New EU-CH timestamp unit

We issue a new timestamp on June 14th 2am-6am, which is considered "qualified" in both the EU and Switzerland. It replaces the up-to-date Swiss qualified timestamp. This timestamp has the following root/intermediate CAs:

  • Root: Swisscom Root CA4
  • Intermediate: Swisscom TSS CA 4.1
  • Swisscom TSU 4.1

There are very slight changes in the signature size - here we ask you to pay attention to whether there are problems with the signature application. With regard to the change to CA4 in the autumn, the signature size has to be adjusted accordingly anyway. More detailed calculations can be found here: Customers are asked to contact their partner managers if they see problems beforehand.
