This Website can also been acessed by a secure https-Connection delivered via the "DANE/TLSA Mechanism" to cryptologically assure that a valid PKIX-CA (in this case the "GC Laborchemikalien Root CA" Authority) in the supplied Server Certificate Chain has been issued by a DNSSEC-authorized Domain Holder.
If You still got some trust problems in accessing this site as a SSL/TLS-Secured DANE https-Site, indicating the Server's CA-Certificate not being trustworthy, then simply download the "GC Laborchemikalien Root CA" Certificate and the "GC Laborchemikalien Subordinate CA" and the "GC_SubCA_2048"prior to access the secure version of this Website and install both certificates into Your OS and/or Browser trusted Cert-Store!
To generally benefit from this technique, Your Browser nowadays still reqires a special Plugin to be installed (which can be downloaded "here" ) in Order to successfully validate the Certificates DNSSEC/TLSA-Fingerprints.
