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Croatian fiscalization now signs XML messages and computes the ZKI security code with RSA and SHA256 instead of the outdated SHA1 algorithm.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.
