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 PKCS1 structure for RSA or RSA−PSS keys, and integer sequence for DSA keys. Other keys types will be exported in PKCS8 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.
