Hi,

If I have an X509 object and is created using PEM_read_bio_X509_AUX(), then
Can I free X509 right after the completion of PEM_read_bio_X509_AUX()?

                               BIO *cert_bio = BIO_new(BIO_s_mem());
                                X509 *cert = X509_new();
                                BIO_puts(cert_bio, cert_str.c_str());
                                cert = PEM_read_bio_X509_AUX(cert_bio,
&cert, NULL, NULL);
                                if ( (cert != NULL) &&
SSL_CTX_use_certificate(ctx, cert) < 1) {
                                        SSL_CTX_free(ctx);
                                        return NULL;
                                }

                                if(cert_bio !=NULL) {
                                        BIO_free(cert_bio);
                                }
                                if(cert != NULL) {
                                        X509_free(cert); //is it needed?
                                }


Thanks
Adi
