"使用有 SHA-256 或更高哈希運算法則的 TLS 憑證。現代的瀏覽器不信任使用 SHA-1 的憑證。"
持續使用 SHA-1 憑證會使您用戶端的敏感資料面臨風險，而且將導致瀏覽器顯示警告。連線到網站時，警告創造了不信任，而且可能導致用戶端避開您的網站。
哈希運算法則用於產生 SSL 憑證。「探索」會檢查您的 SSL/TLS 憑證，以及其發行的中介憑證。
根據目前的研究和 DigiCert 的建議，系統管理員應該用 SHA-2 憑證取代他們的 SHA-1 憑證，因為與 SHA-1 哈希運算法則關聯的風險比之前預期的大。發佈的發現似乎沒有立即的危險，因為我們強烈建議系統管理員盡快規劃可行的方式移轉為使用 SHA-2 憑證。

重新發行、續訂或以 SHA-2 憑證取代您的所有 SHA-1 憑證。如需詳細指示，請參閱切換到 SHA-2。
