Trình đánh giá Xếp hạng SSL

Cách sử dụng công cụ này

1. 1

   Type a hostname or full URL into the input box (for example example.com or https://example.com) — the tool extracts the hostname and always connects on port 443.

2. 2

   Click 'Grade SSL' to make the server open a TLS connection to that host.

3. 3

   Read the big grade card (A+, A, or F) for the headline result.

4. 4

   Scan the details table for the negotiated protocol, cipher, issuer, and certificate expiry date, plus any warning notes listed below it.

• Confirm a freshly deployed site negotiates TLS 1.3 (A+) rather than silently falling back to TLS 1.2 or older.

• Spot-check an internal or staging host that uses a self-signed certificate, since the tool connects even when the chain does not validate.

• Quickly see a certificate's issuer and expiry date and whether it falls inside the 30-day warning window.

• Catch a server still offering a legacy protocol or an RC4/DES cipher, which immediately scores F.

• Sanity-check a vendor or partner endpoint before integrating, to see what protocol and cipher your client would actually get.

• Demonstrate to a teammate, in seconds, why 'it has HTTPS' is not the same as 'it has a modern TLS configuration'.
