Schritt 1 – Vorbereitung
Um ein persönliches Zertifikat für Ihren Server oder Ihre Anwendung zu erstellen, müssen Sie zuerst ein CSR (Certificate Signing Request) generieren.

1.) Sie können das CSR File auch über unser Hosting Control Panel erstellen.
2.) Oder über einen CSR Generator wie: https://www.csr-generator.com
3.) Oder direkt auf einem Server mit folgendem Befehl:
openssl req -new -nodes -newkey rsa:4096 -keyout www_telematica_at.key -out www_telematica_at.csr
Bitte ersetzen Sie unseren Domain-Namen mit Ihrer eigenen Domain, für welche Sie ein Zertifikat erstellen möchten.

Verfahren Sie das daraus entstandene CSR File sowie den Private Key sicher auf.

Falls Sie Hilfe benötigen sollten, helfen wir Ihnen natürlich gerne weiter.

Schritt 2 – Bestellung
Sie wählen das gewünschte Zertifikat in unserem Shop aus. Im Bestellvorgang werden Sie aufgefordert, Ihre Daten anzugeben sowie den Inhalt des vorhin erstellten CSR File einzufügen.

Schritt 3 – Validierung
Je nach Validierungsgrad (DV, OV oder EV) durchlaufen Sie ab Bestellung das entsprechende Validierungsverfahren.

Schritt 4 – Zustellung
Nach erfolgreicher Validierung Ihrer Bestellung erhalten Sie das Zertifikat per Mail zugesandt.

1. Authenzifizierungsgrad:

Beim Authenifizierungsgrad  was bei der Ausstellung eines Zertifikats überprüft wird und somit die inwieweit der User dem Zertifikat vertrauen kann.

DV oder “Domain Validation“:
Hierbei wird überprüft, ob der Antragsteller des Zertifikats die beantragte Domain auch tatsächlich kontrolliert, zum Beispiel ein Email empfangen kann oder ein File auf seinen Server hochladen darf.
Ausstellungsdauer: Einige Minuten.

OV oder “Organization Validation“:
Zusätzlich zur Domain Validation wird hier überprüft, ob die beantragende Organisation tatsächlich in dem entsprechenden Land existiert. Hierfür wird ein aktueller Firmenbucheintrag oder Vereinsregistereintrag benötigt. Um die Validierung abzuschließen, wird noch ein Eintrag in das öffentliche Telefonbuch lautend auf den Firmennamen für einen Kontrollanruf der Zertifizierungsstelle verlangt (Hinweis: Ein Eintrag in den gelbe Seiten ist kein Eintrag in einem öffentlichen Telefonbuch).
Ausstellungsdauer: ca. 2-3 Tage

EV oder “Extended Validation“:
Dieses Zertifikat ist die höchste SSL Zertifizierungsform und ist auch als “Green Bar Zertifikat” bekannt. Hier wird neben der “Organization Validation” überprüft, ob es sich beim Antragsteller, um eine kreditwürdige Organisation handelt. Der Antragsteller darf hierfür auf keiner Sperrliste aufscheinen.
Ausstellungsdauer: ca. 1-2 Wochen

2. Schlüssellänge:

Der Private Key des Zertifikates gilt mit 2048-bit als sicher. Der Private Key ist die Grundlage zur Zertifikatsausstellung und bleibt geheim – auch der Zertifikatsstelle kennt diesen Key nicht.

Der Wert der Verschlüsselung gibt an, mit welcher Stärke der Datentransfer zwischen Client und Server verschlüsselt wird. Es gibt folgen Verschlüsselungswerte: 32-, 64-, 96-, 128-, 258-bit. Von einer “strong encryption” spricht man ab 128-bit. Achtung: Sie Schlüssellänge kann vom Zertifikatsantragssteller nicht beeinflusst werden, sondern wird zwischen dem Client und dem Server ausgehandelt.

3. Anzahl Domains im Zertifikat:

Standard-Zertifikate unterstützen pro Zertifikat einen Domain. Comodo bietet als Bonus, dass im Fall von “www.” auch die Domain ohne www vom Zertifikat unterstützt wird. Wenn die Sub-Domain allerdings nicht auf www. lautet, dann fällt dieser Bonus weg.

Wildcard-Zertifikate werden für beliebige Sub-Domains ausgestellt. Das Zertifikat lautet dann beispielsweise auf *.telematica.at. Wenn es sich um unterschiedliche Toplevel-Domain-Namen handelt (zB .at und .de), können Wildcards nicht verwendet werden.

Multi-Domain-Zertifikate fassen mehrere Domains unter einem Zertifikat zusammen. Jede geschützte zusätzliche Domain wird als SAN (Subject Alternate Name) bezeichnet.

Comodo Code Signing Certificates

Code Signing Digital IDs

What is Code Signing?
When customers buy software in a store, the source of that software is obvious.
Customers can tell who published the software, and they can see whether the package has been opened. These factors enable customers to make decisions about what software to purchase and how much to “trust” those products. Customers who download digital ly signed Active X controls, dynamic link libraries, .cab files or HTML content from your site can be confident that code really comes from you and hasn’t been altered or corrupted since it was created and signed. Digital IDs serve as virtual “shrink wrap” for your software: after you sign your code, if it is tampered with in any way, the digital signature will break and alert customers that the code has been altered and is not trustworthy.
