NAME
gnutls_x509_privkey_export_pkcs8 - This function will export the
private key to PKCS8 format
SYNOPSIS
#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);
ARGUMENTS
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)
DESCRIPTION
This function will export the private key to a PKCS8 structure. Both
RSA and DSA keys can be exported. For DSA keys we use PKCS 11
definitions. 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.
RETURN VALUE
In case of failure a negative value will be returned, and 0 on success.
