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 keys, or an integer
       sequence for DSA keys.  The DSA keys are in the same format with the  parameters  used  by
       openssl.

       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 RSA PRIVATE KEY".

RETURNS

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