TLSA-Query (_443._tcp.calmpaper.org) sends a valid NSEC3 RR as result with the hashed owner name "er8esourlhkr54lla0gagablte4o837g" (unhashed: calmpaper.org). So that's the Closest Encloser of the query name. TLSA-Query (_443._tcp.calmpaper.org) sends a valid NSEC3 RR as result with the hashed query name "ugi49b6eeg853ci50mlu3325u06ubv3b" between the hashed NSEC3-owner "er8esourlhkr54lla0gagablte4o837g" and the hashed NextOwner "us02hqcfg91akdd5psaamr7s8rtddteh".

So that NSEC3 confirms the not-existence of the Next Closer Name. TLSA-Query sends a valid NSEC3 RR as result and covers the hashed Wildcard expansion of the ClosestEncloser "65l94hvi7de0549b7cous13qc62olhoh" (unhashed: *.calmpaper.org) with the owner "us02hqcfg91akdd5psaamr7s8rtddteh" and the NextOwner "ck4tfdl07d4r6tsk1tr497q6534507cj". So that NSEC3 confirms the not-existence of the Wildcard expansion.

0 DS RR in the parent zone found






DS-Query in the parent zone sends valid NSEC3 RR with the Hash "er8esourlhkr54lla0gagablte4o837g" as Owner. That's the Hash of "calmpaper.org" with the NextHashedOwnerName "us02hqcfg91akdd5psaamr7s8rtddteh". So that domain name is the Closest Encloser of "www.calmpaper.org". Opt-Out: False.
Bitmap: A, NS, SOA, RRSIG, DNSKEY, NSEC3PARAM, CDS Validated: RRSIG-Owner er8esourlhkr54lla0gagablte4o837g.calmpaper.org., Algorithm: 8, 3 Labels, original TTL: 300 sec, Signature-expiration: 17.09.2020, 04:13:24 +, Signature-Inception: 26.08.2020, 04:13:24 +, KeyTag 24478, Signer-Name: calmpaper.org






The ClosestEncloser says, that "*.calmpaper.org" with the Hash "65l94hvi7de0549b7cous13qc62olhoh" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "us02hqcfg91akdd5psaamr7s8rtddteh" and the Next Owner "ck4tfdl07d4r6tsk1tr497q6534507cj", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

7. Comments


1. General Results, most used to calculate the result

Aname "calmpaper.org" is domain, public suffix is ".org", top-level-domain is ".org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)", num .org-domains preloaded: 4686 (complete: 129392)
AGood: All ip addresses are public addresses
Warning: Only one ip address found: calmpaper.org has only one ip address.
Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: calmpaper.org has no ipv6 address.
AGood: No asked Authoritative Name Server had a timeout
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
AGood: every https has a Strict Transport Security Header
AGood: HSTS max-age is long enough, 63072000 seconds = 730 days
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
http://calmpaper.org/ 76.76.21.21

Correct redirect http - https with the same domain name
Mhttps://76.76.21.21/ 76.76.21.21
404

Misconfiguration - main pages should never send http status 400 - 499
Nhttps://76.76.21.21/ 76.76.21.21
404

Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain calmpaper.org, 1 ip addresses.

AGood: All name servers have ipv4- and ipv6-addresses.: 4 different Name Servers found
Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 4 Name Servers, 1 Top Level Domain: com
Warning: All Name Servers have the same domain name. If there is a problem with that domain name (or with the name servers of that domain name), your domain may be affected. Better: Use Name Servers with different domain names / different top level domains.: Only one domain name used: googledomains.com

AGood: All SOA have the same Serial Number
Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.

4. Content- and Performance-critical Checks

AGood: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
AGood: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
https://calmpaper.org/ 76.76.21.21
200

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://calmpaper.org/ 76.76.21.21
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
AGood: Every https connection via port 443 supports the http/2 protocol via ALPN.
https://calmpaper.org/ 76.76.21.21
200

Critical: Some script Elements (type text/javascript) with a src-Attribute don't have a defer / async - Attribute. Loading and executing these JavaScripts blocks parsing and rendering the Html-Output. That's bad if your site is large or the connection is slow / mobile usage. Use "async" if the js file has only functions (so nothing is executed after parsing the file) or is independend. Use "defer" if the order of the scripts is important. All "defer" scripts are executed before the DOMContentLoaded event is fired. Check https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script to see some details.: 3 script elements without defer/async.
AGood: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 5 external CSS / JavaScript files found
Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 3 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 2 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 5 complete.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
AGood: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
