NAME
       gnutls_x509_privkey_export_pkcs8 - API function


SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_privkey_export_pkcs8(gnutls_x509_privkey_t key, gnutls_x509_crt_fmt_t format, const char
       * password, unsigned int flags, 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.

       const char * password
                   the password that will be used to encrypt the key.

       unsigned int flags
                   an ORed sequence of gnutls_pkcs_encrypt_flags_t

       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 PKCS8 structure.  Both RSA and DSA keys can  be  exported.
       For  DSA  keys  we  use  PKCS 11 definitions. If the flags do not specify the encryption cipher, then the
       default 3DES (PBES2) will be used.

       The  password can be either ASCII or UTF-8 in the default PBES2 encryption  schemas,  or  ASCII  for  the
       PKCS12 schemas.

       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 ENCRYPTED PRIVATE KEY" or "BEGIN PRIVATE
       KEY" if encryption is not used.


RETURNS
       In case of failure a negative error code will be returned, and 0 on success.
