Post subject:  [QUESTION] Yubico PAM Module

Why is default calling API server over unsecure HTTP? Is it secure? Why there is no HTTPS?

http://api.yubico.com/wsapi/2.0/verify?id=%d&otp=%s

Please read the manual. If you feel the default behavior should be different open a github issue on the relative project and lets discuss about it.

Quote:
"urllist": List of URL templates to be used. This is set by calling
ykclient_set_url_bases. The list should be in the format :

"https://server/wsapi/2.0/verify;https://server/wsapi/2.0/verify"

"url": This option should not be used, please use the urllist
option instead.
Specify the URL template to use, this is set by calling
yubikey_client_set_url_template, which defaults to:

https://api.yubico.com/wsapi/verify?id=%d&otp=%s

or

https://api.yubico.com/wsapi/2.0/verify?id=%d&otp=%s
