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.
