14
16 gnutls_srp_client_credentials_t cred
17 is a gnutls_srp_server_credentials_t type.

19 gnutls_srp_client_credentials_function * func
20 is the callback function
21
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
43 error.
