Starting October 29, 2025, PrimeSign will implement several changes affecting RKSV signature creation and certificate issuance. These include switching to a new TLS root CA (Sectigo), deactivating TLS 1.0/1.1, requiring SNI support, and expanding the IP range to 149.154.99.176/28. Ensure your systems are updated accordingly, as these changes impact all connection processes with PrimeSign services.

The following changes will take effect on October 29, 2025, when using PrimeSign services for creating RKSV signatures and issuing RKSV certificates:
- Change of the root CA for the TLS connection: The currently used root CA, "Entrust Root Certification Authority - G2," must be replaced with a new CA. Sectigo will be used as the new root CA. Install the following two root certificates: SectigoPublicServerAuthenticationRootE46 and USERTrust ECC Certification Authority (https://www.sectigo.com/knowledge-base/detail/Sectigo-Public-Intermediates-and-Roots/kA0Uj0000003eovKAA ). Primesign recommends keeping trust stores up-to-date regardless of this change. Due to current browser CA developments, it is expected that such long lead times for (root) certificate changes cannot be guaranteed in the future.
- Deactivation of TLS 1.0/1.1: Support for the TLS 1.0/1.1 protocol versions (released in 1999 and 2006, respectively) will be discontinued. Supported protocol versions: TLS 1.2 and TLS 1.3
- SNI mandatory: Ensure that your POS system supports SNI (Server Name Indication). SNI is required for communication with our primesign RKSV Remote Signing Services.
- IP address range extension: The IP addresses of our primesign RKSV Remote Signing Services will be extended to the address range 149.154.99.176/28. If you have currently implemented firewall activations for individual IP addresses, please add the address range 149.154.99.176/28 to these activations.
The changes have been available on the test system since March 26, 2025. Please note that the changes described above when establishing a connection affect both the creation of RKSV signatures and the application for RKSV signature certificates.
