The price of two years EV certificate is more cheaper than other competitors's in Taiwan. StartSSL EV quotes USD$199( closing to TWD 6,000 ), and the same level competitors in Taiwan quote TWD 55,000 ~ 90,000. Yes, you did not lost, the ten times expensiveness.
But it costs something else, because the www.startssl.com is a Israel company, we must verify the personal and company authorization with law notarization first. This law jobs spend our half month. Anyway, we done, and obtain a real green bar certificate now.
After i install and configure certificate in Nginx Server, Chrome and IE can pop up rightly, but Firefox alerts a "sec_error_unknown_issuer" message to me.
The solution is catching "sub.class4.server.ca.pem"( Exclusive only for Extended Validation Cert ) and "ca.pem" into your_example_domain.crt file, and the order must be "your_domain_crt", "sub.class4.server.ca.pem" and "ca.pem". You can find the two files in the www.startssl.com/certs/.
Below is my Nginx conf:
Finally, i got a green internet address bar. So happy~
