gnutls_x509_privkey_export(3)	     gnutls	   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	*   out-
     put_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 ac-
		 tual 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  PRI-
     VATE 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.
