 When you specify API hosts in [mTLS authentication](/api-shield/security/mtls/), Cloudflare will block all requests that do not have a [client certificate](/ssl/client-certificates/) for mTLS authentication.

 The second expression uses the `http.request.uri.path` field, combined with the `in` operator, to capture the URI paths your mTLS rule applies to.

+Because the [action](/ruleset-engine/rules-language/actions/) for your rule is _Block_, only requests that present a valid client certificate can access the specified hosts.
+
+For enhanced security, Cloudflare recommends that you validate the SHA-256 certificate hash alongside the verified certificate field. This ensures that only requests presenting a valid client certificate with a specific fingerprint are allowed.
+
+You can implement this by using an expression similar to the following:
+
+```txt
+not (cf.tls_client_auth.cert_verified and cf.tls_client_auth.cert_fingerprint_sha256 eq "253E08C1AB67EB7630C61734D377D75D5DCCDE2F6E69986C221D66E848B64321")
+```
+
+To obtain the SHA-256 fingerprint of a client certificate stored in the `mtls.crt` file, you can run the following OpenSSL command:
+
+```sh
+openssl x509 -noout -fingerprint -sha256 -inform pem -in mtls.crt | cut -d "=" -f 2 | tr -d ':'
