gnutls_x509_privkey_export(3)

NAME
gnutls_x509_privkey_export - API function

SYNOPSIS
#include <gnutls/x509.h>

int gnutls_x509_privkey_export(gnutls_x509_privkey_t key, gnutls_x509_crt_fmt_t format, void * output_data, size_t * output_data_size);

ARGUMENTS

gnutls_x509_privkey_t key
    Holds the key

gnutls_x509_crt_fmt_t format
    the format of output params. One of PEM or DER.

void * output_data
    will contain a private key PEM or DER encoded

size_t * output_data_size
    holds the size of output_data (and will be replaced by the actual size of parameters)

DESCRIPTION
This function will export the private key to a PKCS1 structure for RSA keys, or an integer sequence for DSA keys. The DSA keys are in the same format with the parameters used by openssl. If the buffer provided is not long enough to hold the output, then *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned. If the structure is PEM encoded, it will have a header of "BEGIN RSA PRIVATE KEY".

RETURNS
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.
