Hi,<br>
<br>
I'm trying to get OpenSSL 1.0.2u with the FIPS Object Module
2.0.16 in Windows 10 to prompt the user for a smart card's PIN
number every time the application is launched. However, I cannot
seem to get it to work. My UI_METHOD callback functions are not
being invoked.<br>
<br>
I'm using the following code as a reference:<br>
<a class="moz-txt-link-freetext" href="https://github.com/jjkeijser/ppp/blob/eap-tls/pppd/eap-tls.c">https://github.com/jjkeijser/ppp/blob/eap-tls/pppd/eap-tls.c</a><br>
<br>
I tried the following:<br>
<br>
<blockquote><font face="monospace">UI_METHOD* transfer_pin =
UI_create_method("transfer_pin");<br>
<br>
int writer (UI *ui, UI_STRING *uis)<br>
{<br>
PW_CB_DATA* cb_data = (PW_CB_DATA*)UI_get0_user_data(ui);<br>
UI_set_result(ui, uis, cb_data->password);<br>
return 1;<br>
};<br>
int stub (UI* ui) {return 1;};<br>
int stub_reader (UI *ui, UI_STRING *uis) {return 1;};<br>
<br>
UI_method_set_writer(transfer_pin, writer);<br>
UI_method_set_opener(transfer_pin, stub);<br>
UI_method_set_closer(transfer_pin, stub);<br>
UI_method_set_flusher(transfer_pin, stub);<br>
UI_method_set_reader(transfer_pin, stub_reader);<br>
<br>
pkey = ENGINE_load_private_key(pkey_engine, pkey_identifier,
transfer_pin, &cb_data);<br>
</font></blockquote>
<br>
<br>
However, none of the callback functions "writer", "stub", or
"stub_reader" actually get called. Do I need to do anything else to
enable this functionality? I would like to force the user to enter
PIN number every time.<br>
<br>
<br>
<br>
Thanks,<br>
George<br>
