Private homepage of Sietze Roorda
Welcome to my homepage. Please have a look!
If you're coming from Kurt Reinhardt's pages at the FH Mannheim: No, I am not a famous cryptographer. However, I used to work for a company specialized in all matters relating to PKI called SECUDE IT Security GmbH. Most of the company's assets have been sold to SAP and I have moved on as well.
Although not a big plane spotter, when I have the possibility, I do try to photograph planes. Some pictures I got are published on Planepictures.net.
