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 (0) is returned, otherwise a negative error value.
