       gnutls_srp_set_client_credentials_function - API function

SYNOPSIS         top

ARGUMENTS         top

       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         top

       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,

       The  username and  password must be allocated using

       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.
