gnutls_dh_params_export_pkcs3 - API function

SYNOPSIS¶

#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)

DESCRIPTION¶

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".
