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);
Using of X509_NAME_oneline() is discouraged(See the man page). Instead use X509_NAME_print_ex(out, X509_get_issuer_name(pCert), 0,0); as in my previous reply. Cheers, Kau
