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
       or RSA-PSS keys, and integer sequence for DSA keys. Other keys types
       will be exported in PKCS8 form.

       If the structure is PEM encoded, it will have a header of "BEGIN RSA
       PRIVATE KEY".

       It is recommended to use gnutls_x509_privkey_export_pkcs8() instead of
       this function, when a consistent output format is required.

RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.
