Since around the beginning of March 2021, Swisscom AIS customers have been receiving notifications that they should migrate to the new CA4 root certificates.
The changeover must be completed by the end of 2021.

What to do?

To migrate to the new root certificates, simply adapt the ClaimedID in your installation to the value you received in your cover letter and restart the software.

  • In Sign Live! cloud suite gears you will find the associated settings e.g. B. in C: \ ProgramData \ cloudsuite \ config \
  • In Sign Live! CC client you will find the associated settings under the menu option Extras> Settings> Signatures> Signature devices> Mass signature or On Demand


  • for seal: CUSTOMER: static-saphir2-ch -> CUSTOMER: static-saphir4-ch
  • for personal signatures: CUSTOMER: OnDemand-Qualified -> CUSTOMER: OnDemand-Qualified4

What will this change for you?

  • Your signatures are better protected against attacks because of the stronger algorithms now to be used for creating the signature.
  • The eGov validation portal can currently not yet check the signatures created in this way.
  • Further, detailed information can be found in the PDFs that you received in the notification from Swisscom.
