Why not to use and accept such a certificate?


If you use such a certificate the visitors of your website will receive an error message every time they wish to use the site. The expired certificates lead to mistrust among customers and visitors and considerably reduce the quality of the site.


Due to the above reasons we propose to give confidential information exclusively on sites protected by SSL certificates from reliable Certification Authority as well as protect also your own website with such a certificate.
