NAME

6       gnutls_x509_privkey_export - API function
7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int        gnutls_x509_privkey_export(gnutls_x509_privkey_t        key,
12       gnutls_x509_crt_fmt_t  format,  void  *  output_data,  size_t  *   out‐
13       put_data_size);
14

ARGUMENTS

16       gnutls_x509_privkey_t key
17                   Holds the key
18
19       gnutls_x509_crt_fmt_t format
20                   the format of output params. One of PEM or DER.
21
22       void * output_data
23                   will contain a private key PEM or DER encoded
24
25       size_t * output_data_size
26                   holds  the size of output_data (and will be replaced by the
27                   actual size of parameters)
28

DESCRIPTION

30       This function will export the private key to a PKCS1 structure for  RSA
31       keys,  or  an  integer  sequence for DSA keys.  The DSA keys are in the
32       same format with the parameters used by openssl.
33
34       If the buffer provided is not long enough  to  hold  the  output,  then
35       *output_data_size  is  updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be
36       returned.
37
38       If the structure is PEM encoded, it will have a header  of  "BEGIN  RSA
39       PRIVATE KEY".
40

RETURNS

42       On  success,  GNUTLS_E_SUCCESS  is returned, otherwise a negative error
43       value.
