API function

Synopsis

#include <gnutls/gnutls.h>

void gnutls_srp_set_client_credentials_function(gnutls_srp_client_credentials_t         cred, gnutls_srp_client_credentials_function         * func);

Arguments

gnutls_srp_client_credentials_t         cred

is a gnutls_srp_server_credentials_t type.

gnutls_srp_client_credentials_function         * func

is the callback function

Description

This function can be used to set a callback to retrieve the username and password for client SRP authentication.  The callback's function form is:

int (*callback)(gnutls_session_t, char** username, char**password);

The  username and  password must be allocated using gnutls_malloc().

The  username should be an ASCII string or UTF-8 string. In case of a UTF-8 string it is recommended to be following the PRECIS framework for usernames (rfc8265). The password can be in ASCII format, or normalized using gnutls_utf8_password_normalize().

The callback function will be called once per handshake before the initial hello message is sent.

The callback should not return a negative error code the second time called, since the handshake procedure will be aborted.

The callback function should return 0 on success. -1 indicates an error.
