EFR HR 2.9.5
What's new?
Croatian fiscalization now signs XML messages and computes the ZKI security code with RSA and SHA256 instead of the outdated SHA1 algorithm. This resolves the FIS_ERR "invalid digital signature" rejections seen against the tax authority's test environment and aligns the middleware with the current signing requirements.
What this means for our users?
If you operate in Croatia, receipts are signed with the algorithm the tax authority expects — no rejected fiscalization messages, no manual intervention, and you stay compliant as the SHA1 phase-out proceeds.
