how can I set a cloudflare ssl setting?

what is cloudflare's ssl setting?

select your tls/ssl encryption

off:no ssl

flexible:encrypt cloudflare-user not server-cloudflare

full:end to end encryption (you can use non-CA certification)

full(strict):you must use trusted CA certificate or cloudflare's certification

the recommendation about setting is full (strict)

after setting is done, press the save button
