Free SSL -免費憑證申請流程

Let’s Encrypt 介紹

Let’s Encrypt 是由許多大公司以及各大非營利團體為了推廣 HTTPS 而贊助的一家免費發佈 SSL certificate 的 Certificate Authority。
無論是你的個人網站還是官網,可以透過以下流程申請免費的 SSL 憑證。

Let’s Encrypt 官方限制

Let’s Encrypt 目前已經正式開放,但有發行數量限制,一般人可能會遇到的:

  • Names/Certificate:單一 certificate 限制 100 個 hostname。
  • Certificates/Domain:每個 domain 每個禮拜最多 20 個 certificate,但 renew 不計算在 quota 內 (需要憑證內的 hostname 與之前完全一樣)。
  • Certificates/FQDNset:相同 hostname 的憑證每個禮拜最多發出五個。

最新的資訊以及完整的細節請參考「Rate Limits – Let’s Encrypt – Free SSL/TLS Certificates」這邊的說明。
