gnutls_x509_privkey_export_pkcs8 − This function will export the private key to PKCS8 format
#include <gnutls/x509.h>
int gnutls_x509_privkey_export_pkcs8(gnutls_x509_privkey_t key, gnutls_x509_crt_fmt_t format, const char * password, unsigned int flags, 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.
const char * password
the password that will be used to encrypt the key.
unsigned int flags
an ORed sequence of gnutls_pkcs_encrypt_flags_t
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 PKCS8 structure. Currently only RSA keys can be exported since there is no documented standard for other keys. If the flags do not specify the encryption cipher, then the default 3DES (PBES2) will be used.
The password can be either ASCII or UTF−8 in the default PBES2 encryption schemas, or ASCII for the PKCS12 schemas.
If the buffer provided is not long enough to hold the output, then *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.
If the structure is PEM encoded, it will have a header of "BEGIN ENCRYPTED PRIVATE KEY" or "BEGIN PRIVATE KEY" if encryption is not used.
In case of failure a negative value will be returned, and 0 on success.
