@deftypefun {int} {gnutls_rsa_params_export_pkcs1} (gnutls_rsa_params_t @var{params}, gnutls_x509_crt_fmt_t @var{format}, unsigned char * @var{params_data}, size_t * @var{params_data_size})
@var{params}: Holds the RSA parameters

@var{format}: the format of output params. One of PEM or DER.

@var{params_data}: will contain a PKCS1 RSAPrivateKey structure PEM or DER encoded

@var{params_data_size}: holds the size of params_data (and will be replaced by the actual size of parameters)

This function will export the given RSA parameters to a PKCS1
RSAPrivateKey structure. If the buffer provided is not long enough to
hold the output, then GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.

If the structure is PEM encoded, it will have a header
of "BEGIN RSA PRIVATE KEY".

@strong{Returns:} @code{GNUTLS_E_SUCCESS}  on success, or an negative error code.
