NAME

6       gnutls_x509_privkey_get_key_id  - Return unique ID of the key's parame‐
7       ters

SYNOPSIS

10       #include <gnutls/x509.h>
11
12       int gnutls_x509_privkey_get_key_id(gnutls_x509_privkey_t key,  unsigned
13       int flags, unsigned char * output_data, size_t * output_data_size);
14

ARGUMENTS

16       gnutls_x509_privkey_t key
17                   Holds the key
18
19       unsigned int flags
20                   should be 0 for now
21
22       unsigned char * output_data
23                   will contain the key ID
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)

DESCRIPTION

30       This function will return a unique ID the depends  on  the  public  key
31       parameters.  This ID can be used in checking whether a certificate cor‐
32       responds to the given key.
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.  The output will normally be a SHA-1 hash output, which is 20
37       bytes.
38

RETURN VALUE

40       In case of failure a negative value will be returned, and 0 on success.
