gnutls_x509_privkey_export_pkcs8(3) gnutls gnutls_x509_privkey_export_pkcs8(3)

NAME
       gnutls_x509_privkey_export_pkcs8	 -  This function will export the pri‐
       vate key to PKCS8 format

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  defini‐
       tions.  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  encryp‐
       tion 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.

RETURN VALUE
       In case of failure a negative value will be returned, and 0 on success.
