MAXIMUM VALIDITY TIME FOR SERVER CERTIFICATES CHANGES ON SEP 1ST
The international certificate community has decided to limit validity for server certificates to 398 days beginning from September 1st, 2020. The selection between one and two-year certificates will be removed from Telia Certificate Service. It will be possible to order only one-year certificates from September 1st.
AN UPDATE TO CLIENT CERTIFICATE CHAIN
Telia has changed certification chain for client certificate on November 14th 2019. A new certification chain will be set to all client certificates from this date on. New chain looks like this:
TeliaSonera Root CA v1 → TeliaSonera Class 1 CA v2 → client certificate
The old chain begins with Sonera Class 2 CA which will now disappear from certification chain. This root certificate will expire on April 5th 2021. After this date certificate with old chain may not appear as trusted.
This change does not require any action by customer. Server software using old versions may cause untrusted certificate errors to appear. If this happens, it is necessary to add TeliaSonera Root CA v1 self-signed root certificate into certificate store of the server. This certificate is available for download at Telia root certificate download service. Assistance is available at firstname.lastname@example.org.
New certification has been used for several years in server certificates so there is no need for changes for server certificate customers.
