NAME

6       gnutls_srp_set_client_credentials_function - API function
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 * func);
13

ARGUMENTS

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

DESCRIPTION

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