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.
