Api function
Usage
#include <gnutls/gnutls.h>
int gnutls_dh_params_export_pkcs3(gnutls_dh_params_t params, gnutls_x509_crt_fmt_t format, unsigned char * params_data, size_t * params_data_size);
Arguments
- gnutls_dh_params_t params
-
Holds the DH parameters
- gnutls_x509_crt_fmt_t format
-
the format of output params. One of PEM or DER.
- unsigned char * params_data
-
will contain a PKCS3 DHParams structure PEM or DER encoded
- size_t * params_data_size
-
holds the size of params_data (and will be replaced by the actual size of parameters)
Overview
This function will export the given dh parameters to a PKCS3 DHParams structure. This is the format generated by "openssl dhparam" tool. 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 DH PARAMETERS".
Returns
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned.
