You have confidential information for us?
If you would like to send confidential information to us, you have several options to do so. You could, for example, send us an e-mail with a password protected file attached to it. However, that will only be possible if you have agreed on a password for the file with us.
You could also write us a letter, visit us in our office or give us a call.
There’s also the possibility of communicating via encrypted e-mails. The entire message will be protected from access by unauthorized persons, not only the attachment. There will be no need to exchange passwords in this case.
If you would like to send an encrypted e-mail to one of our employees, you will need the public key. You can find this key under “Download of the public keys”.
Imagine this situation:
You know that people want to give you valuable things from time to time, but you don’t know who, when or where. Since you cannot meet up for a personal handover every time, you produce a large amount of padlocks. All these locks have an identical key, with which the locks can be locked securely, but not unlocked: this is the “public key”.
There is only one general key that unlocks all the locks – and it belongs to you. This is what’s called the “private key”.
You hand out the padlocks with the public key to anyone that’s interested. You can also just leave them out for anyone to find, so that any person that wishes to send you a little treasure can simply pick up a lock and the public key along with it.
The sender simply takes a treasure chest in the right size for their gift to you and locks it with the padlock. The chest is then sent to you. Only you can open it with your private key.
Open the software you use for E-mailing and find the contact details for our employee who you would like to contact (or create one if it does not exist).
Now you can import the key into the contact.
This is done differently depending on your mail program, but the principle is always the same:
- For Microsoft Office 2007 Outlook and earlier versions, in the default contact perspective click on the button “Certificate” and then on the option “Import”
- From Microsoft Office 2010 Outlook and onwards, open the contact in its own window. In the menu ribbon “Contact” in the area that says “Display”, click on the [Certificates] button. Then select [Import …].
The dialog “Search certificate…” will open. Find the small file that you downloaded and stored previously. Now you just have to confirm and the key will be stored in the contact.
If you now write an e-mail to one of our e-mail addresses, the mail is protected with the public key. And it can only be opened by the person who has the corresponding private key – namely only the recipient of the e-mail personally.
