A				Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A				Good: default-src without 'unsafe-inline' or 'unsave-eval'.
E				Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.

A				Good: No object-src found, but the default-src used as fallback is defined and restricted.
F				Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
A				Good: script-src without * and a scheme found.
A				Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.

	3. DNS- and NameServer - Checks
A	Info:: 10 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 3 Name Servers.
A	Info:: 10 Queries complete, 10 with IPv6, 0 with IPv4.
A	Good: All DNS Queries done via IPv6.
	Ok (4 - 8):: An average of 3.3 queries per domain name server required to find all ip addresses of all name servers.
A	Info:: 3 different Name Servers found: ns1.101domain.com, ns2.101domain.com, ns5.101domain.com, 3 Name Servers included in Delegation: ns1.101domain.com, ns2.101domain.com, ns5.101domain.com, 3 Name Servers included in 1 Zone definitions: ns1.101domain.com, ns2.101domain.com, ns5.101domain.com, 1 Name Servers listed in SOA.Primary: ns1.101domain.com.
A	Good: Only one SOA.Primary Name Server found.: ns1.101domain.com.
A	Good: SOA.Primary Name Server included in the delegation set.: ns1.101domain.com.
A	Good: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns1.101domain.com, ns2.101domain.com, ns5.101domain.com
A	Good: All Name Server Domain Names have a Public Suffix.
A	Good: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
A	Good: All Name Server ip addresses are public.
A	Good: Minimal 2 different name servers (public suffix and public ip address) found: 3 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.: 3 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: 101domain.com
A	Good: Name servers with different Country locations found: 3 Name Servers, 2 Countries: CA, US
A	Info: Ipv4-Subnet-list: 4 Name Servers, 1 different subnets (first Byte): 162., 1 different subnets (first two Bytes): 162.159., 2 different subnets (first three Bytes): 162.159.24., 162.159.25.

	Fatal: All Name Server IPv6 addresses from the same subnet.
A	Good: Nameserver supports TCP connections: 8 good Nameserver
A	Good: Nameserver supports Echo Capitalization: 8 good Nameserver
A	Good: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 8 good Nameserver
A	Good: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 8 good Nameserver
A	Good: All SOA have the same Serial Number
A	Good: CAA entries found, creating certificate is limited: amazon.com is allowed to create certificates
A	Good: CAA entries found, creating certificate is limited: digicert.com is allowed to create certificates
	4. Content- and Performance-critical Checks
A	Good: 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.
A	Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).

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.

A	Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 18 external CSS / JavaScript files found
A	Good: All images with internal compression not compressed. Some Images (.png, .jpg, .jpeg, .webp, .gif) are already compressed, so an additional compression isn't helpful. 37 images (type image/png, image/jpg) found without additional GZip. Not required because these images are already compressed
A	Good: All CSS / JavaScript files are sent with a long Cache-Control header (minimum 7 days). So the browser can re-use these files, no download is required. 18 external CSS / JavaScript files with long Cache-Control max-age found
A	Good: All images are sent with a long Cache-Control header (minimum 7 days). So the browser can reuse these files, no download is required. 37 image files with long Cache-Control max-age found
A	Good: All checked attribute values are enclosed in quotation marks (" or ').
A	Good: Some img-elements have a valid alt-attribute.: 37 img-elements found, 36 img-elements with correct alt-attributes (defined, not an empty value).
	Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 1 img-elements without alt-attribute, 0 img-elements with empty alt-attribute found.
A	Good: 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
