gnutls_rsa_params_export_pkcs1 — API function


#include <gnutls/compat.h>
int gnutls_rsa_params_export_pkcs1( gnutls_rsa_params_t params,
  gnutls_x509_crt_fmt_t format,
  unsigned char * params_data,
  size_t * params_data_size);


gnutls_rsa_params_t params

Holds the RSA parameters

gnutls_x509_crt_fmt_t format

the format of output params. One of PEM or DER.

unsigned char * params_data

will contain a PKCS1 RSAPrivateKey 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)


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".


GNUTLS_E_SUCCESS on success, or an negative error code.
