gnutls_x509_privkey_export - API function

#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);*

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)

This function will export the private key to a PKCS*1* structure for RSA or RSA-PSS keys, and integer sequence for DSA keys. Other keys types will be exported in PKCS*8* form.

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

It is recommended to use gnutls_x509_privkey_export_pkcs8() instead of this function, when a consistent output format is required.

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