You can do something like this: (assuming the cert is a variable -- if the
cert is a file in the filesystem, some modificatins is needed)
#include ...
int main(int argc, char **argv)
{
X509* pCert;
char* str;
int ret;
char clientCertificate[] = "-----BEGIN CERTIFICATE-----\r\n\
// the PEM certificate data
-----END CERTIFICATE-----";
BIO* mem = BIO_new_mem_buf(clientCertificate,
strlen(clientCertificate));
pCert = PEM_read_bio_X509(mem,NULL,NULL,NULL);
str =X509_NAME_oneline (X509_get_issuer_name(pCert),NULL,0);
printf ("\t Issuer: [%s]\n", str);
BIO_set_close(mem,BIO_NOCLOSE);
BIO_free(mem);
return 0;
}
