On 4th of February 2026, we will restore standard OCSP responder certificate parameters in our service. Your action might be required to maintain uninterrupted signing operations.

Please note that DigiDoc4j versions 5.1.0 through 6.0.1 will no longer function without your intervention, and digital signing using Mobile-ID, Smart-ID, ID cards, and e-Seals will fail.

Upgrading to version 6.1.0, released 15 December 2025, resolves this incompatibility and includes updated cryptographic standards for the coming years.

We urge you to verify which DigiDoc4j version you are using and if needed upgrade to DigiDoc4j library version 6.1.0 or later. This version resolves library compatibility issues that will affect signing operations from 4 February 2026 onwards.

If you cannot upgrade immediately, you can also use a workaround to override the DSS library’s constraint configuration within your environment. Technical instructions are available at the RIA GitHub repository (DigiDoc4j Questions & Answers section here).

Systems not affected

• DigiDoc4j versions 6.1.0 and later
• DigiDoc4j version 5.0.0 and earlier
• RIA’s SiGa signing service
• DigiDoc Client

If you encounter technical obstacles with the library please contact RIA support at klient@ria.ee
