7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       void  gnutls_srp_set_client_credentials_function(gnutls_srp_client_cre‐
12       dentials_t             cred,     gnutls_srp_client_credentials_function
13       * func);
14

ARGUMENTS

16       gnutls_srp_client_credentials_t         cred
17                   is a gnutls_srp_server_credentials_t type.
18
19       gnutls_srp_client_credentials_function         * func
20                   is the callback function
21

DESCRIPTION

23       This  function  can  be used to set a callback to retrieve the username
24       and password for client SRP authentication.   The  callback's  function
25       form is:
26
27       int (*callback)(gnutls_session_t, char** username, char**password);
28
29       The  username and  password must be allocated using gnutls_malloc().
30
31       The   username  should be an ASCII string or UTF-8 string. In case of a
32       UTF-8 string it is recommended to be following the PRECIS framework for
33       usernames (rfc8265). The password can be in ASCII format, or normalized
34       using gnutls_utf8_password_normalize().
35
36       The callback function will be called once per handshake before the ini‐
37       tial hello message is sent.
38
39       The  callback  should  not return a negative error code the second time
40       called, since the handshake procedure will be aborted.
41
42       The callback function should return 0 on success.  -1 indicates an  er‐
43       ror.
