_get_index_by_OBJ(name, obj, last);
if (i >= 0) {
ne = X509_NAME_get_entry(name, i);
common_name = X509_NAME_ENTRY_get_data(ne);
}
/* more code follows */
}
